1N5338BRL

Single Zener Diodes Overview

The onsemi 1N5338BRL is a single-channel Zener voltage regulator diode from the 1N53 Series, featuring a nominal breakdown voltage of 200 V with a ±5% tolerance. It operates within an axial lead DO-41 (Surmetic 40) package and supports through-hole mounting. The device handles a maximum steady-state power dissipation of 5 W at 25°C, with a junction-to-lead thermal resistance of 25 °C/W. Electrical characteristics include a reverse leakage current of 500 nA at 200 V, a maximum dynamic impedance of 480 Ω at a test current of 5 mA, and a forward voltage drop of 1.2 V max at 1 A. It withstands non-repetitive surge currents up to 23.6 A for 8.3 ms pulses and functions across a temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junction technology to ensure tight electrical limits and superior operating stability under varying conditions.
• Features void-free, transfer-molded thermosetting plastic encapsulation that provides corrosion resistance and protection against common environmental stressors.
• Offers high surge capability rated up to 180 W for short-duration pulses, supporting robust transient voltage suppression applications.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits requiring stable reference levels
• Transient voltage suppression for circuit protection against surges
• Overvoltage protection stages in industrial control systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'RL' confirms tape-and-reel packaging containing 4000 units per reel, distinct from bulk box configurations. Confirm RoHS compliance status by checking for the 'G' suffix or manufacturer declaration, as standard packages may vary. Ensure the procurement documentation matches the exact JEDEC type number 1N5338B to guarantee the specified 200V nominal rating and ±5% tolerance are met.

Single Zener Diodes Selection Notes

Select this component when a precise 200 V regulation point is required with a ±5% tolerance band. The 5 W power rating necessitates adequate heat sinking or PCB copper area to maintain junction temperatures below 150°C during continuous DC operation. Verify that the system's peak transient voltages do not exceed the 180 W surge rating to prevent device failure.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, utilizing standardized axial lead packages. The 1N5338B variant specifically targets high-voltage regulation needs within this lineup, offering consistent performance characteristics aligned with industry-standard JEDEC specifications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5338B equivalents such as those from Microsemi or STMicroelectronics. Ensure substitute parts match the 200 V nominal voltage, 5 W power dissipation, and DO-41 axial lead package dimensions for direct mechanical compatibility.
