1N5342BRL

Single Zener Diodes Overview

The onsemi 1N5342BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, featuring a nominal reverse Zener voltage of 6.8 V with a ±5% tolerance. It operates in an axial lead DO-15 (Surmetic 40) plastic package and supports through-hole mounting. The device handles a maximum steady-state power dissipation of 5 W at a lead temperature of 75°C, with a junction-to-lead thermal resistance of 25 °C/W. Electrical characteristics include a test current of 175 mA, a maximum dynamic impedance of 1 Ω, and a maximum reverse leakage current of 10 μA. It withstands a non-repetitive surge current up to 5.2 A for an 8.3 ms pulse width.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and shipping configuration. The 'R' suffix indicates tape and reel packaging containing 4000 units, while the 'G' suffix denotes a lead-free compliant package. Confirming these details ensures compatibility with automated assembly processes and regulatory requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference is required within a 5 W power dissipation envelope. Ensure the application circuit can accommodate the specified 175 mA test current and manage heat sinking effectively to maintain junction temperatures below the 200°C absolute maximum limit during operation.

Single Zener Diodes Part Context

This part belongs to the 1N53xxB series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a broad voltage range from 3.3 V to 200 V, utilizing a standardized axial lead plastic package designed for robust performance in common industrial environments.

Single Zener Diodes Replacement Considerations
