Overview
The onsemi 1N5356BRL is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead Surmetic 40 (DO-15) plastic package. It features a nominal reverse Zener voltage of 19 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for environmental protection.
Feature Summary
- Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection
- Provides tight electrical limits guaranteed across multiple parameters including impedance and leakage current
- Features high surge capability rated up to 180 W for non-repetitive pulses
Applications
- Voltage regulation in general-purpose electronic circuits
- Protection against transient overvoltage events
- Reference voltage sources in power supply designs
Procurement Notes
Verify that the ordering suffix 'RL' corresponds to the tape and reel packaging configuration specified in the datasheet. Confirm RoHS compliance status by checking for the 'G' suffix or relevant documentation. Ensure the application environment remains within the specified thermal and voltage limits to maintain reliability.
Selection Notes
Select this component when a 19 V reference with 5 W power handling is required. Consider the axial lead format for through-hole mounting. Evaluate the specific test currents and impedance values against circuit requirements to ensure accurate voltage regulation under expected load conditions.
Part Context
This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators. The series covers a wide voltage range from 3.3 V to 200 V. All devices share common mechanical characteristics, including void-free transfer-molded plastic cases and corrosion-resistant finishes suitable for various mounting positions.
Replacement Considerations
Other parts within the 1N53 Series may serve as substitutes if voltage ratings differ. Verify that any replacement maintains the same power dissipation capabilities and package dimensions for physical compatibility.
