Overview
The onsemi 1N5354BRL is a single-channel Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (Surmetic 40) package. It features a nominal Zener voltage of 17 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a junction 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 limits on electrical parameters including Zener voltage and impedance
- Features a void-free, transfer-molded thermosetting plastic package with corrosion-resistant external surfaces
Applications
- Voltage regulation circuits requiring 5W power handling
- Protection against transient overvoltages and surge events
- General-purpose electronic equipment utilizing axial lead mounting
Procurement Notes
Verify that the ordering suffix 'BRL' corresponds to the tape and reel packaging configuration specified in the official datasheet. Confirm the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure the specific part number matches the manufacturer's current production listing to avoid discrepancies in mechanical or electrical specifications.
Selection Notes
Select this component when a 17V reference with high power capability is required. The 1N5354B variant offers a standard ±5% tolerance suitable for general applications. Consider the thermal resistance characteristics and derating curves above 25°C to ensure reliable operation under continuous load conditions.
Part Context
This device belongs to the 1N5333B through 1N5388B series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3V to 200V, providing options for various regulation needs within the same robust Surmetic 40 package family.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5354B equivalents meeting the 17V/5W specification. Verify that any replacement maintains the same DO-15 axial lead form factor and electrical tolerances.
