PR1502S-B

Single Diodes Overview

The PR1502S-B is a 1.5A fast recovery rectifier from Diodes Incorporated, housed in a DO-41 plastic package. It features a diffused junction with a peak repetitive reverse voltage of 100V and an average rectified output current of 1.5A at 50°C ambient temperature. The device exhibits a maximum forward voltage of 1.2V at 1.5A and supports a non-repetitive peak forward surge current of 50A. Reverse recovery time ranges from 150 to 250ns, with typical junction capacitance between 10 and 20pF. Operating and storage temperatures span from -65°C to +150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix B corresponds to the DO-41 package configuration as documented in the manufacturer's ordering information table. Confirm that the component meets RoHS compliance standards per revision 13.2.2003, noting applicable exemptions for glass and high-temperature solder. Ensure compatibility with MIL-STD-202 Method 208 for terminal solderability requirements during assembly processes.

Single Diodes Selection Notes

Select this component for circuits requiring a 100V reverse voltage rating and 1.5A continuous current handling. Consider the thermal resistance of 35 K/W when designing heat dissipation strategies. Derate current by 20% if used with capacitive loads. Verify lead maintenance at ambient temperature within 9.5mm of the case to ensure rated performance specifications are met under operating conditions.

Single Diodes Part Context

This part belongs to the PR1501/S through PR1505/S series of 1.5A fast recovery rectifiers. The 'S' suffix specifically denotes the DO-41 package variant, distinguishing it from the DO-15 package options available in the same electrical family. All variants share identical electrical characteristics including current ratings and reverse recovery times, differing only in their peak repetitive reverse voltage capabilities ranging from 50V to 600V across the series.

Single Diodes Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. The datasheet explicitly states this series is not recommended for new design. Engineers should consult current manufacturer catalogs for updated alternatives or verify cross-reference data through official distributor channels before implementation.

Single Diodes FAQ

What is the difference between the PR1502S-B and PR1502-B?

The 'S' suffix indicates the DO-41 package, while the absence of the suffix denotes the DO-15 package. Both parts share the same 100V reverse voltage and 1.5A current ratings.

How does the load type affect current rating?

For capacitive loads, the average rectified output current must be derated by 20% compared to resistive or inductive loads.
