HER151-TP

Single Diodes Overview

The HER151-TP is a single-phase, high-efficiency silicon rectifier manufactured by Micro Commercial Components (MCC). It features a DO-15 through-hole package and supports an average forward current of 1.5 A at 55°C ambient temperature. The device has a maximum recurrent peak reverse voltage of 50 V and a maximum RMS voltage of 35 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.0 V at 1.5 A, a maximum reverse recovery time of 50 ns, and a typical junction capacitance of 50 pF measured at 1.0 MHz. It withstands a peak forward surge current of 50 A for an 8.3 ms half-sine wave.

Single Diodes Feature Summary

• High surge current capability designed to handle transient electrical loads
• Low forward voltage drop to minimize energy losses during conduction
• High reliability with epoxy meeting UL 94 V-0 flammability rating
• Wide operating temperature range from -55°C to +125°C

Single Diodes Applications

• Single-phase half-wave rectification in resistive or inductive circuits
• Power supply input stages operating at 60 Hz
• General-purpose rectification for low-voltage DC conversion

Single Diodes Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format. The -TP suffix indicates tape and reel packaging containing 4,000 pieces per reel. Ensure compliance with moisture sensitivity level 1 requirements during storage and handling. Confirm that the application does not involve life support systems without explicit manufacturer approval.

Single Diodes Selection Notes

Select this component for applications requiring a 50 V reverse voltage rating and 1.5 A continuous current capacity. Consider the 50 ns reverse recovery time for standard frequency rectification tasks. Evaluate thermal derating requirements if the ambient temperature exceeds 55°C. Verify lead length dimensions fit the target PCB layout constraints.

Single Diodes Part Context

This part belongs to the HER151 through HER158 series of 1.5 Amp High Efficient Rectifiers. The series covers peak reverse voltages ranging from 50 V to 1000 V within the same DO-15 package family. All variants share identical physical dimensions and thermal characteristics while differing in voltage ratings and specific electrical parameters like reverse recovery time.

Single Diodes Replacement Considerations

Direct substitutes within the same series include HER152-TP through HER158-TP, provided the circuit voltage rating allows for higher breakdown voltages. Cross-manufacturer replacements must match the 1.5 A current, 50 V reverse voltage, and DO-15 package footprint.
