Taiwan Semiconductor Corporation HER3002PTH

Overview

HER3002PTH from Taiwan Semiconductor is a 30A, 100V AEC-Q101-qualified high-efficiency rectifier in TO-247AD package, featuring dual-die construction, 1.0V forward voltage at 15A/25°C, 50ns reverse recovery time, and 1.4°C/W junction-to-case thermal resistance for automotive and industrial switching power supplies.

For engineers reviewing the HER3002PTH datasheet, HER3002PTH pinout, HER3002PTH application, or HER3002PTH equivalent, key selection criteria include peak repetitive reverse voltage (100V), surge current capability (300A), thermal performance under high-current DC-DC operation, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This device integrates two independent high-efficiency rectifier dies in a single TO-247AD package, enabling dual-channel or parallel-configured freewheeling paths. Its low V_F (1.0V typ. @ 15A) and fast trr (50ns max) reduce conduction and switching losses in high-frequency SMPS topologies.

The 1.4°C/W R_θJC, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound support reliable thermal management and solder joint integrity in thermally demanding environments up to 150°C junction temperature.

FAQ

What is the peak repetitive reverse voltage rating for HER3002PTH?

The HER3002PTH has a peak repetitive reverse voltage (V_RRM) rating of 100 V, as specified in the absolute maximum ratings table. This value is fixed for the HER3002PTH variant and distinguishes it from other members of the HER300xPT family, such as HER3001PTH (50 V) and HER3003PTH (200 V). The 100 V rating makes HER3002PTH suitable for 12 V and 24 V automotive and industrial bus applications where moderate reverse blocking is required without over-specifying voltage margin.

Is HER3002PTH qualified to AEC-Q101 standards?

Yes, HER3002PTH is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and stated in the FEATURES section. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-ensuring suitability for automotive under-hood applications. The AEC-Q101 status applies specifically to HER3002PTH and other "H"-suffixed variants in the HER300xPT family, not to standard "PT" versions.

What is the forward voltage drop of HER3002PTH under typical operating conditions?

The typical forward voltage (V_F) of HER3002PTH is 1.0 V at 15 A and 25°C junction temperature, per the Electrical Specifications table. At elevated temperatures (e.g., 125°C), V_F decreases slightly due to semiconductor physics, but remains within 1.05 V. This low V_F directly reduces conduction losses-critical for maintaining >95% efficiency in high-current DC-DC converters using HER3002PTH as the output rectifier.

Does HER3002PTH have a dual-die configuration, and how is it implemented?

Yes, HER3002PTH uses a dual-die configuration housed in a single TO-247AD package, with two anodes and one common cathode. This structure is verified in the MECHANICAL DATA and KEY PARAMETERS sections. It allows independent routing of two AC inputs to a shared DC output, supporting applications like dual-output flyback converters or phase-interleaved rectification-without requiring external paralleling components or additional packaging area.

What is the maximum junction temperature and thermal resistance of HER3002PTH?

HER3002PTH has a maximum junction temperature (T_JMAX) of +150°C and a junction-to-case thermal resistance (R_θJC) of 1.4°C/W, as published in the THERMAL PERFORMANCE section. These values are measured under standard mounting conditions with proper heatsink interface. The 1.4°C/W R_θJC enables effective thermal transfer when mounted to aluminum heatsinks, allowing HER3002PTH to sustain 30 A continuous current at ambient temperatures up to 85°C with appropriate thermal design.
