Product details
Overview
HER1603GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified dual-die ultrafast rectifier in TO-220AB package, rated for 200 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF), and 125 A non-repetitive surge current (IFSM); used in automotive-grade DC/DC converters and switching inverters.
For engineers reviewing the HER1603GH datasheet, HER1603GH pinout, HER1603GH application, or HER1603GH equivalent, key selection criteria include its 200 V VRRM rating, 1.0 V typical forward voltage at 8 A/25°C, 50 ns reverse recovery time, dual-die configuration, and AEC-Q101 qualification for under-hood power conversion.
Technical Context
This device integrates two independent high-efficiency rectifying dies in a single TO-220AB thermally optimized package, enabling shared thermal path and compact layout in bidirectional or dual-output topologies. Its ultrafast trr ≤ 50 ns and low VF support high-frequency switching up to 100 kHz in synchronous rectification and freewheeling roles.
The HER1603GH operates across –55°C to +150°C junction temperature range with 1.5°C/W junction-to-case thermal resistance, supporting conduction loss reduction in space-constrained automotive power modules where thermal management and reliability are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-HER1603H | Identical VRRM (200 V), IF (16 A), and TO-220AB package; trr = 50 ns (same), VF = 1.05 V (slightly higher) | No AEC-Q101 qualification; rated for industrial, not automotive temperature cycling | Select for cost-sensitive industrial SMPS where automotive qualification is unnecessary |
| ON Semiconductor MUR1620CT | 200 V VRRM, 16 A IF, TO-220AB, but single-die dual-common-cathode; trr = 60 ns, VF = 1.15 V | Higher VF and slower trr increase conduction/switching loss; no AEC-Q101 certification | Acceptable for non-automotive 12 V/24 V converters where thermal margin exceeds 10°C |
Compared with VS-HER1603H and MUR1620CT, the HER1603GH uniquely combines AEC-Q101 qualification, dual-die architecture, and 1.0 V VF - making it the only option qualified for under-hood automotive DC/DC where reliability, thermal symmetry, and efficiency are jointly constrained.

FAQ
What is the maximum junction temperature rating for HER1603GH?
The HER1603GH has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from –55°C to +150°C. This rating supports continuous operation in under-hood automotive environments when mounted on an appropriate heatsink with ≤1.5°C/W thermal resistance. The HER1603GH's thermal performance is specified per JEDEC standards and confirmed in TSC's AEC-Q101 qualification report.
Is HER1603GH pin-compatible with standard TO-220AB rectifiers like MUR1620CT?
The HER1603GH uses a standard TO-220AB outline with 3 terminals (Anode 1, Cathode, Anode 2), matching mechanical footprint and mounting hole positions of MUR1620CT. However, internal pin function differs: MUR1620CT is dual-common-cathode, while HER1603GH is dual-anode/common-cathode. PCB redesign is required to maintain correct polarity and circuit topology when substituting HER1603GH.
Does HER1603GH support bidirectional current flow?
No - the HER1603GH is a unidirectional rectifier. Each die conducts only from anode to cathode; the dual-anode configuration enables two independent forward paths sharing one cathode node, but reverse blocking remains active per diode. It does not function as a bidirectional switch or ideal diode controller. For true bidirectional conduction, external MOSFET-based solutions are required.
What is the marking code for HER1603GH on the device body?
The HER1603GH is laser-marked with "HER1603GH" followed by date code (YWW format) and factory identifier (e.g., "F"). The "H" suffix explicitly denotes AEC-Q101 qualification, distinguishing it from non-qualified HER1603G variants. Marking conforms to JEDEC standards and appears on the top surface of the TO-220AB package near the tab edge.
How does the dual-die structure of HER1603GH affect thermal performance compared to single-die alternatives?
The dual-die structure in HER1603GH shares a common thermal path through the TO-220AB copper tab, resulting in identical RθJC (1.5°C/W) per die. Unlike two discrete devices, this configuration avoids thermal coupling penalties and ensures balanced junction temperatures under asymmetric loading - critical for reliability in automotive applications where localized hot spots must be avoided.
