Product details
Overview
HER1606G from Taiwan Semiconductor is a 16A, 600V high-efficiency ultrafast recovery rectifier diode in TO-220AB package, featuring 1.7V max forward voltage at 8A/25°C, 80ns reverse recovery time, and dual-die construction for enhanced thermal performance in high-frequency switching power supplies.
For engineers reviewing the HER1606G datasheet, HER1606G pinout, HER1606G application, or HER1606G equivalent, key selection criteria include its 600V repetitive peak reverse voltage, 125A surge rating, 1.5°C/W junction-to-case thermal resistance, AEC-Q101 qualification option (HER1606GH), and suitability for freewheeling and DC-DC converter designs requiring low conduction loss and fast recovery.
Technical Context
This device is a single-phase, dual-die ultrafast recovery rectifier optimized for high-frequency switching topologies. Its 80ns trr and low 1.7V VF at 8A enable reduced switching losses and improved efficiency in SMPS operating above 50kHz.
The TO-220AB package provides direct heatsink mounting with 0.56 N·m max torque, while the 1.5°C/W RθJC supports sustained 16A conduction at ≤150°C junction temperature under proper thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16EWH06FN-M3 | Same 600V VRRM, 16A IF, but TO-247AC package; 1.65V VF @ 8A; 75ns trr | Higher thermal mass and larger footprint; better suited for forced-air-cooled systems | Choose when board space permits larger TO-247 and superior surge robustness is required |
| ON Semiconductor MUR1660CT | 600V VRRM, 16A IF, TO-220AB; 1.85V VF @ 8A; 60ns trr; single-die construction | Lower trr but higher VF; less thermal margin at full load due to single-die layout | Prefer where faster recovery dominates over conduction loss, e.g., resonant LLC primaries |
Compared with VS-16EWH06FN-M3 and MUR1660CT, HER1606G delivers optimal balance of low VF, adequate trr, and proven dual-die thermal reliability in TO-220AB-making it ideal for cost-sensitive, thermally constrained 16A SMPS designs where 1.7V VF directly translates to measurable efficiency gain.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HER1606G?
The HER1606G has a specified VRRM of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version J2104). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is strictly assigned to the HER1606G variant-not extrapolated from adjacent part numbers like HER1605G (400 V) or HER1607G (800 V).
Does HER1606G have AEC-Q101 qualification?
The base HER1606G is not AEC-Q101 qualified; however, the HER1606GH variant-identical in all electrical and thermal specifications-is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening, and both parts share the same TO-220AB package, 600 V VRRM, and 1.7 V VF rating.
What is the forward voltage (VF) of HER1606G at 16A?
The datasheet specifies VF only at 8A (≤1.7 V, TJ = 25°C); no VF value is published at 16A. At full-rated current, VF will increase due to resistive heating and should be estimated using the typical forward characteristic curve (Fig.4), where HER1606G-1608G shows ~2.1 V at 16A and 25°C ambient-subject to derating at elevated junction temperatures.
Is HER1606G a single-diode or dual-diode device?
HER1606G is a dual-die rectifier housed in a single TO-220AB package. As stated in the KEY PARAMETERS section, "Configuration: Dual dies." This architecture splits the 16A current across two paralleled silicon dies, improving thermal distribution and reliability compared to single-die equivalents of similar rating.
What is the junction-to-case thermal resistance (RθJC) of HER1606G?
The HER1606G has a typical RθJC of 1.5°C/W, as published in the THERMAL PERFORMANCE table of the official datasheet. This value applies to the TO-220AB package with proper mounting torque (≤0.56 N·m) and thermal interface material, enabling accurate heatsink sizing for continuous 16A operation at ≤150°C junction temperature.
