Product details
Overview
HERAF1606GH from Taiwan Semiconductor is a single-die, AEC-Q101-qualified high-efficiency rectifier in ITO-220AC package, rated for 16 A average forward current, 600 V repetitive peak reverse voltage, and 250 A surge capability. It delivers 1.7 V forward voltage at 16 A and 25°C, with 80 ns reverse recovery time and 110 pF junction capacitance - optimized for automotive-grade DC/DC converters and freewheeling paths.
For engineers reviewing the HERAF1606GH datasheet, HERAF1606GH pinout, HERAF1606GH application, or HERAF1606GH equivalent, key selection factors include its 600 V VRRM rating, AEC-Q101 qualification, thermal resistance of 2°C/W, low trr for high-frequency switching, and UL recognition (E-326243) for safety-critical power stages.
Technical Context
This device is a glass-passivated, single-junction silicon rectifier diode designed for high-reliability power conversion. Its 600 V VRRM and 250 A IFSM support robust operation under transient overloads in automotive and industrial inverters.
The 80 ns reverse recovery time and 110 pF junction capacitance reflect optimization for switching-mode topologies operating up to several hundred kHz. Thermal performance is anchored by a 2°C/W junction-to-case resistance, enabling direct heatsink mounting without thermal interface material in many applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16EWH06-M3 | Same ITO-220AC package, 16 A/600 V, but VF = 1.85 V (max), trr = 75 ns, no AEC-Q101 claim | Targeted at industrial/commercial SMPS; lacks automotive qualification documentation | Select when AEC-Q101 is not required and slightly higher VF is acceptable |
| ON Semiconductor MUR1660CTG | TO-220AB dual common-cathode configuration, 16 A/600 V per diode, VF = 1.75 V (max), trr = 60 ns, AEC-Q101 not claimed | Requires dual-diode layout; intended for general-purpose rectification, not automotive | Choose only if dual-diode topology is needed and automotive compliance is unnecessary |
Compared with VS-16EWH06-M3 and MUR1660CTG, HERAF1606GH uniquely combines AEC-Q101 qualification, 600 V rating, and 1.7 V VF in a single-diode ITO-220AC package - making it the only option qualified for automotive power conversion where single-diode simplicity and reliability are mandatory.

FAQ
What is the maximum junction temperature rating for HERAF1606GH?
The HERAF1606GH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating applies under continuous operation with proper heatsinking and accounts for thermal derating above 25°C ambient. The device's 2°C/W junction-to-case resistance enables reliable operation at full 16 A load within this limit when mounted to an adequately sized heatsink. HERAF1606GH must not be operated beyond this temperature to ensure long-term reliability and AEC-Q101 compliance.
Is HERAF1606GH pin-compatible with other devices in the HERAF16xxG family?
Yes, all HERAF16xxG variants-including HERAF1606GH-share identical ITO-220AC packaging, pinout (anode, cathode, isolated tab), and mechanical dimensions. Voltage ratings differ (50 V to 600 V), but electrical connections and mounting are fully interchangeable. HERAF1606GH retains the same anode/cathode lead assignment and tab polarity as HERAF1601G through HERAF1605G, enabling drop-in replacement in layouts designed for the family-provided voltage and VF requirements are met.
Does HERAF1606GH require a thermal pad or insulator when mounted to a heatsink?
HERAF1606GH uses an ITO-220AC package with electrically isolated tab, meaning the metal case is not internally connected to either anode or cathode. While isolation eliminates mandatory insulation, a thermally conductive but electrically isolating pad (e.g., silicone-based) is recommended to maximize heat transfer while preserving system-level galvanic isolation. Mounting torque must not exceed 0.56 N·m to avoid package damage. HERAF1606GH's design supports direct heatsink attachment only if cathode-referenced grounding is acceptable.
What does the "H" suffix in HERAF1606GH signify?
The "H" suffix in HERAF1606GH explicitly denotes AEC-Q101 qualification, as confirmed in the ordering information section of the Taiwan Semiconductor datasheet (Version K2105). This means HERAF1606GH has undergone stress testing-including temperature cycling, humidity bias HAST, and mechanical shock-to meet automotive-grade reliability standards. Non-H variants (e.g., HERAF1606G) lack this qualification and are intended for commercial/industrial use only. HERAF1606GH is certified for use in automotive power electronics where functional safety and long-term stability are critical.
How does the 80 ns reverse recovery time of HERAF1606GH impact switching efficiency?
The 80 ns reverse recovery time (trr) of HERAF1606GH directly affects switching losses in high-frequency converters: shorter trr reduces the duration of reverse conduction and associated power dissipation during turn-off transitions. At 200 kHz operation, this value keeps recovery-related losses below 5% of total diode losses, supporting >95% efficiency in well-designed LLC or phase-shifted full-bridge topologies. HERAF1606GH's trr is measured under standardized conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), ensuring consistent benchmarking against competing rectifiers.
