Product details
Overview
HER207GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified ultrafast recovery rectifier diode in DO-204AC (DO-15) package, rated for 800 V repetitive peak reverse voltage (VRRM), 2 A average forward current (IF), and 75 ns reverse recovery time (trr). It delivers low forward voltage drop (1.7 V at 2 A, 25°C) and high surge capability (60 A IFSM), targeting automotive-grade DC/DC converters and switching inverters.
For engineers reviewing the HER207GH datasheet, HER207GH pinout, HER207GH application, or HER207GH equivalent, key selection criteria include its AEC-Q101 qualification, 800 V VRRM, 75 ns trr, 1.7 V VF at 2 A, and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This ultrafast rectifier uses a glass-passivated single-die silicon junction optimized for high-frequency switching applications. Its 75 ns reverse recovery time and 20 pF junction capacitance at 1 MHz / 4 V enable efficient operation in 50–500 kHz SMPS topologies without excessive switching loss or EMI generation.
The device operates across –55°C to +150°C junction temperature range and features pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The cathode band clearly indicates polarity on the DO-15 body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports input stages up to 565 V DC bus in industrial AC/DC front-ends |
| IF | 2 A continuous - suitable for medium-power output rectification in 25–60 W converters |
| trr | 75 ns - enables stable operation in hard-switched flyback and forward converters up to 300 kHz |
| VF | 1.7 V @ 2 A, 25°C - reduces conduction loss by ~15% vs. standard FR107 in same layout |
| IFSM | 60 A (8.3 ms half-sine) - withstands inrush and transient overloads in automotive cold-crank scenarios |
| Junction temp | –55°C to +150°C - certified for under-hood automotive environments per AEC-Q101 |
| CJ | 20 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-dv/dt gate-drive snubber paths |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS- and halogen-free molded case with cathode band marking. Weight ≈ 0.400 g.

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-HER208GHE3/45-E3 | Same DO-15 package, 1000 V VRRM, 75 ns trr, but 1.85 V VF @ 2 A - higher conduction loss | Preferred where higher reverse margin is critical (e.g., 600 V AC input), not for 800 V–optimized designs | Select when system requires >800 V blocking with minimal layout change |
| ON Semiconductor MUR280E | DO-201AD package (larger), 800 V VRRM, 75 ns trr, 1.75 V VF; not AEC-Q101 qualified | Suitable for industrial/non-automotive use only; requires footprint revision due to different lead spacing | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with VS-HER208GHE3/45-E3 and MUR280E, HER207GH uniquely balances 800 V rating, AEC-Q101 compliance, and DO-15 compatibility-making it optimal for space-constrained automotive auxiliary supplies where qualification and thermal performance are jointly critical.

FAQ
What does the 'H' suffix in HER207GH signify?
The 'H' suffix in HER207GH indicates full AEC-Q101 qualification per Rev D requirements, including stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress test. HER207GH is not just a screened version-it is a fully qualified automotive-grade part with documented failure analysis and lot traceability, unlike standard HER207G.
Is HER207GH pin-compatible with HER207G?
Yes, HER207GH is mechanically and electrically identical to HER207G in DO-204AC (DO-15) package, sharing identical pinout, dimensions, thermal resistance (60°C/W), and electrical specifications-including 800 V VRRM, 2 A IF, and 75 ns trr. The sole difference is AEC-Q101 qualification and associated process controls.
What is the maximum allowable junction temperature for HER207GH during continuous operation?
The maximum continuous junction temperature for HER207GH is +150°C, validated across its full operating range (–55°C to +150°C). Derating begins at +75°C ambient per the forward current derating curve; at 100°C ambient, maximum IF drops to 1.3 A to maintain TJ ≤ 150°C with RθJA = 60°C/W.
Can HER207GH replace a standard 1N4007 in a 24 V DC power supply?
HER207GH can replace 1N4007 only if the circuit operates below 800 V reverse voltage and benefits from faster recovery. While HER207GH offers lower VF (1.7 V vs. ~1.1 V at low current) and vastly superior trr (75 ns vs. >2 µs), its higher VF at light loads may reduce efficiency in linear supplies. It is best suited for switching topologies-not linear regulators.
Does HER207GH require a heatsink in a 2 A, 25°C ambient application?
No, HER207GH does not require an external heatsink at 2 A and 25°C ambient, provided PCB copper area meets minimum thermal pad guidelines (≥ 1 cm² per lead). With RθJA = 60°C/W, power dissipation of 3.4 W (1.7 V × 2 A) raises junction temperature by 204°C-so adequate copper pour or airflow is essential. At 2 A continuous, ≥ 2 cm² double-sided copper is recommended to hold TJ < 125°C.
