Product details
Overview
HT16GH from Taiwan Semiconductor is a 600 V, 1 A glass-passivated high-efficiency rectifier diode in TS-1 package, featuring 1.7 V forward voltage at 1 A and 75 ns reverse recovery time, used in freewheeling paths of automotive DC-DC converters.
For engineers reviewing the HT16GH datasheet, HT16GH pinout, HT16GH application, or HT16GH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), surge current capability (30 A), junction temperature range (–55°C to +150°C), AEC-Q101 qualification, and TS-1 mechanical compatibility with automated SMT assembly.
Technical Context
This device is a single-die, silicon planar epitaxial PN junction rectifier optimized for high-frequency switching applications. Its glass passivation ensures stable junction protection under thermal cycling and humidity stress, while low trr (75 ns) and moderate CJ (10 pF) support efficient operation in 50–500 kHz SMPS topologies.
The TS-1 package provides 95°C/W junction-to-ambient thermal resistance and pure tin-plated leads compliant with J-STD-002 solderability. Polarity is marked by cathode band; device weight is 0.200 g.

| VF @ 1 A, 25°C | 1.7 V - contributes ~1.7 W conduction loss at full load, requiring thermal derating above 75°C ambient |
| trr | 75 ns - enables use in hard-switched converters operating ≤500 kHz with minimal switching loss penalty |
| TJ max | +150°C - allows operation in engine-bay-adjacent locations with validated thermal design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | 600 V, 1 A, TO-277A package, VF = 1.7 V, trr = 60 ns, no AEC-Q101 | Non-automotive industrial use only; lacks automotive qualification and TS-1 footprint | Preferred where faster trr is critical and automotive qualification is not required |
| ON Semi MUR160 | 600 V, 1 A, DO-41 package, VF = 1.7 V, trr = 75 ns, no AEC-Q101 | Through-hole assembly only; higher RθJA (~120°C/W); not qualified for automotive | Used in legacy or cost-sensitive non-automotive designs with manual or wave soldering |
Compared with STTH1R06S and MUR160, HT16GH uniquely combines AEC-Q101 qualification, TS-1 SMT compatibility, and 75 ns trr-making it the only drop-in option for new automotive SMT designs requiring 600 V rectification with production-grade reliability.

FAQ
What is the maximum junction temperature rating for HT16GH?
The HT16GH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 thermal stress testing. This rating enables reliable operation in under-hood automotive environments when mounted on PCBs with adequate copper pour and airflow. Derating curves in the HT16GH datasheet specify usable current versus ambient temperature, with full 1 A rating maintained up to 75°C ambient.
Is HT16GH pin-compatible with other devices in the HT1xG family?
Yes, all HT1xG devices-including HT16GH-share identical TS-1 package dimensions, pinout, and thermal characteristics. Only VRRM (600 V), VF (1.7 V), and trr (75 ns) differ across the family. Engineers may substitute HT11GH through HT18GH without layout changes, provided voltage and timing requirements align with the selected variant's specifications.
Does HT16GH require a heatsink in typical 1 A applications?
HT16GH typically does not require an external heatsink at 1 A continuous current in still air, given its 95°C/W RθJA and 1.7 V VF resulting in ~1.7 W dissipation. However, thermal simulation or board-level testing is recommended when ambient exceeds 75°C or when PCB copper area is limited. The TS-1 package relies on PCB copper for heat spreading, not dedicated heatsink mounting.
What does the 'H' suffix in HT16GH signify?
The 'H' suffix in HT16GH indicates full AEC-Q101 qualification per Rev D, covering stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TC), and unbiased highly accelerated stress test (uHAST). This distinguishes HT16GH from standard HT16G, which shares electrical specs but lacks automotive qualification documentation and screening.
How does HT16GH compare to standard FR107 diodes in switching performance?
HT16GH offers significantly faster reverse recovery (75 ns vs. ≥500 ns for FR107) and lower forward voltage (1.7 V vs. ~1.85 V at 1 A), reducing both switching and conduction losses in 100–300 kHz converters. Unlike FR107's DO-41 package, HT16GH's TS-1 enables automated SMT assembly and better thermal coupling to PCB copper, improving power density and reliability in modern designs.
