Product details
Overview
HS1MH from Taiwan Semiconductor is a 1A, 1000V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AC (SMA) package, featuring 1.7V forward voltage at 1A and 75ns reverse recovery time, used in snubber circuits and high-voltage DC-DC converters.
For engineers reviewing the HS1MH datasheet, HS1MH pinout, HS1MH application, or HS1MH equivalent, key selection criteria include its 1000V VRRM, AEC-Q101 qualification, glass-passivated junction, moisture sensitivity level 1 rating, and suitability for automotive-grade switching-mode power supplies.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-efficiency switching applications. Its fast recovery (75ns) and low junction capacitance (15pF at 1MHz, 4V) support high-frequency operation in SMPS and inverters.
The HS1MH operates across -55°C to +150°C junction temperature range with 30A non-repetitive surge capability and thermal resistance of 15°C/W (junction-to-lead), enabling reliable performance under transient load conditions on standard PCB copper pads.

| IFSM | 30 A - handles short-duration surges without failure in motor drive freewheeling |
| VF | 1.7 V @ 1A, 25°C - contributes to <1.7W conduction loss per device at full load |

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-1EWH10 | Same DO-214AC package, 1000V VRRM, but 1.3V VF and 50ns trr; not AEC-Q101 qualified | Better efficiency in high-frequency SMPS; unsuitable for automotive qualification-critical designs | Select when lowest conduction/switching loss is prioritized over automotive compliance |
| ON Semiconductor MUR110 | DO-41 through-hole, 1000V VRRM, 1.7V VF, 75ns trr, but no AEC-Q101 or moisture level 1 rating | Requires manual or wave soldering; incompatible with automated SMT lines | Select only for legacy through-hole designs where rework flexibility outweighs production scalability |
Compared with VS-1EWH10 and MUR110, the HS1MH uniquely combines AEC-Q101 qualification, moisture level 1, and DO-214AC SMT compatibility-making it the only drop-in solution for automotive-grade, high-volume surface-mount rectification at 1000V.

FAQ
What is the maximum junction temperature rating for HS1MH?
The HS1MH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official datasheet. This allows operation in under-hood automotive environments and enclosed industrial power supplies. Derating curves confirm 1A continuous current is maintainable up to 125°C ambient when mounted on a 5mm × 5mm Cu pad. The HS1MH must not exceed +150°C at the die junction under any operating condition.
Is HS1MH compatible with lead-free reflow soldering processes?
Yes, HS1MH is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level 1 classification eliminates pre-bake requirements. The device is rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020, making it suitable for standard Pb-free SAC305 profiles. The HS1MH's UL 94V-0 molding compound also ensures flame resistance during thermal cycling.
Does HS1MH have AEC-Q101 qualification documentation available?
Yes, HS1MH is explicitly listed as AEC-Q101 qualified in the official Taiwan Semiconductor datasheet (Version B2401). Qualification covers temperature cycling, high-temperature operating life, unbiased highly accelerated stress test, and mechanical shock per AEC-Q101-001 Rev D. Test reports are available upon request from TSC's quality department. The HS1MH's qualification status applies directly to the DO-214AC packaged device, not just the die.
What is the reverse recovery time (trr) of HS1MH and how is it measured?
The HS1MH has a typical reverse recovery time (trr) of 75ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the electrical specifications table. This value is confirmed across the HS1JH–HS1MH subgroup and reflects performance at 25°C ambient. The HS1MH's trr remains stable up to 125°C junction temperature, supporting consistent switching behavior in thermally stressed power stages.
Can HS1MH replace HS1JH or HS1KH in an existing design?
Yes, HS1MH can directly replace HS1JH (600V) and HS1KH (800V) in most designs due to identical DO-214AC package, pinout, thermal characteristics, and forward voltage (1.7V). Its higher 1000V VRRM adds margin against voltage transients, though layout and thermal validation are recommended. The HS1MH maintains the same marking code format (HS1M), cathode band polarity, and solder profile as HS1JH and HS1KH.
