Product details
Overview
HS5MH from Taiwan Semiconductor is a 1000V, 5A surface-mount high-efficiency fast recovery rectifier in DO-214AB (SMC) package, featuring 1.70V max forward voltage at 5A/25°C, 75ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-voltage DC-DC converters.
For engineers reviewing the HS5MH datasheet, HS5MH pinout, HS5MH application, or HS5MH equivalent, key selection factors include peak reverse voltage rating (1000V), thermal resistance (60°C/W), junction capacitance (50pF), and compliance with JESD201 Class 2 whisker testing and RoHS/halogen-free standards.
Technical Context
The HS5MH uses a single-die, glass-passivated silicon junction optimized for high-voltage switching applications. Its 1000V VRRM and 150A IFSM support robust surge handling in automotive power supplies and industrial snubbers.
With a 75ns reverse recovery time and 50pF junction capacitance at 1MHz/4V, the HS5MH balances speed and low capacitive loading-critical for minimizing switching losses in 100–500kHz DC-DC topologies where voltage stress exceeds 600V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports primary-side rectification in offline SMPS and high-bus automotive systems |
| IF | 5 A continuous - rated for sustained conduction in 12–48V output DC-DC stages with thermal derating above 75°C |
| VF @ 5A, 25°C | 1.70 V max - limits conduction loss to ≤8.5W at full load, enabling compact heatsinking |
| trr | 75 ns - reduces turn-off switching loss and EMI in hard-switched flyback and forward converters |
| RθJA | 60 °C/W - requires ≥25 mm² copper pour for safe operation at 5A in ambient ≤70°C |
| Junction Capacitance | 50 pF @ 1MHz, 4V - minimizes capacitive coupling noise in high-dv/dt gate-drive snubbers |
| AEC-Q101 | Qualified - validated for automotive underhood temperature cycling (-55°C to +150°C) and mechanical shock |

| Cathode | Current exit terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive); carries full load current |
Key Features
| Feature | Design Value |
|---|---|

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-5EWH10 | Same 1000V VRRM, 5A IF, but 1.85V VF @ 5A and 100ns trr; TO-277 package (smaller footprint, no leads) | Higher forward loss and slower recovery limit efficiency in high-frequency (>300kHz) designs | Select if board space is constrained and thermal management prioritizes package size over conduction loss |
| ON Semiconductor MUR5100CT | 1000V, dual common-cathode configuration; 1.75V VF @ 5A; 100ns trr; TO-220AC package | Dual-diode layout suits bridge configurations; through-hole mounting requires manual assembly or wave soldering | Select only when dual-diode functionality or through-hole assembly is required; not drop-in compatible |
Compared with VS-5EWH10 and MUR5100CT, the HS5MH delivers lower conduction loss (1.70V vs. ≥1.75V) and faster recovery (75ns vs. ≥100ns) in a leaded SMC package that supports automated reflow and meets AEC-Q101-making it optimal for automotive and high-reliability industrial DC-DC outputs.

FAQ
What is the maximum junction temperature rating for HS5MH?
The HS5MH has a maximum junction temperature (TJ) of +150°C, verified per AEC-Q101 stress testing. This rating allows continuous operation in underhood automotive environments when mounted on ≥25 mm² copper area and derated per the forward current derating curve. The HS5MH maintains specified electrical parameters up to this limit, with IR rising to 250 µA at 125°C.
Is HS5MH suitable for use in automotive lighting applications?
Yes, HS5MH is qualified to AEC-Q101 and used in automotive LED headlamp drivers as a freewheeling diode. Its 1000V VRRM, 150A IFSM, and operation up to +150°C junction temperature meet OEM requirements for adaptive front-lighting systems. The HS5MH's low profile and SMC package support automated assembly in space-constrained ECU layouts.
What is the reverse recovery time (trr) specification for HS5MH?
The HS5MH has a reverse recovery time (trr) of 75 ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the official Taiwan Semiconductor datasheet Version A2102 and enables efficient operation in 200–500kHz DC-DC converters where fast switching transitions minimize energy loss during diode turn-off.
Does HS5MH have halogen-free and RoHS-compliant construction?
Yes, HS5MH is halogen-free per IEC 61249-2-21 and RoHS compliant, with matte tin-plated leads and UL 94V-0 molding compound. These material attributes are documented in the Taiwan Semiconductor HS5AH–HS5MH datasheet Version A2102 and support compliance with automotive OEM environmental directives and EU WEEE recycling requirements.
What packaging and reel quantity is available for HS5MH?
HS5MH is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, per the ordering code HS5MH and standard packing specification in the Taiwan Semiconductor datasheet. This configuration supports high-speed pick-and-place assembly and is compatible with industry-standard SMT feeders used in automotive electronics manufacturing.
