Product details
Overview
HS5DH from Taiwan Semiconductor is a 5A, 500V AEC-Q101-qualified surface-mount high-efficiency rectifier in DO-214AB (SMC) package, featuring 1.00V max forward voltage at 5A/25°C, 50ns reverse recovery time, and 80pF junction capacitance - deployed in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the HS5DH datasheet, HS5DH pinout, HS5DH application, or HS5DH equivalent, key selection criteria include repetitive peak reverse voltage (500V), thermal resistance (60°C/W), junction temperature range (–55°C to +150°C), and compliance with JESD201 Class 2 whisker testing and RoHS/halogen-free standards.
Technical Context
The HS5DH is a single-die, glass-passivated silicon rectifier optimized for high-reliability automotive and industrial power conversion. Its 50ns trr and low VF support efficient high-frequency switching in snubber and freewheeling topologies.
Rated for 5A average forward current and 150A non-repetitive surge (8.3ms), it operates across –55°C to +150°C junction temperature with 60°C/W junction-to-ambient thermal resistance - enabling compact thermal design in space-constrained SMC-mounted layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC-DC flyback or boost stages |
| IF | 5 A - continuous average forward current; supports mid-power automotive subsystems without forced cooling |
| VF @ 5A/25°C | ≤1.00 V - low conduction loss reduces heat generation and improves system efficiency at rated load |
| trr | ≤50 ns - fast recovery minimizes switching losses and EMI in high-frequency (>100 kHz) converters |
| CJ @ 1MHz/4V | 80 pF - low junction capacitance limits displacement current and aids noise control in snubber networks |
| RθJA | 60 °C/W - enables thermal management on standard FR-4 PCBs with minimal copper area |
| TJ Range | –55°C to +150°C - meets under-hood automotive ambient requirements per AEC-Q101 stress test profile |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, low-profile, matte tin-plated leads, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); polarity must align with PCB silkscreen |
| Cathode | Forward current exit / reverse-blocking terminal | Connected to higher-potential rail; cathode band marks this terminal for automated placement verification |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-5EWH05FN-M3/45 | Same DO-214AB package, 5A/500V, but VF = 1.15V @ 5A; trr = 35ns; not AEC-Q101 qualified | Preferred for cost-sensitive industrial supplies where automotive qualification is unnecessary | Select when faster trr is prioritized over AEC-Q101 compliance and lower VF |
| ON Semiconductor MUR550EG | DO-214AC (SMA) package, 5A/500V, VF = 1.25V @ 5A, trr = 35ns, AEC-Q101 qualified | Smaller footprint but lower thermal mass; limited to ≤3.5A continuous in same layout due to higher RθJA | Select when board space is constrained and derated current is acceptable |
Compared with VS-5EWH05FN-M3/45 and MUR550EG, the HS5DH offers the lowest VF (≤1.00V) among AEC-Q101-qualified 5A/500V rectifiers in DO-214AB, delivering superior thermal performance and automotive compliance without sacrificing speed.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated Taiwanese manufacturer specializing in discrete power semiconductors, including rectifiers, TVS, MOSFETs, and IGBTs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS5DH?
The HS5DH has a VRRM of 500 V, meaning it can reliably block reverse voltages up to this level in continuous operation. This rating is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2102). The HS5DH is designed for use in circuits where transient spikes remain within this margin, such as automotive 12V systems with load dump protection. Exceeding 500 V may cause irreversible breakdown.
Is the HS5DH AEC-Q101 qualified, and what does that cover?
Yes, the HS5DH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification includes stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), ensuring suitability for automotive under-hood applications. The HS5DH's qualification applies directly to the HS5DH variant - not inferred from other members of the HS5xH series - and is verified in TSC's certification records.
What is the forward voltage drop (VF) of the HS5DH at rated current?
The HS5DH exhibits a maximum forward voltage drop of 1.00 V at 5 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects conduction loss under typical DC-DC converter operating conditions. At elevated temperatures or higher currents, VF increases predictably per the device's forward characteristic curve.
Does the HS5DH have a defined reverse recovery time (trr), and how is it measured?
Yes, the HS5DH has a maximum reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency converters. The test circuit and waveform definitions are documented in Figure 6 of the TSC HS5xH datasheet (Version A2102), confirming the value applies specifically to the HS5DH variant.
What package type and marking code does the HS5DH use?
The HS5DH uses the DO-214AB (SMC) surface-mount package with matte tin-plated leads and a cathode band for polarity identification. Its marking code is "HS5D", printed on the device body per the Marking Diagram in the TSC datasheet. This matches the ordering code HS5DH and distinguishes it from other variants like HS5AH (50V) or HS5MH (1000V) in the same family.
