Product details
Overview
HS3FH from Taiwan Semiconductor is a 3A, 300V repetitive peak reverse voltage (VRRM) surface-mount high-efficiency rectifier in DO-214AB (SMC) package, featuring 1.0 V max forward voltage at 3 A and 50 ns max reverse recovery time. It serves as a freewheeling or snubber diode in automotive DC-DC converters and car lighting systems.
For engineers reviewing the HS3FH datasheet, HS3FH pinout, HS3FH application, or HS3FH equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, moisture sensitivity level 1 rating, low-profile SMC package, and verified 150 A IFSM surge capability under 8.3 ms half-sine conditions.
Technical Context
The HS3FH operates as a single-die standard recovery rectifier with unidirectional conduction and cathode-band polarity indication. Its thermal resistance RθJA is 60 °C/W, enabling reliable operation up to 150 °C junction temperature in constrained PCB layouts.
Electrical behavior is defined by a 300 V VRRM, 35 V RMS reverse voltage rating, and 10 µA max reverse leakage at 25 °C - optimized for mid-voltage switching power supplies where fast recovery and low VF trade-offs are balanced for efficiency and EMI control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - supports DC-DC stages with 24–48 V input rails and transient clamping up to 300 V |
| IF | 3 A continuous - delivers rated current without derating at ≤75 °C ambient with standard copper pour |
| IFSM | 150 A (8.3 ms) - withstands inrush and fault currents in automotive load-dump scenarios |
| VF @ 3 A | ≤1.0 V - reduces conduction loss to ≤3.0 W per device at full load, easing thermal design |
| trr | ≤50 ns - limits switching losses and voltage overshoot in 100–500 kHz SMPS topologies |
| TJ max | 150 °C - enables operation in engine-bay or under-hood environments with validated thermal margin |
| CJ | 80 pF @ 4 V - contributes predictable capacitive loading in snubber networks and gate-drive isolation |
Pinout & Package
Package: DO-214AB (SMC), molded epoxy case meeting UL 94V-0, matte tin-plated leads, polarity indicated by cathode band, weight ≈ 0.210 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EJH03-M3/5BT | Same DO-214AB package, 300 V VRRM, but 1.3 V VF max at 3 A and 75 ns trr | Higher conduction loss and slower recovery limit use in >200 kHz designs | Select when legacy layout reuse is critical and efficiency targets allow +0.3 V VF penalty |
| ON Semiconductor MUR330 | DO-201AD package (larger), 300 V VRRM, 1.3 V VF, 75 ns trr, no AEC-Q101 qualification | Not suitable for automotive under-hood use; requires larger PCB footprint | Choose only for cost-sensitive industrial non-automotive applications with relaxed reliability requirements |
Compared with VS-3EJH03-M3/5BT and MUR330, the HS3FH delivers lower forward drop and faster recovery in an AEC-Q101-qualified SMC package - making it optimal for space- and efficiency-constrained automotive power stages where thermal and EMI margins are tight.

FAQ
What is the maximum junction temperature rating for HS3FH?
The HS3FH has a maximum junction temperature (TJ) of +150 °C, validated per JEDEC JESD22-A104. This rating allows continuous operation in under-hood automotive environments when mounted on ≥1 in² 2-oz copper with thermal vias. Derating begins above 75 °C ambient, and the device must not exceed 150 °C under any steady-state or transient condition. The HS3FH datasheet specifies this limit across all operating modes, including repetitive surge events.
Is HS3FH suitable for use in AEC-Q101-compliant automotive designs?
Yes, the HS3FH is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TC, and UHAST. Its glass-passivated junction, moisture sensitivity level 1, and UL 94V-0 molding compound meet automotive reliability requirements. The HS3FH is used in production automotive DC-DC modules and LED drivers where failure modes must be mitigated per ISO 26262 ASIL-B functional safety frameworks.
What is the reverse recovery time (trr) specification for HS3FH?
The HS3FH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC JESD28-C. This value is confirmed across the full temperature range (−55 °C to +125 °C) and supports switching frequencies up to 500 kHz in hard-switched topologies. The HS3FH's trr is 25 ns faster than comparable 300 V rectifiers such as the MUR330.
Does HS3FH have halogen-free and RoHS compliance documentation?
Yes, the HS3FH complies with IEC 61249-2-21 for halogen-free materials and meets EU RoHS Directive 2011/65/EU. Certificate of Compliance (CoC) and material declarations are available from Taiwan Semiconductor upon request. The HS3FH uses bromine-free flame retardants in its DO-214AB molding compound and contains <900 ppm bromine and <900 ppm chlorine by weight - fully documented in TSC's IMDS submission ID 1287432.
What is the marking code printed on the HS3FH device body?
The HS3FH is marked with "HS3F" on the device body, followed by green compound indicator "G", date code (e.g., "2426" for week 26 of 2024), and factory code "F". This marking aligns with the ordering code HS3FH and is visible under 10× magnification. The cathode band is located adjacent to the marking, confirming terminal polarity. No additional symbols or logos appear on the HS3FH top surface.
