Product details
Overview
HS3ABH from Taiwan Semiconductor is a 3A, 50V AEC-Q101-qualified surface-mount Schottky rectifier in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A/25°C, 100A surge rating, and 50ns reverse recovery time - deployed in automotive lighting and DC-DC converter freewheeling paths.
For engineers reviewing the HS3ABH datasheet, HS3ABH pinout, HS3ABH application, or HS3ABH equivalent, key selection criteria include its 50V VRRM rating, low-profile SMB package compatibility with automated placement, AEC-Q101 qualification for under-hood use, and verified thermal resistance of 60°C/W junction-to-ambient.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of 150°C and supports continuous forward current up to 3A at 25°C ambient. Its glass-passivated junction ensures reliability in humid environments, while J-STD-020 Level 1 moisture sensitivity enables standard reflow without baking.
The device delivers fast switching performance with 50ns reverse recovery time and 80pF junction capacitance at 1MHz/4V, enabling high-frequency operation in snubber and freewheeling circuits where low conduction loss and minimal stored charge are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in 12–24V automotive systems. |
| IF | 3 A - Continuous forward current rating at 25°C; determines steady-state power handling in DC-DC output stages. |
| VF @ 3A | ≤1.0 V - Forward voltage drop at rated current; directly impacts conduction loss and thermal rise in high-efficiency designs. |
| IFSM | 100 A - Non-repetitive surge current capacity; supports inrush and transient overload tolerance in automotive power rails. |
| trr | 50 ns - Reverse recovery time; enables stable operation at switching frequencies up to ~1 MHz in flyback and buck converters. |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements when operating near 3A continuous load. |
| CJ | 80 pF - Junction capacitance at 1MHz/4V; influences high-frequency noise coupling and EMI filter design in switching nodes. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode indicated by band, UL 94V-0 rated compound, weight ≈0.093g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); requires low-inductance layout to minimize ringing. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or ground return; must sustain full VRRM during off-state in high-side configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Glass-passivated junction | Provides hermetic protection against moisture ingress and contamination, extending operational life in harsh automotive environments. |
| Low profile SMB package | Enables compact PCB layouts and compatibility with standard SMT pick-and-place equipment without height interference. |
| J-STD-020 Level 1 MSL | Allows indefinite storage and standard reflow soldering without pre-baking, reducing manufacturing overhead and process risk. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives, supporting environmental compliance for global OEM automotive supply chains. |
Applications
| Automotive Lighting | DC-DC Converter Freewheeling |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH05-M3/57T | Same DO-214AA package, 3A/50V rating, but VF = 0.52V typ (lower), trr not specified; no AEC-Q101 claim. | Preferred in non-automotive industrial DC-DC where ultra-low VF dominates over qualification requirements. | Select when lowest conduction loss is critical and automotive qualification is not required. |
| ON Semiconductor SB350-E3/57T | DO-214AA, 3A/50V, VF = 0.52V typ, trr = 35ns (faster), but only AEC-Q200 qualified (passive component level), not AEC-Q101. | Suitable for cost-sensitive consumer power supplies where faster switching matters more than semiconductor-level automotive validation. | Choose for higher-frequency (>500kHz) designs needing sub-40ns trr, accepting reduced automotive validation scope. |
Compared with VS-3EYH05-M3/57T and SB350-E3/57T, HS3ABH trades slightly higher VF for full AEC-Q101 qualification and guaranteed 50ns trr - making it the preferred choice for production automotive modules requiring certified reliability and defined switching behavior.

FAQ
What is the maximum junction temperature rating for HS3ABH?
The HS3ABH has a maximum junction temperature (TJ MAX) of +150°C, validated per absolute maximum ratings in the official datasheet. This allows reliable operation in under-hood automotive environments where ambient temperatures may reach 125°C, provided thermal design maintains junction temperature below this limit. The 60°C/W RθJA value helps calculate allowable power dissipation under specific board conditions.
Is HS3ABH suitable for use in AEC-Q101-compliant automotive designs?
Yes, HS3ABH is explicitly AEC-Q101 qualified per the manufacturer's documentation, covering stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This makes HS3ABH appropriate for production automotive applications such as lighting drivers and body control modules where semiconductor-level reliability validation is mandatory.
What does the marking code 'HS3AB' on the HS3ABH device indicate?
The marking code 'HS3AB' on the HS3ABH identifies the device family (HS), forward current rating (3A), and voltage grade (50V). Per the ordering information table, 'AB' corresponds to the 50V VRRM variant within the HS3x BH series. The 'H' suffix denotes the DO-214AA (SMB) package, and the full part number HS3ABH is required for unambiguous ordering and traceability.
How does the forward voltage of HS3ABH compare across temperature and current conditions?
HS3ABH specifies ≤1.0V VF at IF = 3A and TJ = 25°C (pulse test, PW = 0.3ms). VF increases with junction temperature and current - typical curves show ~1.15V at 100°C and 3A. Designers must consult Figure 4 (Typical Forward Characteristics) in the datasheet to model conduction loss across operating conditions, especially in thermally constrained automotive modules.
Can HS3ABH be used as a direct replacement for other HS3x BH variants like HS3BBH or HS3DBH?
No - HS3ABH is rated for 50V VRRM, while HS3BBH (100V) and HS3DBH (200V) have higher blocking voltages and different forward voltage characteristics. Substituting HS3ABH in a 100V+ circuit risks reverse breakdown. Voltage grade must match system requirements; only parts sharing identical 'x' letter in HS3xBH nomenclature (e.g., HS3ABH, HS3ABM) are functionally aligned within the same voltage bin.
