Product details
Overview
HS2BAH from Taiwan Semiconductor is a 1.5A, 100V AEC-Q101-qualified surface-mount fast recovery rectifier in DO-214AC (SMA) package, featuring 1.0V forward voltage at 1.5A, 50ns reverse recovery time, and 5µA reverse leakage at 25°C - deployed in automotive lighting and DC-DC snubber circuits.
For engineers reviewing the HS2BAH datasheet, HS2BAH pinout, HS2BAH application, or HS2BAH equivalent, key selection criteria include peak repetitive reverse voltage (100V), thermal resistance (80°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 HS2BAH employs a glass-passivated single-die silicon junction optimized for fast switching and low conduction loss. Its 50ns trr and 1.0V VF at rated current enable high-efficiency operation in high-frequency DC-DC converters and freewheeling paths.
Designed for automotive-grade reliability, the device meets AEC-Q101 stress test requirements and features moisture sensitivity level 1 (J-STD-020), matte tin-plated leads per J-STD-002, and UL 94V-0 mold compound - supporting automated SMT placement without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in snubber and freewheeling applications |
| IF | 1.5 A - continuous average forward current; determines thermal design margin in 12V/24V automotive power rails |
| VF @ 1.5A | 1.0 V - forward voltage drop at rated current; directly impacts conduction loss and thermal rise in compact layouts |
| trr | 50 ns - reverse recovery time; enables stable operation up to ~2 MHz switching frequencies in DC-DC topologies |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance; sets minimum copper area requirement for 1.5A continuous operation |
| IR @ 25°C | 5 µA - reverse leakage current at rated VR; ensures low standby power loss in battery-coupled systems |
| TJ Range | −55°C to +150°C - operational junction temperature range; supports under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 1A rating, 600V VRRM, VF = 1.15V @ 1A, trr = 50ns, same DO-214AC package | Higher voltage capability but lower current; suited for 48V systems with lower load demand | Select when system requires >100V blocking with no increase in IF |
| MBR1100 | 1A Schottky, 100V VRRM, VF = 0.82V @ 1A, no reverse recovery (trr = N/A), higher IR (~500µA) | Lower conduction loss but elevated leakage; unsuitable for high-temp battery disconnect scenarios | Prefer where efficiency dominates over leakage-critical standby modes |
Compared with STTH1L06S and MBR1100, the HS2BAH uniquely balances 1.5A current capacity, 100V rating, 1.0V VF, and 5µA IR - making it optimal for 12V/24V automotive power stages requiring both robustness and low leakage.

FAQ
What is the peak repetitive reverse voltage rating for HS2BAH?
The HS2BAH has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2102). It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding this rating risks irreversible junction failure.
Is HS2BAH suitable for automotive applications?
Yes, HS2BAH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and body control modules. Its glass-passivated junction, −55°C to +150°C junction temperature range, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 all meet automotive manufacturing and reliability requirements defined in the datasheet.
What is the forward voltage drop of HS2BAH at its rated current?
The forward voltage (VF) of HS2BAH is 1.0 V at 1.5 A and 25°C junction temperature, as confirmed in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss - critical for thermal design in space-constrained automotive PCBs where HS2BAH is commonly deployed.
Does HS2BAH have a defined reverse recovery time?
Yes, HS2BAH has a maximum reverse recovery time (trr) of 50 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is documented in the Electrical Specifications section and confirms its classification as a fast recovery rectifier - essential for minimizing switching losses in high-frequency DC-DC converters using HS2BAH.
What package type does HS2BAH use, and what are its key mechanical attributes?
HS2BAH uses the DO-214AC (SMA) surface-mount package. Key mechanical attributes include a low-profile outline, UL 94V-0 flammability-rated molding compound, matte tin-plated leads compliant with J-STD-002, cathode band polarity marking, and approximate weight of 0.060 g - all verified in the Mechanical Data section of the Taiwan Semiconductor datasheet.
