Product details
Overview
BA159GHB0G from Taiwan Semiconductor is a 1A, 1000V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 250 ns reverse recovery time, 1.2 V max forward voltage at 1 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-efficiency DC-DC converters operating under repetitive surge conditions.
For engineers reviewing the BA159GHB0G datasheet, BA159GHB0G pinout, BA159GHB0G application, or BA159GHB0G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (60 °C/W), junction temperature range (–55 to +150 °C), surge current capability (30 A), and RoHS/halogen-free compliance for automotive and industrial power supplies.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for switching-mode power conversion. Its fast recovery (250 ns) enables reduced switching losses in high-frequency topologies, while the 1000 V VRRM supports wide-input-range offline and industrial DC-DC designs.
The DO-204AL package provides mechanical robustness and solderability per J-STD-002, with pure tin-plated leads and UL 94V-0 molding compound. Polarity is marked by a cathode band, and the device meets JESD201 Class 2 whisker resistance requirements.
Key Specifications

| VRRM | 1000 V - Withstands up to 1000 V repetitive reverse voltage without breakdown, enabling use in 800 V DC bus systems. |
| IF | 1 A continuous - Rated average forward current at 75 °C ambient, suitable for low-to-medium power rectification stages. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms half-sine), supports inrush and transient overload handling. |
| trr | 250 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation up to ~200 kHz switching frequencies. |
| VF (max) | 1.2 V @ 1 A, 25 °C - Low conduction loss improves system efficiency and reduces thermal stress in compact layouts. |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance defines heatsinking requirement for sustained 1 A operation at elevated ambient temperatures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; 150 ns trr; TO-220AC package; higher RθJA (~50 °C/W but larger footprint). | Not AEC-Q101 qualified; suited for industrial benchtop supplies, not automotive under-hood use. | Select when lower trr is prioritized over automotive qualification and board space is unconstrained. |
| ON Semi MUR110E | 1 A / 1000 V; 75 ns trr; DO-41 package; AEC-Q101 not claimed; IFSM = 25 A (vs. 30 A). | Lacks formal automotive qualification; acceptable for commercial-grade telecom or computing PSUs. | Choose where ultra-fast recovery is critical and AEC-Q101 is not mandated. |
Compared with STTH1R06 and MUR110E, BA159GHB0G uniquely combines 1000 V rating, AEC-Q101 qualification, 250 ns trr, and DO-41 form factor-making it optimal for space-constrained, thermally demanding automotive and industrial rectification where reliability and regulatory compliance are mandatory.

FAQ
What is the peak repetitive reverse voltage rating for BA159GHB0G?
The BA159GHB0G has a peak repetitive reverse voltage (VRRM) rating of 1000 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2106). It defines the maximum reverse voltage the device can block repeatedly without breakdown, making BA159GHB0G suitable for high-voltage DC bus applications such as 800 V systems and offline SMPS front ends.
Is BA159GHB0G AEC-Q101 qualified, and what does the 'H' suffix indicate?
Yes, BA159GHB0G is AEC-Q101 qualified-the 'H' in the ordering code explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering information table. This certification validates the device for automotive applications including temperature cycling, humidity bias, and mechanical shock testing. BA159GHB0G is intended for use in engine control, body electronics, and ADAS subsystems where reliability under harsh environmental conditions is required.
What is the reverse recovery time (trr) of BA159GHB0G, and how is it measured?
The reverse recovery time (trr) of BA159GHB0G is 250 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Specifications table. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state, directly impacting switching loss and EMI in high-frequency converters. BA159GHB0G's trr is higher than BA157G (150 ns) due to its higher VRRM design trade-off.
What package type and lead finish does BA159GHB0G use?
BA159GHB0G uses the DO-204AL (DO-41) axial-leaded package with pure tin-plated leads compliant with J-STD-002 solderability standards. The molding compound meets UL 94V-0 flammability rating, and polarity is indicated by a cathode band. This package supports manual and automated through-hole assembly and is rated for 0.330 g weight and JESD201 Class 2 whisker resistance.
How does the thermal performance of BA159GHB0G affect PCB layout decisions?
BA159GHB0G has a junction-to-ambient thermal resistance (RθJA) of 60 °C/W in standard JEDEC test conditions. This means that at 1 A continuous forward current, the junction temperature rise above ambient can exceed safe limits without adequate copper pour or airflow. Engineers should allocate ≥ 100 mm² of 2 oz copper connected to both leads and avoid routing heat-sensitive components nearby to maintain TJ ≤ 150 °C in enclosed enclosures or high-ambient environments.
