Product details
Overview
BA159G 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 5 µA max reverse leakage at 25°C. It serves as a primary output rectifier in high-efficiency DC-DC converters and switching inverters operating up to 150°C junction temperature.
For engineers reviewing the BA159G datasheet, BA159G pinout, BA159G application, or BA159G equivalent, key selection criteria include repetitive peak reverse voltage (1000 V), surge current capability (30 A), thermal resistance (60 °C/W), RoHS/halogen-free compliance, and AEC-Q101 qualification availability in variant BA159GH.
Technical Context
The BA159G employs a glass-passivated single-die silicon junction optimized for fast recovery in high-frequency switching topologies. Its 250 ns trr enables reduced switching losses in SMPS designs operating above 50 kHz, while the 1000 V VRRM rating supports input-stage rectification in industrial AC-DC front-ends and photovoltaic string inverters.
Thermal performance is defined by a 60 °C/W junction-to-ambient resistance under standard PCB mounting conditions, and its pure tin-plated leads meet J-STD-002 solderability with JESD201 Class 2 whisker resistance - critical for automotive and long-life industrial deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports rectification of 700 V RMS inputs without breakdown margin violation |
| IF | 1 A continuous - suitable for low-to-medium power DC-DC outputs up to ~15 W at 12 V |
| trr | 250 ns - enables efficient operation in 100–500 kHz switching converters |
| VF (max) | 1.2 V @ 1 A, 25°C - limits conduction loss to ≤1.2 W per device at full load |
| IFSM | 30 A @ 8.3 ms - withstands cold-start surges and transient overloads in offline supplies |
| RθJA | 60 °C/W - requires minimal copper area for thermal management in compact layouts |
| IR (max) | 5 µA @ 25°C - ensures low standby leakage in battery-backed or energy-harvesting systems |

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 | 1 A, 600 V VRRM; 150 ns trr; TO-220AC package | Limited to ≤600 V systems; higher thermal mass but requires heatsink for >0.5 A continuous | Select when lower trr is prioritized over voltage rating and board space allows TO-220 footprint |
| ON Semi MUR110 | 1 A, 1000 V VRRM; 75 ns trr; DO-41 package; higher VF (1.7 V) | Superior speed but higher conduction loss; not AEC-Q101 qualified | Choose where ultra-fast recovery dominates efficiency trade-off and automotive qualification is not required |
Compared with STTH1R06 and MUR110, the BA159G uniquely balances 1000 V rating, 250 ns recovery, DO-41 form factor, and AEC-Q101 availability - making it optimal for space-constrained, high-reliability industrial and automotive auxiliary power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for BA159G?
The BA159G has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per Taiwan Semiconductor's official datasheet Version I2106. This rating ensures safe operation under worst-case transient conditions in 700 V RMS AC systems and high-voltage DC bus applications. The BA159G achieves this while maintaining a compact DO-41 package and 250 ns reverse recovery time - distinguishing it from lower-voltage variants like BA157G (400 V) and BA158G (600 V).
Is BA159G suitable for automotive applications?
The standard BA159G is not AEC-Q101 qualified, but its variant BA159GH is explicitly certified to AEC-Q101. BA159G shares identical electrical and thermal specifications with BA159GH - including 1000 V VRRM, 250 ns trr, and 150°C TJ(max) - making it suitable for non-automotive industrial use. For automotive deployment, BA159GH must be specified to meet stress-test and lifetime validation requirements.
What is the forward voltage drop (VF) of BA159G at rated current?
The BA159G exhibits a maximum forward voltage drop (VF) of 1.2 V at 1 A forward current and 25°C junction temperature, as confirmed in the Electrical Specifications table of the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures (e.g., 125°C), VF decreases slightly, supporting stable conduction in thermally stressed environments.
Does BA159G have a defined thermal resistance specification?
Yes, the BA159G has a specified junction-to-ambient thermal resistance (RθJA) of 60 °C/W under standard test conditions on FR-4 PCB with 1-inch² copper pad. This value enables accurate thermal design for natural-convection cooling in compact power supplies. No separate RθJC is published, as the DO-41 package lacks a dedicated thermal pad - heat dissipation relies entirely on lead conduction and PCB copper area.
What packaging options are available for BA159G?
BA159G is offered in two standard packaging formats: 5,000 units per tape-and-reel (ordering code BA159G) and 3,000 units per ammo box (ordering code BA159G A0G). Both use the DO-204AL (DO-41) package with green molding compound and cathode-band polarity marking. The "A0G" suffix denotes the ammo box configuration only - electrical, thermal, and mechanical specs are identical across both pack types.
