Product details
Overview
BA158G from Taiwan Semiconductor is a 1A, 600V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150 ns reverse recovery time, 1.2 V max forward voltage at 1 A, and 30 A surge current capability. It serves as a primary output rectifier in switching-mode power supplies for industrial and automotive DC-DC converters.
For engineers reviewing the BA158G datasheet, BA158G pinout, BA158G application, or BA158G equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, AEC-Q101 qualification option (BA158GH), thermal resistance of 60 °C/W, and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
The BA158G employs a glass-passivated single-die silicon junction optimized for fast recovery (trr ≤ 150 ns) and low conduction loss. Its 600 V VRRM rating targets mid-voltage switching applications where efficiency and thermal management are critical, such as auxiliary rails in 24 V–48 V systems.
Designed for operation from –55 °C to +150 °C junction temperature, it delivers stable reverse leakage (< 5 µA at 25 °C, < 100 µA at 125 °C) and exhibits 15 pF junction capacitance at 4 V reverse bias-enabling predictable high-frequency switching behavior in flyback and forward converter topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 420 V RMS in bridge or single-phase rectification |
| IF | 1 A continuous - suitable for low-to-medium power outputs (e.g., ≤15 W at 12 V) |
| IFSM | 30 A (8.3 ms half-sine) - withstands startup surges and transient overloads without failure |
| trr | ≤150 ns - reduces switching losses and EMI in 50–500 kHz SMPS designs |
| VF | ≤1.2 V @ 1 A, 25 °C - limits conduction loss to ≤1.2 W at full load, easing thermal design |
| RθJA | 60 °C/W - requires ≤75 °C ambient or heatsinking for reliable 1 A operation at 150 °C TJ |
| IR | ≤5 µA @ 25 °C - ensures minimal standby leakage in energy-sensitive applications |

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; trr = 100 ns (faster); VF = 1.15 V typ; TO-220AC package | Requires PCB footprint change and heatsink; better for higher ambient or forced-air cooling | Select when lower VF and faster trr justify larger package and thermal management overhead |
| ON Semi MUR106 | 1 A / 600 V; trr = 75 ns; VF = 1.15 V max; DO-41 package; no AEC-Q101 variant | Higher performance in same footprint but lacks automotive qualification path | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with STTH1R06 and MUR106, the BA158G offers AEC-Q101 qualification readiness (via BA158GH), identical DO-41 footprint, and balanced trade-offs between recovery speed, forward loss, and qualification coverage-making it optimal for space-constrained automotive and industrial power supplies requiring proven reliability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the BA158G?
The BA158G has a maximum repetitive peak reverse voltage (VRRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2106). The BA158G is part of a family where BA157G = 400 V, BA158G = 600 V, and BA159G = 1000 V. This 600 V rating makes BA158G appropriate for use in 24 V and 48 V input power systems with adequate derating.
Is the BA158G AEC-Q101 qualified?
The standard BA158G is not AEC-Q101 qualified, but the variant BA158GH is explicitly listed as AEC-Q101 qualified in the Ordering Information section of the datasheet. The "H" suffix denotes qualification per AEC-Q101 stress test requirements. For automotive applications requiring qualification evidence, BA158GH-not BA158G-must be specified and sourced.
What is the reverse recovery time (trr) specification for the BA158G?
The BA158G has a maximum reverse recovery time (trr) of 150 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is documented in the Electrical Specifications table and distinguishes BA158G from BA157G (also 150 ns) and BA159G (250 ns). The 150 ns trr supports efficient operation in switching power supplies operating up to several hundred kHz.
What package type does the BA158G use, and what are its key mechanical features?
The BA158G uses the DO-204AL (DO-41) axial-leaded package. Key mechanical features include glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002, UL 94V-0 flammability-rated molding compound, and cathode polarity indicated by a band. Its approximate weight is 0.330 g, and it meets JESD201 Class 2 whisker testing requirements.
How does the BA158G compare to the BA157G and BA159G in terms of voltage rating and recovery time?
The BA158G shares the same 150 ns maximum trr as the BA157G but differs in VRRM: BA157G = 400 V, BA158G = 600 V, BA159G = 1000 V. BA159G has a slower 250 ns trr. All three share identical IF = 1 A, IFSM = 30 A, and DO-41 packaging. Selection depends strictly on required blocking voltage and acceptable recovery speed for the target topology and frequency.
