Product details
Overview
BYG23MH from Taiwan Semiconductor is a 1.5A, 1000V high-efficiency surface-mount rectifier diode in DO-214AC (SMA) package, featuring AEC-Q101 qualification, 50A non-repetitive surge current rating, and 65ns reverse recovery time. It serves as a fast-switching freewheeling/clamping diode in automotive power supplies and industrial switching converters.
For engineers reviewing the BYG23MH datasheet, BYG23MH pinout, BYG23MH application, or BYG23MH equivalent, key selection criteria include avalanche energy rating (30 mJ), junction-to-ambient thermal resistance (70°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
BYG23MH is a single-die, glass-passivated silicon rectifier optimized for high-voltage, high-speed switching. Its 1000V repetitive peak reverse voltage and 700V RMS reverse voltage support operation in 800V-class DC bus systems, while its 65ns trr enables use in 100–500 kHz SMPS topologies.
The device delivers 30 mJ non-repetitive avalanche energy under inductive turn-off conditions (IBR,R = 1.23A), enabling robust clamping without external snubbers. Its 15 pF junction capacitance at 4V reverse bias minimizes switching losses in high-frequency resonant circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600V VRRM, 1A IF, 50ns trr, TO-277 package | Limited to ≤600V systems; lower surge rating (30A) | Select when lower voltage rating suffices and faster recovery is prioritized over avalanche ruggedness |
| ES1J-M3/5AT | 600V VRRM, 1A IF, 35ns trr, DO-214AC package | No AEC-Q101 qualification; no specified avalanche energy | Choose for cost-sensitive consumer power supplies where automotive qualification is unnecessary |
Compared with STTH1L06S and ES1J-M3/5AT, BYG23MH uniquely combines 1000V rating, AEC-Q101 qualification, and 30 mJ avalanche capability-making it the only option among the three validated for 800V automotive power conversion with inductive fault tolerance.

FAQ
What is the maximum junction temperature rating for BYG23MH?
BYG23MH has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures exceed 105°C. Derating curves confirm 1.5A continuous current is maintainable up to 110°C ambient with standard PCB copper area.
Is BYG23MH suitable for automotive applications?
Yes, BYG23MH is AEC-Q101 qualified and explicitly designed for automotive power systems. Its glass-passivated junction, MSL Level 1 rating, halogen-free construction, and 30 mJ avalanche energy make it appropriate for engine control units, DC-DC converters, and battery disconnect modules where reliability under thermal cycling and electrical stress is mandatory.
What does the marking code 'BYG23M' on the BYG23MH device indicate?
The marking code 'BYG23M' on the BYG23MH device is the laser-etched top-side identifier per ordering specification; it omits the final 'H' but corresponds exclusively to the BYG23MH variant. This marking, combined with the green compound (G) and date code (YW), enables full traceability to the A2102 version and DO-214AC packaging confirmed in TSC's official documentation.
How does the 65ns reverse recovery time of BYG23MH impact converter efficiency?
The 65ns reverse recovery time (trr) of BYG23MH reduces switching losses in hard-switched topologies, directly improving efficiency at 100–300 kHz. Measured under IF = 0.5A, IR = 1.0A, Irr = 0.25A conditions, this trr value limits tail current duration, minimizing overlap loss in synchronous rectifier replacement scenarios and enabling higher frequency operation without excessive EMI.
What is the avalanche energy rating of BYG23MH and how is it tested?
BYG23MH has a non-repetitive avalanche energy rating (ERSM) of 30 mJ, measured under inductive turn-off conditions with IBR,R = 1.23A. This rating is verified per JEDEC JESD24-11 methodology and enables safe clamping of voltage spikes in flyback, boost, and LLC converters without external protection components-critical for space-constrained automotive and industrial designs.
