Product details
Overview
BYG20DH from Taiwan Semiconductor is a 1.5A, 200V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AC (SMA) package, featuring 75ns reverse recovery time (trr), 30A peak surge current (IFSM), and AEC-Q101 qualification for automotive-grade reliability-used in DC-DC converters and freewheeling paths.
For engineers reviewing the BYG20DH datasheet, BYG20DH pinout, BYG20DH application, or BYG20DH equivalent, key selection criteria include its 200V VRRM, 1.4V max forward voltage at 1.5A, 1µA max reverse leakage at 25°C, AEC-Q101 qualification, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
The BYG20DH employs a glass-passivated silicon junction to achieve fast switching (trr = 75ns typ.) and high surge robustness (IFSM = 30A, 8.3ms half-sine). Its thermal design targets 25°C/W junction-to-lead resistance (RθJL) when mounted on a 5mm × 5mm Cu pad.
It operates across -55°C to +150°C junction temperature range, supports 100% lead-free matte tin plating per J-STD-002, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for automotive PCB environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in snubber or freewheeling circuits |
| IF | 1.5 A continuous - Rated average forward current under specified thermal conditions; determines power dissipation in DC-DC output stages |
| trr | 75 ns - Reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables high-frequency switching efficiency |
| IFSM | 30 A - Peak non-repetitive surge current capability; withstands inductive turn-off transients in automotive loads |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments |
| VF max | 1.4 V at IF = 1.5A - Forward voltage drop directly impacts conduction loss and thermal design margin |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance on standard 5mm × 5mm Cu pad; enables accurate thermal modeling for layout |

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 | VRRM = 600V, IF = 1A, trr = 60ns, DO-214AC | Higher voltage rating but lower current; faster recovery | Select when system requires >200V blocking with tighter trr budget, accepting reduced IF rating |
| ON Semi MUR120 | VRRM = 200V, IF = 1A, trr = 75ns, DO-41 axial | Same VRRM/trr, but axial leaded package and lower IF | Choose only for through-hole prototyping or legacy board reuse; not suitable for automated SMT production |
Compared with STTH1L06S and MUR120, the BYG20DH uniquely balances 200V VRRM, 1.5A IF, 75ns trr, and AEC-Q101 qualification in a surface-mount DO-214AC package-making it optimal for volume automotive SMT designs requiring both reliability and thermal efficiency.

FAQ
What is the maximum junction temperature rating for BYG20DH?
The BYG20DH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows reliable operation in under-hood automotive environments and high-power-density DC-DC converters. Thermal derating must be applied above ambient temperatures where RθJA = 100°C/W applies. The BYG20DH maintains stable electrical performance within this full -55°C to +150°C range.
Is BYG20DH suitable for automotive applications?
Yes, the BYG20DH is explicitly AEC-Q101 qualified per its official Taiwan Semiconductor documentation, confirming compliance with stress tests for temperature cycling, humidity, and mechanical shock required for automotive electronics. It is deployed in automotive LED lighting, DC-DC converters, and actuator freewheeling circuits. The BYG20DH's glass passivation, halogen-free construction, and DO-214AC SMT package further support automotive manufacturing and field reliability requirements.
What does the 'D' in BYG20DH indicate?
The 'D' in BYG20DH specifies the 200V repetitive peak reverse voltage (VRRM) rating, as confirmed in the ordering code table where BYG20DH maps to VRRM = 200V, BYG20GH to 400V, and BYG20JH to 600V. The marking code physically printed on the device is 'BYG20D'. This letter-based suffix is part of Taiwan Semiconductor's standardized voltage grading system for the BYG20xH family.
What is the reverse recovery time (trr) of BYG20DH and how is it measured?
The BYG20DH has a typical reverse recovery time (trr) of 75ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications section of the Taiwan Semiconductor datasheet. This parameter reflects the diode's ability to transition from forward conduction to reverse blocking, directly impacting switching loss in high-frequency power supplies. The BYG20DH's 75ns trr supports efficient operation in DC-DC converters up to several hundred kHz.
Does BYG20DH have moisture sensitivity level (MSL) certification?
Yes, the BYG20DH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This is confirmed in the Mechanical Data section of the official Taiwan Semiconductor datasheet. The MSL Level 1 rating simplifies SMT line integration and eliminates moisture-related popcorning risk-critical for high-yield automotive electronics manufacturing. The BYG20DH's packaging and passivation ensure robustness under standard reflow profiles.
