Product details
Overview
ABS20T1M from Diodes Incorporated is a 2A surface-mount fast recovery bridge rectifier in SOPA-4 (Type WX) package, rated for 1000V repetitive peak reverse voltage (VRRM), 1.3V max forward voltage at 2A, and 500ns reverse recovery time (trr). It serves as an AC-to-DC conversion element in offline power supplies, LED drivers, and industrial control power stages.
For engineers reviewing the ABS20T1M datasheet, ABS20T1M pinout, ABS20T1M application, or ABS20T1M equivalent, key selection criteria include VRRM margin for surge immunity, trr for high-frequency switching efficiency, thermal resistance (RθJA = 40°C/W), and RoHS-compliant lead-free construction for automotive and industrial compliance.
Technical Context
This bridge rectifier integrates four fast-recovery diodes in a single SOPA-4 package with glass-passivated die construction, enabling stable operation up to +150°C junction temperature. Its 500ns trr and low 27pF junction capacitance support switching frequencies up to several hundred kHz in flyback and forward converters.
The device delivers 2A average forward current without heatsink at TC = +120°C and supports 60A non-repetitive surge (8.3ms half-sine) at TJ = +25°C - critical for handling line transients in universal-input AC/DC designs.

| IR Max | 5 µA @ 1000V, 25°C - Ensures minimal leakage in high-impedance hold-up circuits |
| RθJA | 40 °C/W - Requires ≥30mm × 30mm 2oz copper pad for thermal management at full load |
| Package | SOPA-4 (Type WX) - Surface-mount footprint compatible with standard reflow profiles and automated assembly |
Pinout & Package

Applications
| Industrial Power Supplies | LED Driver Front-End |
|---|---|
Use Scenario: AC/DC conversion stage in DIN-rail mounted 24V/48V industrial PSUs handling 100–240VAC input. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC line to unregulated DC bus prior to PFC and DC/DC stages. Use Value: 1000V VRRM ensures robustness against 4kV line surges per IEC 61000-4-5; 2A IF(AV) supports up to 48W output with margin. | Use Scenario: Input rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: AC input conditioning block delivering ripple-reduced DC to buck or flyback controller ICs. Use Value: 500ns trr minimizes switching losses during high-frequency PWM dimming; low VF reduces thermal stress on heatsink-limited enclosures. |
| Appliance Control Boards | Smart Meter Power Conversion |
Use Scenario: Auxiliary power supply for microcontroller and sensor circuitry in washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Primary-side rectifier feeding isolated flyback converter powering logic and communication interfaces. Use Value: SOPA-4 footprint enables compact board area usage; RθJA = 40°C/W allows operation without dedicated heatsink in sealed enclosures. | Use Scenario: Mains-powered energy meter with integrated PLC or RF communication requiring reliable, long-life AC input stage. IC Role / Device Role / Timing Role: Input bridge rectifier supplying isolated DC for metrology ICs and communication SoCs. Use Value: -55°C to +150°C operating range ensures functionality across outdoor temperature extremes; 5µA IR at 25°C preserves accuracy in high-impedance voltage divider networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K | Through-hole GBU package; higher RθJA (~50°C/W); VF = 1.1V @ 2A | Requires PCB through-hole mounting and larger board area; better conduction loss but worse thermal performance | Prefer when manual assembly or legacy board reuse is required; avoid in space-constrained SMT-only designs |
| ABS20M | Same SOPA-4 package; identical VRRM/IF but slower trr = 1.5µs; VF = 1.2V @ 2A | Lower cost but unsuitable for >100kHz switching due to higher reverse recovery charge | Select only for low-frequency linear or quasi-resonant supplies where trr impact is negligible |
Compared with ABS20M and GBU2K, ABS20T1M uniquely balances fast recovery (500ns), SMT compatibility, and 1000V rating - making it optimal for modern compact, high-efficiency AC/DC converters where layout density and switching frequency matter.

FAQ
What is the maximum junction temperature for ABS20T1M?
The ABS20T1M has an operating junction temperature range of -55°C to +150°C, verified per its datasheet maximum ratings table. This rating applies under specified thermal conditions, including use of recommended PCB copper area (30mm × 30mm, 2oz) and ambient temperature limits. Derating curves confirm 2A IF(AV) is sustainable at TC = +120°C without heatsink.
Is ABS20T1M suitable for automotive applications?
ABS20T1M is not AEC-Q101 qualified out-of-the-box. While it meets RoHS 3 and halogen-free requirements, Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - meaning standard ABS20T1M should not be used in safety-critical automotive systems without formal qualification and validation by the customer.
How does the SOPA-4 package differ from standard SOIC-4?
SOPA-4 (Type WX) is a proprietary Diodes package with wider lead pitch (e = 3.8–4.2mm) and longer gull-wing leads than standard SOIC-4 (e = 1.27mm). Its dimensions (D = 4.85–5.25mm, E = 6.4–6.8mm) and internal leadframe geometry are optimized for higher current handling and thermal dissipation - confirmed by its 2A rating and RθJA = 40°C/W specification.
What is the typical junction capacitance of ABS20T1M?
The typical junction capacitance (CT) of ABS20T1M is 27pF, measured at 1.0MHz with 4.0V DC reverse bias, as stated in the Electrical Characteristics table. This value is relevant for EMI filter design and high-frequency switching behavior, particularly in flyback converters where diode capacitance interacts with transformer leakage inductance.
