Product details
Overview
RABS20M from Diodes Incorporated is a 2.0A surface-mount fast recovery bridge rectifier rated for 1000V peak repetitive reverse voltage, with 1.3V forward voltage at 2A and 1μA leakage current at 1000V/25°C; it delivers low EMI full-wave rectification in wireless charging power stages and compact AC/DC adapters.
For engineers reviewing the RABS20M datasheet, RABS20M pinout, RABS20M application, or RABS20M equivalent, key selection criteria include its SOPA-4 package thermal resistance (RθJL = 15°C/W), 250ns reverse recovery time, 60A non-repetitive surge rating, and UL recognition (E364304) for safety-critical power conversion designs.
Technical Context
The RABS20M integrates four fast recovery diodes in a single-phase bridge configuration with glass-passivated junctions, enabling high-efficiency AC-to-DC conversion under capacitive-load conditions (with 20% current derating). Its 27pF junction capacitance and 250ns tRR support stable operation in high-frequency switching environments up to several hundred kHz.
Designed for surface-mount assembly on FR-4 PCBs with 2oz copper pads, the device maintains thermal stability via low junction-to-lead resistance (15°C/W) and operates across –55°C to +150°C, supporting automotive-grade ambient requirements when paired with appropriate system-level qualification.
Key Specifications

| IO (at TC=120°C) | 2 A - Continuous average output current capability under thermally constrained heatsinking |
| VF (at IF=2A, TA=25°C) | 1.3 V - Low conduction loss enabling >85% efficiency in 5–20W wireless charging transmitters |
| tRR | 250 ns - Fast recovery minimizes switching losses and EMI in high-frequency bridge rectifiers |
| IFSM (8.3ms) | 60 A - Handles inrush surges during cold-start of offline SMPS without failure |
| IR (at VR=1000V, TA=25°C) | 1 μA - Negligible leakage preserves standby power budget in energy-efficient adapters |
| RθJL | 15 °C/W - Enables direct thermal coupling to PCB copper for passive cooling in space-constrained layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Higher VF (1.5V @ 2A), larger GBU package (10.5×7.0mm vs SOPA-4's 5.2×6.6mm), no UL recognition | Requires more PCB area and dissipates ~0.4W more at 2A; suitable only where space and safety certification are non-critical | Select when legacy GBU footprint compatibility is required and thermal headroom exceeds 5°C/W |
| MB2S (Vishay) | Lower IFSM (30A), higher IR (5μA @ 1000V), same SOPA-4 footprint but not UL-recognized | Limited surge robustness in high-inrush applications; unsuitable for wireless charging where 60A IFSM ensures reliability over 10,000 cycles | Choose only for cost-sensitive, non-safety-certified consumer accessories with <10W output |
Compared with GBU4K and MB2S, RABS20M uniquely combines UL recognition, miniature SOPA-4 size, 60A surge rating, and sub-μA leakage-making it optimal for space-constrained, safety-certified, and high-reliability wireless power and adapter designs.

FAQ
What is the maximum operating temperature for RABS20M?
The RABS20M has an operating junction temperature range of –55°C to +150°C, with continuous average output current rated at 2A when case temperature is held at +120°C. Thermal performance depends on PCB copper area and airflow; the 15°C/W junction-to-lead resistance assumes mounting on a 30mm × 30mm, 2oz copper pad per JEDEC JESD-51 standards.
Is RABS20M suitable for automotive applications?
RABS20M itself is not AEC-Q101 qualified, but Diodes Incorporated offers automotive-grade variants (e.g., RABS20M-AQ) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. For standard RABS20M, use in automotive infotainment or body electronics requires system-level qualification and derating per application-specific stress analysis.
How does RABS20M compare to standard KBP-type bridge rectifiers?
RABS20M replaces through-hole KBP2010 in SMT layouts with 70% smaller footprint and 40% lower profile. Unlike KBP devices, it features glass-passivated dies for improved humidity resistance, 250ns tRR (vs ~500ns for KBP), and UL recognition-enabling thinner, safer, and higher-frequency designs without sacrificing surge robustness.
Can RABS20M be used in synchronous rectification circuits?
No-RABS20M is a passive silicon bridge rectifier with fixed PN-junction conduction characteristics. It lacks gate control, MOSFET channels, or driver circuitry required for synchronous rectification. For active rectification, consider Diodes' AP22653 or similar integrated synchronous bridge controllers paired with external MOSFETs.
