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, designed for low-voltage full-bridge AC-to-DC conversion in compact wireless charging receiver modules.
For engineers reviewing the RABS20M datasheet, RABS20M pinout, RABS20M application, or RABS20M equivalent, key selection criteria include its SOPA-4 package footprint, 250ns reverse recovery time, 60A non-repetitive surge rating, thermal resistance of 15°C/W (junction-to-lead), and UL recognition under file #E364304.
Technical Context
This single-phase full-wave bridge rectifier integrates four fast recovery diodes in a monolithic SOPA-4 package, optimized for high-frequency switching environments where low reverse recovery charge and minimal EMI generation are critical. Its glass-passivated die construction ensures stable performance across -55°C to +150°C operating range.
The device delivers 2A average output current at TC = +120°C with derating to ~1.6A for capacitive loads, supported by 14.9 A²s I²t fusing rating and 27pF junction capacitance per element at 4V/1MHz - enabling clean rectification in space-constrained, thermally demanding applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltages up to 1000V without breakdown in AC line or flyback snubber circuits. |
| IO (TC = +120°C) | 2.0 A - Sustains continuous DC output current when case temperature is held at 120°C, typical for enclosed power adapters. |
| VF @ 2A, 25°C | 1.3 V - Forward drop per diode leg determines conduction loss; total bridge drop is ~2.6V at full load. |
| tRR | 250 ns - Fast recovery minimizes switching losses and EMI during high-frequency rectification (e.g., >100kHz wireless charging). |
| IR @ 1000V, 25°C | 1 μA - Negligible leakage preserves efficiency in standby and light-load conditions. |
| IFS M | 60 A - Handles short-duration surges (8.3ms half-sine) common during cold-start or input transients. |
| RθJL | 15 °C/W - Enables thermal design with standard PCB copper pads; junction-to-lead path dominates heat dissipation. |
Pinout & Package
Package: SOPA-4 (Type WX), surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1, UL 94V-0 rated molding compound, weight ≈ 0.88 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode 1) | AC Input Terminal | One AC input node of the bridge; connects to transformer secondary or resonant tank output. |
| 2 (Cathode) | DC Positive Output | Common cathode node delivering rectified positive DC voltage to filter capacitor or regulator. |
| 3 (Anode 2) | AC Input Terminal | Second AC input node; completes full-wave bridge configuration with Pin 1. |
| 4 (Anode/Cathode Common) | DC Negative Output / Bridge Center Tap | Common anode node serving as DC ground return path; electrically tied to system GND. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Ensures long-term reliability and stable electrical parameters under thermal cycling and humidity exposure. |
| EMI-optimized rectification | Low stored charge and 250ns tRR reduce high-frequency ringing and conducted emissions in wireless power receivers. |
| SOPA-4 miniature footprint | 5.05 × 6.6 mm body size saves >40% board area vs. traditional SOIC-14 bridge packages. |
| UL Recognized (E364304) | Validates safety compliance for end-equipment certification in consumer and industrial power supplies. |
| Lead-free & halogen-free | Meets RoHS 3 and JEDEC J-STD-020 Level 1 requirements without compromising solderability or thermal performance. |
Applications
| Wireless Charging Receiver | USB-C PD Adapter Secondary Side |
|---|---|
Use Scenario: Full-wave rectification of 100–200kHz AC output from Qi-compliant transmitter coils into DC for battery charging ICs. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion stage; operates synchronously with resonant frequency and handles burst-mode transitions. Use Value: 250ns tRR and 27pF CT minimize switching noise coupling into sensitive communication bands (e.g., NFC, BLE coexistence). |
Use Scenario: Rectifying high-frequency AC from LLC or flyback secondary windings in compact 30–65W USB-C PD adapters. IC Role / Device Role / Timing Role: Fixed-function bridge rectifier replacing discrete diode solutions; enables <5mm profile designs. Use Value: SOPA-4 footprint and 15°C/W RθJL allow direct thermal coupling to PCB ground plane, eliminating need for heatsinks. |
| Industrial IoT Power Supply | Smart Home AC/DC Module |
Use Scenario: Converting 50/60Hz mains-derived AC (via small isolation transformer) into regulated DC for microcontrollers and sensors in sealed enclosures. IC Role / Device Role / Timing Role: Isolated AC input conditioning block; operates continuously at ambient temperatures up to +85°C. Use Value: 1μA IR at 25°C and <200μA at 125°C ensures minimal standby power loss over full industrial temperature range. |
Use Scenario: Low-profile bridge rectification in wall-mounted smart switches, LED drivers, and voice assistant power stages. IC Role / Device Role / Timing Role: Space-constrained front-end rectifier supporting dual-output (5V + 3.3V) regulation. Use Value: UL recognition and RoHS 3 compliance enable global regulatory approval without redesign or additional testing. |
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 (1.1V typ @ 4A), larger GBU-4 package (10.5 × 14.2 mm), 50A IFSM, no UL recognition. | Requires more PCB area; suitable for higher-current, lower-frequency (<60kHz) applications where thermal mass compensates for slower recovery. | Select if cost-per-amp is prioritized over size and EMI performance. |
| MB2S (Vishay) | Smaller SMB package (4.6 × 5.8 mm), 0.8A IO rating, 600V VRRM, 150ns tRR, no UL file. | Limited to sub-1W auxiliary supplies; insufficient for 2A wireless charging loads or 1000V line isolation. | Only viable for low-power signal-level rectification where voltage and current ratings align. |
Compared with GBU4K and MB2S, RABS20M uniquely balances 1000V blocking, 2A current, 250ns speed, SOPA-4 miniaturization, and UL safety certification - making it the only drop-in solution for thermally dense, EMI-sensitive, globally certified 2A bridge applications.

FAQ
What is the maximum allowable case temperature for continuous operation?
RABS20M is rated for 2.0A average output current at TC = +120°C. Operation above this temperature requires linear derating per Figure 1 in DS43750; at TC = +140°C, IO drops to approximately 1.3A. Exceeding the 150°C maximum storage temperature risks permanent parametric shift or bond wire failure.
Can RABS20M be used in automotive applications?
RABS20M is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949 manufacturing evidence in its public datasheet. While its -55°C to +150°C operating range meets automotive ambient requirements, Diodes explicitly states that automotive-grade variants require direct consultation and custom qualification - standard RABS20M is intended for commercial/industrial use only.
How does the SOPA-4 package compare thermally to traditional SOIC-14 bridges?
SOPA-4 offers significantly lower thermal resistance (RθJL = 15°C/W) than SOIC-14 bridges (~35–45°C/W), due to direct lead-frame conduction paths and optimized internal die attach. However, its smaller pad area limits absolute heat dissipation; optimal PCB layout uses ≥30mm² 2oz copper on both sides connected via multiple vias to maximize cooling.
Is the 1000V VRRM rating suitable for 230VAC mains input?
Yes - 230VAC RMS yields ~325V peak, and with safety margin (IEC 62368-1 requires ≥2× working voltage), 1000V VRRM provides robust derating. The device has been validated in 230VAC-input offline SMPS designs, including those with 1.5kV surge immunity, provided proper PCB creepage/clearance and external MOV clamping are implemented.
