Product details
Overview
RABF156-13 from Diodes Incorporated is a 600 V peak repetitive reverse voltage, 1.5 A average rectified output current, glass passivated surface-mount bridge rectifier in SOPA-4 (Type B) package. It delivers fast recovery time (250 ns), low forward voltage drop (1.3 V @ 1.5 A), and 5 μA max reverse leakage at 25°C, enabling high-efficiency AC–DC conversion in compact power supplies.
For engineers reviewing the RABF156-13 datasheet, RABF156-13 pinout, RABF156-13 application, or RABF156-13 equivalent, key selection criteria include rated blocking voltage, thermal resistance (RθJA = 80 °C/W), surge current capability (50 A IFSM), and RoHS-compliant lead-free plating for SMT manufacturing reliability.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass passivation for enhanced ruggedness and moisture resistance. Its SOPA-4 (Type B) package features a 3.8 mm pitch between outer terminals and a 4.2 mm × 6.4 mm body footprint optimized for automated placement and reflow soldering.
Designed for operation up to +150°C junction temperature, it exhibits stable reverse leakage (200 μA @ 125°C) and low total capacitance (17 pF per element @ 1 MHz, 4 V reverse bias), minimizing switching noise in high-frequency SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in AC line inputs up to 420 V RMS without breakdown. |
| IO (TC = +100°C) | 1.5 A - Continuous DC output current rating under thermal-limited board conditions. |
| VFM @ 1.5 A | 1.3 V - Low conduction loss per diode pair, reducing power dissipation in rectification stage. |
| tRR | 250 ns - Fast recovery minimizes reverse recovery charge and associated switching losses. |
| IR @ 25°C | 5 μA - Ultra-low leakage preserves efficiency in standby and light-load operation. |
| RθJA | 80 °C/W - Thermal resistance defines required PCB copper area for safe operation at full load. |
| IFSM (8.3 ms) | 50 A - Handles inrush surges from cold-start capacitive loads without failure. |
Pinout & Package
Package: SOPA-4 (Type B), surface-mount plastic case (UL 94V-0), 0.02 g weight, matte tin-plated terminals, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| LED Lighting Power Supply | USB-C Adapter Primary Rectification |
|---|---|
Use Scenario: AC input rectification in 12–24 W constant-current LED drivers operating from universal 90–264 VAC mains. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC line to pulsating DC prior to PFC and DC–DC stages. Use Value: 600 V VRRM ensures margin against 264 VAC line transients; 1.3 V VF limits conduction loss to <2 W at 1.5 A. |
Use Scenario: Input rectification in compact 30–65 W USB-C PD adapters with active clamp flyback or QR flyback topology. IC Role / Device Role / Timing Role: Primary-side AC–DC conversion before high-frequency transformer isolation. Use Value: SOPA-4 package enables tight layout near EMI filter; 250 ns tRR supports >65 kHz switching without excessive ringing. |
| Smart Home Appliance Power Module | Office Equipment Standby Supply |
Use Scenario: Mains-powered smart thermostats, plug-in sensors, and Wi-Fi-enabled appliances requiring reliable low-power auxiliary supply. IC Role / Device Role / Timing Role: Bridge rectifier feeding linear or buck-derived 5 V/3.3 V standby rail. Use Value: 5 μA IR at 25°C minimizes no-load consumption; UL 94V-0 molding ensures flame-retardant safety compliance. |
Use Scenario: Auxiliary power supply in printers, scanners, and multifunction devices where space and thermal management are constrained. IC Role / Device Role / Timing Role: Compact, surface-mount bridge replacing through-hole alternatives in multi-rail power architectures. Use Value: 80 °C/W RθJA allows thermal design with minimal copper; 50 A IFSM handles motor startup surges without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Higher VRRM (800 V), larger GBU-6 package (10.5 × 14.5 mm), slower tRR (500 ns). | Suitable for higher-voltage industrial supplies but requires 3× more PCB area. | Select when >600 V margin is needed and space is not constrained. |
| MB10F (Diodes Inc.) | Same VRRM (600 V), same IO (1.5 A), but DO-15 package (through-hole), no RoHS-3 compliance. | Requires wave soldering; incompatible with fully SMT production lines. | Choose only for legacy through-hole designs or prototyping with manual assembly. |
Compared with GBU6K and MB10F, RABF156-13 uniquely balances 600 V rating, SMT compatibility, fast recovery, and green compliance in a miniature SOPA-4 footprint-making it optimal for space-constrained, high-volume consumer power supplies.

FAQ
What is the maximum junction temperature for continuous operation?
The RABF156-13 has an operating junction temperature range of –55°C to +150°C. For continuous 1.5 A output current, thermal design must ensure junction temperature remains ≤150°C-typically achieved using ≥1.3 mm² copper pad per terminal on aluminum substrate PCB per datasheet Note 5.
Is RABF156-13 compatible with lead-free reflow profiles?
Yes. The device uses matte tin-plated terminals and is qualified for standard lead-free reflow per IPC/JEDEC J-STD-020, with peak temperature up to 260°C. Its moisture sensitivity level is Grade 1, eliminating bake requirements prior to assembly.
How does its 250 ns reverse recovery time impact EMI performance?
A 250 ns tRR reduces reverse recovery charge (Qrr), lowering high-frequency ringing during turn-off. This directly suppresses common-mode EMI in the 30–100 MHz band-critical for meeting CISPR-32 Class B emissions in compact adapters and LED drivers.
Can RABF156-13 replace RABF154-13 in existing designs?
Yes, with full functional and mechanical compatibility: both share identical SOPA-4 (Type B) package, pinout, thermal characteristics, and electrical specs except VRRM (400 V → 600 V). No layout or firmware changes are required-only verification that system overvoltage transients remain within new 600 V margin.
