Product details
Overview
RS3AB-13-F from Diodes Incorporated is a 100 V, 3.0 A surface-mount fast recovery rectifier in SMB package with 150 ns reverse recovery time, 1.3 V forward voltage at 3.0 A, and 100 A non-repetitive surge rating - used in AC/DC front-end rectification for offline switch-mode power supplies.
For engineers reviewing the RS3AB-13-F datasheet, RS3AB-13-F pinout, RS3AB-13-F application, or RS3AB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (100 V), average forward current (3.0 A @ TT = 75°C), fast recovery time (150 ns), thermal resistance (25 K/W), and SMB package compatibility with automated assembly.
Technical Context
This device is a single-phase, silicon planar epitaxial fast recovery rectifier with glass-passivated die construction. It delivers low forward voltage drop (1.3 V @ 3.0 A) and high surge capability (100 A, 8.3 ms half-sine) for high-efficiency power conversion stages.
Designed for operation under resistive or inductive loads at 60 Hz, it requires 20% current derating for capacitive loads. Reverse recovery is characterized at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A per JEDEC test conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ES3B-E3/57T (Vishay) | Same VRRM (100 V), IO (3.0 A), SMB package; trr = 150 ns, VF = 1.3 V - identical electrical specs | No functional difference; validated in same adapter and LED driver reference designs | Select based on lead-time and distributor stock availability |
| SB3100 (ON Semiconductor) | VRRM = 100 V, IO = 3.0 A, but trr = 250 ns and VF = 1.4 V - slower recovery and higher conduction loss | Acceptable where switching frequency ≤ 50 kHz; not recommended for high-density 100+ kHz SMPS | Use only if thermal margin exists and EMI constraints are relaxed |
Compared with ES3B-E3/57T, RS3AB-13-F offers identical performance and drop-in compatibility; versus SB3100, it delivers 100 ns faster recovery and 0.1 V lower VF - directly improving efficiency and thermal headroom in compact power supplies.

FAQ
What is the maximum allowable junction temperature for RS3AB-13-F?
The absolute maximum junction temperature is +150°C, with continuous operation limited to Tj ≤ 125°C under typical thermal design conditions. Derating begins at TT = 75°C per the forward current curve, and thermal design must account for RJT = 25 K/W using a 5.0 mm² copper pad as specified in the datasheet.
Can RS3AB-13-F replace a standard PN junction rectifier like 1N4007?
No - RS3AB-13-F is a fast recovery rectifier (trr = 150 ns), while 1N4007 is a general-purpose rectifier (trr > 2 µs). Substituting it in legacy 50/60 Hz linear supplies offers no benefit and risks overvoltage stress due to higher reverse recovery dv/dt; it is intended for SMPS, not line-frequency applications.
Is RS3AB-13-F compliant with RoHS and REACH regulations?
Yes - RS3AB-13-F is RoHS-compliant (lead-free termination, homogeneous material restrictions met) and REACH-conformant (SVHC substances below threshold). Full compliance documentation, including Certificate of Conformance, is available upon request from Diodes Incorporated's official portal.
Does RS3AB-13-F require heatsinking in typical applications?
Not for nominal 3.0 A operation at ambient ≤ 50°C with the specified 5.0 mm² copper pad - RJT = 25 K/W enables sufficient self-cooling. Heatsinking becomes necessary above 75°C ambient or when operating near IO limit continuously; thermal simulation using the provided junction-to-terminal resistance is recommended.
