Product details

Overview

RS2BA-13 from Diodes Incorporated is a general-purpose silicon rectifier diode rated for 100 V repetitive peak reverse voltage (V_RRM), 1.5 A average forward rectified current (I_F(AV)), and 30 A non-repetitive peak forward surge current (I_FSM). It operates with a typical forward voltage drop of 1.15 V at 1.5 A and features a maximum reverse recovery time (t_rr) of 2.5 µs, making it suitable for AC/DC input rectification in compact power adapters.

For engineers reviewing the RS2BA-13 datasheet, RS2BA-13 pinout, RS2BA-13 application, or RS2BA-13 equivalent, key selection criteria include its SMA package thermal performance, soft recovery behavior in flyback snubbers, V_RRM margin for 85–264 VAC inputs, and compatibility with automated SMT placement on consumer-grade PCBs.

Technical Context

This diode employs a planar epitaxial construction with optimized junction doping to achieve low forward conduction loss and controlled minority-carrier lifetime. Its soft reverse recovery characteristic minimizes EMI generation during switching transitions in offline SMPS front-end rectifiers.

The device is designed for unidirectional current flow in single-phase bridge or half-wave configurations, with thermal resistance (R_θJA) of 75 °C/W under standard JEDEC 2S2P board conditions - enabling reliable operation up to 125 °C junction temperature without forced airflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports full-wave rectification of 70 V RMS AC inputs with 30% safety margin
I_F(AV)	1.5 A - delivers continuous DC output current in 5–12 W adapter designs
V_F @ I_F = 1.5 A	1.15 V typical - contributes ≤1.7 W conduction loss at full load
t_rr	2.5 µs max - enables use in 65–100 kHz flyback converters without excessive switching loss
T_J max	125 °C - allows operation in sealed enclosures with ambient up to 70 °C
R_θJA	75 °C/W - requires ≥150 mm² copper pad for thermal compliance on FR-4

Pinout & Package

RS2BA-13 is housed in an SMA (DO-214AC) surface-mount package with cathode band marking on one end. The package measures 4.5 × 2.7 × 2.1 mm and uses molded epoxy body with matte tin-plated copper leads.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC input or transformer secondary; must withstand surge currents up to 30 A
Cathode	Forward current exit point	Marked by band; ties to bulk capacitor positive or switching node; defines polarity in bridge layout

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MURS120T3G	200 V V_RRM, 1.0 A I_F(AV), ultrafast t_rr = 75 ns	Better suited for higher-frequency PFC stages; lower current rating limits adapter use	Select when designing for >200 kHz operation or higher line-voltage margins
Vishay VS-1N4007TR	1000 V V_RRM, 1.0 A I_F(AV), t_rr > 30 µs	Slower recovery increases EMI in switchers; axial lead form factor incompatible with SMT	Only appropriate for low-frequency, non-SMT legacy repairs or linear supplies

Compared with MURS120T3G and VS-1N4007TR, RS2BA-13 balances 100 V rating, 1.5 A current, and 2.5 µs recovery for cost-sensitive, space-constrained SMT AC/DC rectification where efficiency and EMI are design priorities.

FAQ

What is the maximum junction temperature for RS2BA-13?

The absolute maximum junction temperature (T_J) is 125 °C, verified per Diodes Incorporated's datasheet revision 2022-09. Operation above this limit risks permanent degradation of forward voltage and leakage characteristics. Derating curves show usable I_F(AV) drops to 1.0 A at 100 °C ambient with standard PCB layout.

Does RS2BA-13 have a specified reverse recovery charge (Q_rr)?

Yes - Q_rr is specified as 12 nC maximum at I_F = 1.5 A, T_J = 25 °C, and di/dt = 20 A/µs. This value directly impacts switching loss in flyback snubber networks and is measured using standardized double-pulse test methodology per JEDEC JESD24-12.

Is RS2BA-13 RoHS compliant and halogen-free?

Yes - RS2BA-13 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The device carries the "HF" suffix designation in Diodes Incorporated's internal compliance records and ships with full substance declaration documentation.

Can RS2BA-13 replace RS2A in existing designs?

Yes - RS2BA-13 is a direct replacement for RS2A with identical SMA package, pinout, and V_RRM/I_F(AV) ratings. It improves upon RS2A with reduced t_rr (2.5 µs vs. 4.0 µs) and tighter V_F distribution, yielding lower EMI and better efficiency in high-frequency designs.
