Product details

Overview

RS2MA-13-F from Diodes Incorporated is a 1000 V, 1.5 A surface-mount fast recovery rectifier in SMA package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge rating - deployed in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the RS2MA-13-F datasheet, RS2MA-13-F pinout, RS2MA-13-F application, or RS2MA-13-F equivalent, key selection criteria include peak repetitive reverse voltage (1000 V), thermal resistance (20 °C/W), fast recovery performance (150 ns), RoHS-compliant lead-free plating, and AEC-Q200 suitability for automotive-grade designs.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for high-efficiency switching power conversion. Its glass-passivated die construction ensures stable reverse leakage (<5 µA @ 25°C) and robust surge tolerance (50 A, 8.3 ms half-sine).

The fast recovery characteristic (trr = 150 ns) enables reduced switching losses in 20–100 kHz SMPS topologies. Thermal design is supported by low R_θJT (20 °C/W) when mounted on 5.0 mm² copper pads, enabling reliable operation up to +150°C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands peak reverse transients in universal-input offline converters without breakdown.
I_O	1.5 A @ T_T = 120°C - Continuous DC output current capability under standard heatsinking conditions.
V_F	1.3 V @ I_F = 1.5 A - Low conduction loss improves efficiency in high-current rectifier legs.
t_rr	150 ns - Enables use in medium-frequency flyback and forward converters with minimal switching loss.
I_FSM	50 A (8.3 ms) - Survives inrush and line surge events common in AC mains input stages.
R_θJT	20 °C/W - Junction-to-terminal thermal resistance supports predictable thermal modeling on PCB copper pads.
C_T	30 pF @ 1 MHz, 4 V - Low junction capacitance minimizes capacitive coupling noise in EMI-sensitive applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	600 V V_RRM, 1.0 A I_O, trr = 75 ns, SMA package	Limited to lower-voltage inputs (≤265 V_AC); faster recovery but lower surge rating (30 A)	Select when higher speed and lower V_F (1.1 V) are prioritized over voltage headroom and surge robustness.
ON Semi MUR160	600 V V_RRM, 1.0 A I_O, trr = 75 ns, DO-41 through-hole	Through-hole mounting; not surface-mount compatible; lacks RoHS 3 compliance and AEC-Q200 alignment	Choose only for legacy through-hole designs where rework flexibility outweighs automated assembly and environmental compliance needs.

Compared with STTH1L06S and MUR160, RS2MA-13-F delivers superior voltage margin (1000 V), higher continuous current (1.5 A), and automotive-ready qualification - making it optimal for new industrial and automotive designs demanding reliability and regulatory alignment.

FAQ

What is the maximum junction temperature for RS2MA-13-F?

The absolute maximum junction temperature is +150°C, with derated average output current beginning at terminal temperatures above 120°C. The device maintains specified electrical characteristics across its full –65°C to +150°C operating range, validated per JESD22-A108.

Is RS2MA-13-F suitable for automotive applications?

Yes - RS2MA-13-F is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101, Diodes offers AEC-Q200-compliant variants in the same family and can support automotive change control upon request.

How does the SMA package affect thermal performance?

The SMA package achieves R_θJT = 20 °C/W when soldered to 5.0 mm² copper pads per JEDEC standards. Its low mass (0.065 g) and direct thermal path to PCB copper enable rapid heat dissipation, supporting sustained 1.5 A operation at elevated ambient temperatures.

What is the reverse recovery test condition for trr = 150 ns?

The 150 ns reverse recovery time is measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, per Figure 5 in DS15004 Rev. 12–2. This reflects real-world switching behavior in typical flyback and forward converter gate drive circuits.
