Product details
Overview
RS2MA-13 from Diodes Incorporated is a 1000 V, 1.5 A surface-mount fast recovery rectifier in SMA package with 500 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge rating - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the RS2MA-13 datasheet, RS2MA-13 pinout, RS2MA-13 application, or RS2MA-13 equivalent, key selection criteria include peak reverse voltage (1000 V), fast recovery performance (500 ns), thermal resistance (20 K/W), and UL 94V-0 molded plastic case suitability for automated assembly and high-reliability power conversion.
Technical Context
This device is a glass-passivated, single-junction silicon PN junction fast recovery rectifier optimized for high-efficiency switching power supplies. It operates across –65 °C to +150 °C with cathode-band polarity marking and supports full-cycle rectification under resistive/inductive loads at 60 Hz.
Reverse recovery is characterized at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. Junction capacitance is 30 pF at 1 MHz and 4 V reverse bias, and thermal resistance is measured with 5.0 mm² copper pad heat sinking per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - blocks up to 1000 V repetitive reverse voltage, enabling use in 800 V DC bus systems with safety margin. |
| IO @ TT=120°C | 1.5 A - continuous average forward current rating at terminal temperature of 120 °C, defining steady-state power handling. |
| VFM @ IF=1.5A | 1.3 V - forward voltage drop at rated current, directly determining conduction loss and thermal load in rectifier stage. |
| trr | 500 ns - reverse recovery time, critical for minimizing switching losses and EMI in 50–100 kHz SMPS designs. |
| IFSM | 50 A - peak surge current capability for 8.3 ms half-sine, supporting inrush and transient overload tolerance. |
| RJT | 20 K/W - junction-to-terminal thermal resistance with specified PCB copper pad, enabling accurate thermal design for board-level cooling. |

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 VRRM, 1.0 A IO, 75 ns trr, TO-277 package | Limited to ≤600 V systems; faster recovery but lower current/voltage rating | Select when higher speed is prioritized over voltage headroom in <600 V designs. |
| ON Semi MUR160 | 600 V VRRM, 1.0 A IO, 75 ns trr, DO-41 package | Through-hole mounting; lower surge rating (30 A) and higher thermal resistance | Choose only for legacy through-hole boards where SMA footprint is not feasible. |
Compared with RS2MA-13, STTH1L06S offers superior speed but sacrifices 400 V blocking and 0.5 A current capacity; MUR160 trades surface-mount compatibility and thermal performance for legacy assembly - RS2MA-13 remains optimal for new 1000 V, SMT-based power designs requiring robust surge and thermal behavior.

FAQ
What is the maximum operating temperature for RS2MA-13?
The RS2MA-13 has an operating junction temperature range of –65 °C to +150 °C. Its terminal temperature must be limited to 120 °C to sustain the rated 1.5 A average forward current. Derating curves in the datasheet specify linear reduction above that point, down to zero current at 150 °C terminal temperature.
Is RS2MA-13 suitable for capacitive-load rectification?
No - the datasheet explicitly requires 20% current derating for capacitive loads due to higher peak currents and stress on the die. For such applications, consider soft-recovery or ultrafast alternatives with lower trr and higher IFSM, or add series inrush limiting.
Does RS2MA-13 have a defined cathode marking?
Yes - the RS2MA-13 uses a cathode band marking on the SMA package body, consistent with industry-standard polarity identification. This band aligns with the cathode terminal and is visible under standard optical inspection during automated placement and post-solder verification.
Can RS2MA-13 replace RS2M in existing designs?
Yes - RS2MA-13 is the tape-and-reel packaging variant of RS2M (same electrical specs, SMA package, and marking). The "-13" suffix denotes 13-inch reel packaging per EIA-481; no circuit or layout changes are required for substitution in production.
