Product details
Overview
S2M R5G from Taiwan Semiconductor is a 2 A, 1000 V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, 50 A surge capability, and 1.15 V max forward voltage at 2 A - used in AC/DC front-end stages of industrial SMPS and LED drivers.
For engineers reviewing the S2M R5G datasheet, S2M R5G pinout, S2M R5G application, or S2M R5G equivalent, key selection factors include repetitive peak reverse voltage (1000 V), thermal resistance (16 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMB-compatible automated placement suitability.
Technical Context
The S2M R5G operates as a single-die, unidirectional standard recovery rectifier with no integrated snubber or fast-recovery optimization. Its 1500 ns reverse recovery time and 30 pF junction capacitance reflect conventional PN-junction behavior suited for line-frequency and low-to-moderate switching frequency applications up to ~100 kHz.
Thermal design relies on its 16 °C/W junction-to-lead resistance and 53 °C/W junction-to-ambient rating, requiring adequate PCB copper area for heatsinking. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports DC bus voltages up to 707 V RMS input in bridge configurations |
| IF | 2 A continuous - rated for steady-state conduction in 24–48 V output SMPS secondary-side rectification |
| IFSM | 50 A (8.3 ms half-sine) - withstands inrush surges during cold-start of offline converters |
| VF | ≤1.15 V @ 2 A, 25°C - contributes ≤2.3 W conduction loss per device at full load |
| trr | 1500 ns - limits usable switching frequency; not suitable for >100 kHz synchronous rectifier replacement |
| RθJL | 16 °C/W - enables direct thermal coupling to PCB copper pour for passive cooling |
| IR | ≤1 µA @ 25°C, ≤125 µA @ 125°C - ensures low leakage in high-impedance hold-up circuits |

Applications
| Industrial SMPS Front-End | LED Driver Secondary Rectification |
|---|---|
Use Scenario: AC/DC conversion stage in 100–300 W open-frame power supplies for factory automation controllers. IC Role / Device Role / Timing Role: Standard recovery rectifier in voltage-doubler or full-wave bridge configuration. Use Value: 1000 V VRRM safely handles 265 VAC mains transients; 50 A IFSM absorbs startup surges without derating. | Use Scenario: Output rectification in constant-current LED drivers for street lighting fixtures. IC Role / Device Role / Timing Role: Unidirectional current path delivering filtered DC to LED string. Use Value: Low VF (≤1.15 V) minimizes conduction loss at 2 A nominal current, improving driver efficiency by ~0.8% vs. higher-VF alternatives. |
| AC Adapter Output Stage | DC-DC Converter Input Protection |
Use Scenario: Secondary-side rectification in universal-input 12 V/2 A wall adapters for networking equipment. IC Role / Device Role / Timing Role: Discrete rectifier replacing integrated Schottky solutions where cost and thermal margin are prioritized. Use Value: DO-214AA footprint allows drop-in replacement on legacy layouts; 150°C TJ rating supports compact enclosure designs. | Use Scenario: Reverse-polarity and backfeed protection at input of isolated DC-DC modules in telecom shelf systems. IC Role / Device Role / Timing Role: Blocking diode preventing damage from external supply faults or hot-swap events. Use Value: 1000 V VRRM provides margin against induced transients on 48 V distribution rails; 1 µA IR ensures negligible standby drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600 V VRRM, 2 A IF, 1.15 V VF, TO-220AC package | Higher thermal mass but requires through-hole mounting and heatsink | Preferred where board space permits and higher surge margin is needed beyond SMB footprint limits |
| ON Semi MUR220 | 200 V VRRM, 2 A IF, 1.15 V VF, DO-214AA, fast recovery (trr = 35 ns) | Lower voltage rating but significantly faster switching for higher-frequency topologies | Select when operating above 50 kHz or needing reduced EMI; not interchangeable for 1000 V applications |
Compared with STTH2R06 and MUR220, the S2M R5G uniquely balances 1000 V blocking capability, SMB surface-mount compatibility, and cost-effective standard recovery performance - making it optimal for fixed-frequency, medium-power industrial rectification where fast recovery is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S2M R5G?
The S2M R5G has a VRRM rating of 1000 V, verified per Taiwan Semiconductor's N2102 datasheet revision. This value defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown. It enables use in 230 VAC-derived DC buses with sufficient safety margin and is confirmed in the Absolute Maximum Ratings table alongside other S2x variants.
Is the S2M R5G RoHS and halogen-free compliant?
Yes, the S2M R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official datasheet. The molding compound meets UL 94V-0, and terminals are matte tin-plated - all verified in the Mechanical Data and Compliance notes of Taiwan Semiconductor's S2A–S2V documentation.
What is the reverse recovery time (trr) of the S2M R5G, and how does it affect circuit design?
The S2M R5G has a trr of 1500 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This standard recovery characteristic limits its use to line-frequency or low-switching-frequency applications (<100 kHz); using it in high-frequency converters increases switching losses and EMI. The value is measured and published in the Electrical Specifications table.
Does the S2M R5G have a defined moisture sensitivity level (MSL)?
Yes, the S2M R5G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow. This is confirmed in the FEATURES list and supports standard automated SMT assembly without special handling protocols.
What package type and marking code does the S2M R5G use?
The S2M R5G uses the DO-214AA (SMB) surface-mount package, with cathode polarity indicated by a molded band. Its marking code is "S2M", as shown in the Absolute Maximum Ratings table and Ordering Information section - distinguishing it within the S2x family by its 1000 V VRRM rating.
