Product details
Overview
S5M R7G from Taiwan Semiconductor is a 5A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 100A peak surge current capability, 1.15V max forward voltage at 5A, and 10µA max reverse leakage at 25°C - deployed in high-voltage AC/DC front-end stages of industrial SMPS.
For engineers reviewing the S5M R7G datasheet, S5M R7G pinout, S5M R7G application, or S5M R7G equivalent, key selection criteria include verified VRRM = 1000V, IFSM = 100A, TJ(max) = 150°C, RθJL = 13°C/W thermal resistance, and DO-214AB mechanical compatibility with automated SMT placement.
Technical Context
This single-die standard recovery rectifier operates with a typical reverse recovery time (trr) of 1500 ns under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions and exhibits 60 pF junction capacitance at 1 MHz and 4.0V reverse bias - suitable for non-synchronous flyback and forward converter outputs where moderate switching speed and high voltage blocking are prioritized over ultrafast recovery.
Its glass-passivated chip junction ensures stable performance across -55°C to +150°C junction temperature range, while matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements - supporting reliable reflow assembly in high-volume power supply manufacturing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - blocks up to 1000V repetitive reverse voltage, enabling use in 800V DC bus or 600VAC input rectification |
| IF | 5 A continuous - supports sustained output current in medium-power offline converters |
| IFSM | 100 A (8.3ms half-sine) - withstands inrush surges during cold-start or line transients |
| VF (max) | 1.15 V @ 5A, 25°C - limits conduction loss to ≤5.75W at full load, easing thermal design |
| IR (max) | 10 µA @ 25°C, 1000V - ensures low standby leakage in high-impedance hold-up circuits |
| RθJL | 13 °C/W - enables direct lead-to-heatsink thermal path for PCB copper pour cooling |
| trr | 1500 ns - compatible with <100 kHz switching topologies; not suited for >300 kHz ZVS/ZCS designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06FW | 600V VRRM, 5A IF, 50 ns trr, TO-277 package | Ultrafast recovery; lower voltage rating; higher cost per unit | Prefer when operating >200 kHz or requiring <100 ns trr; not drop-in due to different package and pinout |
| ON Semi MUR560 | 600V VRRM, 5A IF, 75 ns trr, DO-201AD package | Faster recovery but lower voltage rating and larger footprint than DO-214AB | Select for legacy through-hole designs or where faster trr justifies trade-off in voltage margin and board space |
Compared with STTH5L06FW and MUR560, the S5M R7G delivers superior 1000V blocking and DO-214AB SMT compatibility at lower cost - making it optimal for cost-sensitive, high-voltage, medium-frequency industrial power supplies where 1500 ns trr is acceptable.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rated for the S5M R7G?
The S5M R7G is rated for 1000 V repetitive peak reverse voltage (VRRM), confirmed in the absolute maximum ratings table of Taiwan Semiconductor's F2102 datasheet. This rating allows the S5M R7G to safely block 1000V reverse polarity transients in high-voltage DC bus applications, such as industrial SMPS front-ends and universal-input LED drivers. It is the highest voltage grade in the S5A–S5M family.
Does the S5M R7G have a specified reverse recovery time (trr), and what test conditions apply?
Yes, the S5M R7G has a typical reverse recovery time (trr) of 1500 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions per the electrical specifications table. This value reflects its standard recovery behavior and confirms suitability for switching frequencies up to ~100 kHz. The S5M R7G is not classified as an ultrafast or soft-recovery diode.
Is the S5M R7G compliant with RoHS and halogen-free standards?
Yes, the S5M R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the features section of the official Taiwan Semiconductor documentation. Its matte tin-plated leads and UL 94V-0 molding compound further support environmentally regulated manufacturing and end-product certifications.
What is the thermal resistance from junction to lead (RθJL) for the S5M R7G, and how does it impact PCB layout?
The S5M R7G has a junction-to-lead thermal resistance (RθJL) of 13°C/W, enabling efficient heat transfer from the die directly into the PCB copper via the leads. This allows designers to use internal or external copper pours connected to both terminals as passive heatsinking - reducing or eliminating the need for additional thermal vias or metal-core substrates in medium-power applications.
What marking code identifies the S5M R7G on the device body?
The S5M R7G is marked with "S5M" on the device body, consistent with Taiwan Semiconductor's ordering code convention where "x" in S5x denotes voltage grade (S5M = 1000V). The "R7G" suffix indicates reel packaging and green compound variant per internal TSC coding - visible only on tape-and-reel packaging labels, not on the diode itself.
