Product details
Overview
S5A R7G from Taiwan Semiconductor is a 5 A, 50 V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15 V max forward voltage at 5 A, 100 A peak surge current capability, and 150 °C maximum junction temperature-used in AC/DC front-end rectification for compact switching mode power supplies.
For engineers reviewing the S5A R7G datasheet, S5A R7G pinout, S5A R7G application, or S5A R7G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (13 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and tape-and-reel packaging for automated assembly.
Technical Context
The S5A R7G is a single-die, standard recovery rectifier with glass-passivated junction, optimized for high-current, medium-voltage DC output stages in offline SMPS. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs favoring low conduction loss over ultra-fast switching.
Thermally, it delivers 13 °C/W junction-to-lead resistance and 47 °C/W junction-to-ambient resistance under natural convection, supporting continuous 5 A operation up to 110 °C ambient when mounted on ≥1 in² copper area-validated per JEDEC JESD201 Class 2 whisker testing and UL 94V-0 molding compound.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR550G | Ultrafast recovery (75 ns), higher VF (1.7 V @ 5 A), same DO-214AB package | Better suited for >200 kHz PFC stages; higher conduction loss limits use in thermally constrained adapters | Select when trr < 100 ns is required and thermal headroom exists |
| Vishay VS-5EWH05FN-M3/45 | Same 50 V VRRM, 5 A IF, but TO-277 package (lower RθJA = 35 °C/W), no tape-and-reel option | Preferred for high-power density industrial supplies needing superior thermal dissipation; incompatible with standard SMC pick-and-place feeders | Select when board-level thermal resistance is critical and manual or tray-based assembly is acceptable |
Compared with MUR550G and VS-5EWH05FN-M3/45, the S5A R7G prioritizes cost-effective, high-volume manufacturability in space-limited AC/DC adapters-offering optimal balance of surge robustness, moisture resilience, and automated assembly readiness at 50 V rating.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S5A R7G?
The S5A R7G has a VRRM of 50 V, meaning it can block up to 50 V of reverse voltage continuously without breakdown. This rating aligns with its marking code "S5A" and is validated per JEDEC test conditions. The S5A R7G is intended for use in circuits where peak reverse voltage does not exceed this value-such as 35 V RMS inputs in adapter applications. Exceeding 50 V risks avalanche failure and permanent damage to the S5A R7G.
Does the S5A R7G support automated SMT assembly?
Yes, the S5A R7G is explicitly designed for automated placement, with DO-214AB (SMC) package geometry, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020-eliminating bake requirements. Its standardized footprint and 0.210 g weight ensure reliable pickup and placement at speeds exceeding 25,000 components per hour. The S5A R7G is supplied in 3,000-unit tape-and-reel format compatible with industry-standard feeders.
What is the forward voltage drop of the S5A R7G at rated current?
The S5A R7G exhibits a maximum forward voltage (VF) of 1.15 V at 5 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but system-level losses remain dominated by this 1.15 V ceiling. This VF directly determines conduction loss (≤5.75 W at full load), making thermal design critical for sustained S5A R7G operation.
Is the S5A R7G RoHS and halogen-free compliant?
Yes, the S5A R7G meets EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. Its molding compound contains no brominated or chlorinated flame retardants, and lead content is below 1000 ppm. Compliance is verified through material declarations and third-party testing. This makes the S5A R7G suitable for export to EU, China, and other regulated markets-no exemptions or deviations apply to the S5A R7G.
What is the junction-to-lead thermal resistance (RθJL) of the S5A R7G?
The S5A R7G has a typical junction-to-lead thermal resistance (RθJL) of 13 °C/W, measured per JEDEC JESD51-14. This parameter quantifies how efficiently heat transfers from the silicon die to the soldered lead interface-critical for predicting temperature rise under load. With proper PCB copper pour and minimal thermal interface resistance, the S5A R7G maintains safe junction temperatures even at 5 A continuous current. This RθJL value is confirmed in TSC's F2102 datasheet revision for the S5A R7G.
