Product details
Overview
S3DHR7G from Taiwan Semiconductor is a 200 V, 3 A surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 100 A surge current capability, 1.15 V max forward voltage at 3 A, and 10 µA max reverse leakage at 25°C - used in AC/DC front-end rectification for compact switch-mode power supplies.
For engineers reviewing the S3DHR7G datasheet, S3DHR7G pinout, S3DHR7G application, or S3DHR7G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (13 °C/W junction-to-lead), reverse recovery time (1500 ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150°C and supports continuous forward current up to 3 A at case temperature ≤75°C. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect design trade-offs favoring cost-effective general-purpose rectification over ultrafast switching.
The device uses glass-passivated chip junctions and matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AB molded body, and the package meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage the diode blocks without breakdown in normal operation |
| IF | 3 A - continuous average forward current rating at TA = 25°C with adequate heatsinking |
| IFSM | 100 A - non-repetitive peak surge current (8.3 ms half-sine) the device withstands during line transients |
| VF (max) | 1.15 V @ 3 A, 25°C - forward voltage drop determining conduction loss and thermal load in rectifier stage |
| IR (max) | 10 µA @ 200 V, 25°C - reverse leakage current affecting standby power and high-impedance circuit integrity |
| trr | 1500 ns - reverse recovery time influencing switching losses and EMI in higher-frequency SMPS designs |
| RθJL | 13 °C/W - thermal resistance from junction to lead, critical for estimating die temperature rise under PCB copper pad cooling |
Pinout & Package

Applications
| AC/DC Adapter Rectification | LED Driver Input Stage |
|---|---|
Use Scenario: Converts 50/60 Hz AC mains to pulsating DC in wall-wart adapters rated ≤36 W. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier providing bulk DC input to PWM controller and secondary-side regulation. Use Value: Low VF (≤1.15 V) minimizes conduction loss at 3 A, improving adapter efficiency and reducing heatsink requirements. | Use Scenario: Rectifies AC input in isolated LED drivers for commercial downlights and street lighting fixtures. IC Role / Device Role / Timing Role: Front-end bridge or single-diode rectifier feeding bulk capacitor and PFC stage or flyback controller. Use Value: 100 A IFSM withstands inrush surges from cold-start capacitors, extending driver field life. |
| Industrial SMPS Input Stage | DC-DC Converter Input Protection |
Use Scenario: Used in 24–48 V input industrial power modules where space-constrained DO-214AB footprint is required. IC Role / Device Role / Timing Role: Input rectifier in offline or wide-input-range isolated DC-DC converters operating up to 150°C ambient. Use Value: 150°C TJ(max) and 13 °C/W RθJL enable reliable operation with minimal PCB copper, reducing BOM count. | Use Scenario: Reverse-polarity protection and input rectification in 12 V/24 V automotive-grade DC-DC modules. IC Role / Device Role / Timing Role: Standalone protection diode placed before buck controller IC to block reverse battery connection or backfeed. Use Value: 200 V VRRM provides margin against load-dump transients (ISO 7637-2 Pulse 5a), enhancing system robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | 200 V, 3 A, TO-220AC package; VF = 1.15 V @ 3 A but RθJA = 50 °C/W vs. S3DHR7G's 47 °C/W | Requires through-hole mounting and heatsink; unsuitable for fully SMT designs | Select STTH3L02 only when higher thermal mass or legacy through-hole assembly is mandated |
| ON Semi MUR320 | 200 V, 3 A, DO-214AB; ultrafast trr = 75 ns (vs. 1500 ns); VF = 1.3 V @ 3 A | Better for >100 kHz SMPS; higher VF increases conduction loss in 50–100 kHz adapters | Choose MUR320 when EMI reduction and faster switching outweigh conduction loss penalties |
Compared with STTH3L02 and MUR320, the S3DHR7G offers optimal balance of low VF, SMT compatibility, and cost for ≤100 kHz general-purpose rectification - making it preferred for space-constrained, thermally moderate adapter and lighting applications where ultrafast recovery is unnecessary.

FAQ
What is the maximum junction temperature rating for the S3DHR7G?
The S3DHR7G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows operation in high-ambient environments such as enclosed LED drivers or industrial power modules. Derating curves confirm usable forward current down to 0 A at 150°C case temperature. Thermal design must respect RθJL = 13 °C/W to avoid exceeding this limit under 3 A load.
Does the S3DHR7G meet RoHS and halogen-free requirements?
Yes, the S3DHR7G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor S3A–S3M datasheet (Version O2301). This compliance applies to all materials including molding compound, lead finish, and internal die attach - satisfying EU Directive 2011/65/EU and JEDEC JS709C requirements for environmentally restricted substances.
What is the reverse recovery time (trr) specification for the S3DHR7G?
The S3DHR7G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions per the Electrical Specifications table. This value classifies it as a standard recovery rectifier - appropriate for 50/60 Hz and ≤100 kHz switching applications but not recommended for high-frequency resonant topologies where trr < 100 ns is required.
Is the S3DHR7G suitable for use in automotive applications?
The S3DHR7G is not qualified to AEC-Q101 and is not recommended for automotive safety-critical systems. However, it may be used in non-safety automotive auxiliary circuits (e.g., interior lighting, infotainment power supplies) where ambient temperatures remain ≤125°C and transients comply with ISO 7637-2 Pulse 1/2. For engine bay or ADAS applications, AEC-Q101-qualified alternatives must be selected instead of the S3DHR7G.
What packaging and reel quantity is offered for the S3DHR7G?
The S3DHR7G is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, consistent with the Ordering Information table in the Taiwan Semiconductor S3A–S3M datasheet. Reel diameter, orientation, and leader/trailer lengths conform to EIA-481-D standards. No alternate packaging (e.g., ammo pack or tube) is specified for this part number.
