Product details
Overview
S5D-E3/9AT from Vishay General Semiconductor is a surface-mount glass passivated rectifier diode rated for 5.0 A average forward current, 200 V maximum repetitive peak reverse voltage, and 100 A non-repetitive surge current; it features 1.15 V forward voltage drop at 5.0 A and operates up to 175 °C junction temperature in power supply rectification and freewheeling applications.
For engineers reviewing the S5D-E3/9AT datasheet, S5D-E3/9AT pinout, S5D-E3/9AT application, or S5D-E3/9AT equivalent, key selection considerations include its SMC (DO-214AB) package, low leakage (10 μA at 25 °C), fast recovery (2.5 μs), thermal resistance of 10 °C/W (junction-to-lead), and AEC-Q101 qualification availability in HE3 variants.
Technical Context
This device is a single-junction, silicon planar epitaxial rectifier with glass-passivated chip construction, optimized for high-efficiency AC/DC conversion and inductive load switching. Its 2.5 μs reverse recovery time and 40 pF junction capacitance support operation in medium-frequency switching circuits up to several hundred kHz.
The SMC (DO-214AB) package provides robust thermal performance (RθJL = 10 °C/W on 8 mm × 8 mm copper pad) and meets UL 94 V-0 flammability requirements. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards and JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking capability without breakdown |
| IF(AV) | 5.0 A - continuous DC output current at 100 °C lead temperature |
| IFSM | 100 A - withstands short-duration inrush surges (8.3 ms half-sine) |
| VF | 1.15 V - forward voltage drop at 5.0 A, directly impacts conduction loss and thermal design |
| IR | 10 μA - reverse leakage at 25 °C and rated VDC, critical for standby power integrity |
| trr | 2.5 μs - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; limits switching frequency |
| TJ max. | 175 °C - maximum operating junction temperature enables high-ambient designs |

Applications
| AC/DC Power Supply Rectification | DC Motor Freewheeling |
|---|---|
Use Scenario: Full-wave bridge rectification in offline 115/230 VAC SMPS front-ends delivering 24–48 VDC outputs. IC Role / Device Role / Timing Role: Primary rectifier conducting during positive half-cycles; paired with complementary diodes in bridge configuration. Use Value: 200 V VRRM safely blocks peak line voltage (≈325 V) with margin; 5.0 A IF(AV) supports >60 W continuous output. | Use Scenario: Clamping inductive kickback from brushed DC motors in automotive seat adjusters and HVAC actuators. IC Role / Device Role / Timing Role: Freewheeling diode placed anti-parallel across motor winding to provide current recirculation path during PWM turn-off. Use Value: 100 A IFSM absorbs high-energy flyback pulses; 2.5 μs trr minimizes voltage overshoot and EMI generation. |
| Telecom DC-DC Converter Output Stage | Industrial Inverter Auxiliary Supply |
Use Scenario: Secondary-side synchronous rectification replacement in isolated 48 V telecom brick converters powering base station radios. IC Role / Device Role / Timing Role: Output rectifier converting transformer secondary AC to regulated DC; operates in discontinuous conduction mode. Use Value: 1.15 V VF reduces conduction loss at 5 A load; 175 °C TJ max allows compact layout near hot power stages. | Use Scenario: Auxiliary bias supply in three-phase IGBT inverters for servo drives, deriving +15 V for gate drivers from main DC bus. IC Role / Device Role / Timing Role: Input rectifier feeding unregulated linear regulator or buck converter; handles intermittent high-current pulses. Use Value: Glass passivation ensures stability under vibration and thermal cycling; 10 μA IR preserves regulation accuracy during standby. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06S | 600 V VRRM, 5 A IF(AV), 1.7 V VF, TO-277 package | Higher voltage rating but higher VF increases conduction loss at 200 V systems | Select when system requires >400 V blocking; avoid if efficiency at 200 V is critical |
| ON Semi MUR520 | 200 V VRRM, 5 A IF(AV), 1.25 V VF, DO-201AD package | Larger DO-201AD footprint, higher RθJA, not MSL Level 1 rated | Acceptable for through-hole prototyping or legacy PCBs; not suitable for automated SMT production |
Compared with STTH5L06S and MUR520, the S5D-E3/9AT delivers lower forward loss (1.15 V vs. ≥1.25 V), superior thermal resistance via SMC package, and full MSL Level 1 compliance-making it optimal for high-volume, space-constrained, lead-free SMT power supplies.

FAQ
What is the maximum junction temperature rating for the S5D-E3/9AT?
The S5D-E3/9AT has a maximum junction temperature (TJ max.) of 175 °C, enabling reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. This rating is validated per the Vishay datasheet Document Number 88931 and applies to the S5D-E3/9AT under specified thermal conditions with appropriate PCB copper area.
Does the S5D-E3/9AT have AEC-Q101 qualification?
The S5D-E3/9AT itself is the commercial-grade RoHS-compliant variant (E3 suffix); AEC-Q101 qualification is available only in the HE3 suffix version (e.g., S5DHE3_A/I). The S5D-E3/9AT is not AEC-Q101 qualified, but shares identical die and package construction-only the test screening differs per Vishay's ordering matrix in Document 88931.
What does the "9AT" in S5D-E3/9AT indicate?
The "9AT" suffix denotes the packaging configuration: 13-inch diameter plastic tape-and-reel with 3500 units per reel. It is distinct from "57T", which indicates 7-inch tape-and-reel with 850 units. Both use the same S5D-E3 die and SMC package; only reel size and quantity differ-no electrical or mechanical variation exists between S5D-E3/57T and S5D-E3/9AT.
What is the reverse recovery time (trr) of the S5D-E3/9AT and how is it measured?
The S5D-E3/9AT has a typical reverse recovery time (trr) of 2.5 μs, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per Vishay Document 88931. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly influencing switching losses and EMI in high-frequency rectifier applications.
Can the S5D-E3/9AT be used as a direct replacement for the S5B-E3/9AT in a 100 V design?
No-the S5D-E3/9AT is rated for 200 V VRRM, while the S5B-E3/9AT is rated for 100 V. Substituting S5D-E3/9AT into a 100 V design is electrically safe but may incur unnecessary cost and board space; however, using S5B-E3/9AT in a 200 V circuit would risk catastrophic failure. Always match VRRM to the peak reverse voltage in the application, as defined for the S5D-E3/9AT in its official specifications.
