Product details
Overview
1.5SMC200AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 200 V standoff voltage (VWM), 274 V maximum clamping voltage (VC) at 5.5 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the 1.5SMC200AHE3/57T datasheet, 1.5SMC200AHE3/57T pinout, 1.5SMC200AHE3/57T application, or 1.5SMC200AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and SMC (DO-214AB) package compatibility with automated placement.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its breakdown threshold (VBR = 190–210 V at 1 mA), then clamping transient energy to protect downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and fast response time (<1.0 ns).
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL Level 1 (260 °C reflow peak), it supports high-reliability automotive and industrial applications where repetitive surge immunity and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 171 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping. |
| VBR (Breakdown) | 190–210 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 274 V at IPPM = 5.5 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM | 1500 W - Surge energy handling capacity per 10/1000 μs waveform; enables robust protection against lightning and inductive switching. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm copper pads; informs board-level thermal design requirements. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for under-hood and ADAS power systems. |
| Package | SMC (DO-214AB) - Surface-mount outline with cathode band marking; compatible with standard SMT pick-and-place and reflow profiles. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line; defines directionality and grounding topology. |
| Cathode | Reverse voltage sensing / Clamping output | Connected to higher-potential rail (e.g., battery+); conducts avalanche current to ground during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Supports IEC 61000-4-5 Level 4 (4 kV) surge testing without degradation when properly mounted. |
| AEC-Q101 qualification | Validates suitability for automotive power modules, body control units, and infotainment power supplies. |
| Glass passivated junction | Ensures low leakage (<1 μA at VWM) and stable VBR over 1000-hour HTOL life testing. |
| MSL Level 1 moisture sensitivity | Enables direct use from reel without baking; simplifies manufacturing for high-volume automotive PCB assembly. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system immunity. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs against load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery+ and chassis ground to clamp surges above 171 V. Use Value: Limits voltage to ≤274 V during 10/1000 μs pulses, preventing damage to LDOs, microcontrollers, and CAN transceivers. |
Use Scenario: Shielding 4–20 mA current loop inputs in PLC analog modules from field wiring surges. IC Role / Device Role / Timing Role: TVS connected across input terminals to shunt induced transients before reaching precision op-amps. Use Value: Withstands ≥1500 W surges while maintaining <1 μA leakage at 171 V, preserving loop accuracy and zero-point stability. |
| Telecom DC Power Input Protection | Motor Drive Control Signal Protection |
Use Scenario: Safeguarding -48 V telecom rectifier outputs against lightning-induced surges on outdoor cabinet feeds. IC Role / Device Role / Timing Role: Unidirectional TVS installed at power entry point, cathode to -48 V rail, anode to ground. Use Value: Clamps 10/1000 μs surges to 274 V with <1.0 ns response, meeting GR-1089-CORE Level 3 immunity requirements. |
Use Scenario: Protecting isolated gate driver enable signals in BLDC inverters from cross-talk and MOSFET switching noise. IC Role / Device Role / Timing Role: TVS placed across logic-level signal path (e.g., EN pin to GND) to suppress sub-100 ns spikes. Use Value: Low capacitance and fast response prevent false triggering of gate drivers while maintaining signal integrity up to 1 MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-E3/52 | Lower PPPM (600 W), same VWM (171 V), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Not AEC-Q101 qualified; suitable for commercial-grade consumer power supplies but not automotive. | Select when board space is constrained and surge energy is ≤600 W; verify thermal derating at 100 °C ambient. |
| 1.5KE200A | Through-hole DO-201 package, identical electrical specs (VWM = 171 V, VC = 274 V), no AEC-Q101 qualification | Limited to non-automotive industrial equipment due to leaded packaging and lack of automotive reliability validation. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ200A-E3/52 and 1.5KE200A, the 1.5SMC200AHE3/57T uniquely combines 1500 W surge capability, AEC-Q101 qualification, and SMC surface-mount packaging - making it the only option qualified for production automotive electronics requiring both high energy handling and zero-bake manufacturability.

FAQ
What is the clamping voltage of the 1.5SMC200AHE3/57T under a 10/1000 μs surge?
The 1.5SMC200AHE3/57T has a maximum clamping voltage (VC) of 274 V at 5.5 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The 1.5SMC200AHE3/57T maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC200AHE3/57T qualified for automotive applications?
Yes, the 1.5SMC200AHE3/57T carries the HE3 suffix, indicating RoHS-compliant construction and full AEC-Q101 qualification per Vishay's ordering nomenclature. It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D, making it suitable for under-hood and ADAS power systems where automotive-grade reliability is mandated.
What does the "57T" suffix mean in 1.5SMC200AHE3/57T?
The "57T" suffix in 1.5SMC200AHE3/57T denotes packaging: 7-inch diameter plastic tape-and-reel with 850 units per reel. This format is optimized for high-speed SMT placement equipment and aligns with IPC-7351 standards for SMC (DO-214AB) devices. The "57T" code appears in Vishay's official ordering information table on page 3 of document 88303.
How does the thermal performance of the 1.5SMC200AHE3/57T affect PCB layout?
The 1.5SMC200AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain TJ ≤ 150 °C under worst-case 6.5 W steady-state dissipation, designers must allocate ≥12 cm² total copper area with thermal vias - underscoring why the 1.5SMC200AHE3/57T requires careful thermal pad design, not just electrical routing.
Can the 1.5SMC200AHE3/57T be used in bidirectional configurations?
No - the 1.5SMC200AHE3/57T is strictly unidirectional, as confirmed by its "A" suffix and cathode-band marking per Vishay's mechanical data. For bidirectional protection at ~200 V, the correct variant is 1.5SMC200CAHE3/57T (with "CA" suffix). Using the 1.5SMC200AHE3/57T in reverse-biased AC applications risks catastrophic failure due to lack of symmetrical avalanche structure.
