Product details
Overview
SM15T200AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 274 V maximum clamping voltage at 5.5 A IPPM, and 171 V stand-off voltage - designed to protect automotive-grade power rails and I/O lines against lightning-induced surges and inductive switching transients.
For engineers reviewing the SM15T200AHE3/57T datasheet, SM15T200AHE3/57T pinout, SM15T200AHE3/57T application, or SM15T200AHE3/57T equivalent, key selection criteria include verified clamping performance at rated IPPM, AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 75 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 190–210 V breakdown (VBR), it avalanches to limit transient energy across protected circuit nodes. Its low-inductance SMC package and glass-passivated junction enable fast response (<1 ns) and stable clamping under repetitive surge stress.
Designed for high-impedance source environments, SM15T200AHE3/57T sustains 5.5 A peak pulse current (IPPM) at 274 V clamping while dissipating 1500 W for 10/1000 μs - with failure mode specified as short-circuit under overstress, ensuring system-level fault containment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains single lightning-surge events without degradation under standard mounting |
| Stand-off Voltage (VWM) | 171 V - maximum continuous reverse voltage before leakage exceeds 1 μA |
| Breakdown Voltage (VBR) | 190–210 V at 1 mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage (VC) | 274 V at 5.5 A IPPM - limits transient voltage seen by downstream ICs or MOSFETs |
| Operating Temperature | -65 °C to +150 °C - supports under-hood automotive and industrial ambient conditions |
| Thermal Resistance (RθJA) | 75 °C/W - defines junction-to-ambient temperature rise under 6.5 W steady-state dissipation |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, H3TRB, and TCT |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse rating | Enables protection against IEC 61000-4-5 Level 4 (4 kV) surges on 50 Ω source impedance lines |
| Glass-passivated junction | Ensures stable VBR and low leakage (<1 μA at VWM) over lifetime and temperature cycling |
| Low-inductance SMC package | Minimizes voltage overshoot during <1 ns transient rise times typical of ESD and lightning coupling |
| AEC-Q101 qualification (HE3 suffix) | Validates reliability for automotive powertrain, body control, and ADAS subsystems |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and lead-free reflow up to 260 °C peak without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ200A | Same 200 V VWM, 274 V VC, but rated for 400 W (SMA package); lower IPPM (3.5 A) | Not AEC-Q101 qualified; suitable for commercial-grade consumer/industrial use only | Select when cost sensitivity outweighs automotive qualification and surge margin |
| ON Semiconductor 1.5SMC200A | Identical electrical specs (171 V VWM, 274 V VC, 1500 W), same SMC package, but AEC-Q101 not confirmed in public documentation | Used in non-automotive industrial designs where qualification traceability is not mandated | Choose if dual-sourcing from multiple franchises is required and AEC-Q101 evidence is not contractually enforced |
Compared with SM15T200AHE3/57T, SMAJ200A offers lower surge capacity and no automotive qualification, while 1.5SMC200A matches electrical performance but lacks publicly documented AEC-Q101 validation - making SM15T200AHE3/57T the only option with guaranteed automotive-grade reliability and full 1500 W capability in SMC form factor.

FAQ
What is the clamping voltage of SM15T200AHE3/57T at its rated peak pulse current?
The SM15T200AHE3/57T has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current (IPPM) of 5.5 A under the standardized 10/1000 μs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal, and defines the upper voltage limit imposed on protected circuits during surge events.
Is SM15T200AHE3/57T qualified for automotive applications?
Yes, SM15T200AHE3/57T carries the HE3 suffix, which denotes RoHS-compliant construction and full AEC-Q101 qualification. Test reports cover HTGB, H3TRB, TCT, and mechanical stress validation - confirming suitability for under-hood and body electronics in passenger vehicles and commercial vehicles.
What does the "57T" in SM15T200AHE3/57T indicate?
The "57T" suffix specifies the packaging configuration: 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel. This format supports automated SMT placement and is compatible with standard pick-and-place equipment used in high-volume electronics manufacturing.
How does SM15T200AHE3/57T differ from bidirectional variants like SM15T200CA?
SM15T200AHE3/57T is unidirectional with cathode band marking and conducts only in reverse avalanche; SM15T200CA is bidirectional, symmetrical in both directions, and lacks polarity marking. The unidirectional version offers tighter leakage control (<1 μA at 171 V) and is preferred for DC rail protection, whereas the bidirectional type suits AC-coupled or floating signal lines.
What is the thermal resistance and maximum power dissipation of SM15T200AHE3/57T?
SM15T200AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a steady-state power dissipation (PD) rating of 6.5 W at TA = 50 °C on an infinite heatsink. These values assume standard SMC mounting on recommended copper pad areas and define safe continuous operating limits outside transient conditions.
