Product details
Overview
SM6T200AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM = 171 V), 274 V clamping voltage at 2.2 A peak pulse current (10/1000 μs), 600 W peak pulse power, and AEC-Q101 qualified for automotive applications. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients.
For engineers reviewing the SM6T200AHE3/52 datasheet, SM6T200AHE3/52 pinout, SM6T200AHE3/52 application, or SM6T200AHE3/52 equivalent, key selection criteria include unidirectional polarity, 171 V stand-off rating, 274 V clamping performance at 2.2 A, AEC-Q101 qualification status, and SMB package compatibility with automated SMT placement.
Technical Context
The SM6T200AHE3/52 operates as a unidirectional avalanche breakdown device, triggered when reverse voltage exceeds its 190–210 V breakdown range (VBR at 1 mA). Its low-inductance SMB package enables fast response to transients, while glass-passivated junction ensures stable leakage (<1 μA at 171 V) and robust surge handling up to 100 A IFSM (10 ms half-sine).
Thermal design relies on RθJA = 100 °C/W and RθJL = 20 °C/W, requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for full 600 W pulse rating. It meets MSL Level 1 (260 °C reflow peak) and supports automotive-grade reliability via AEC-Q101 qualification under HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Confirmed avalanche initiation range under DC test conditions |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case transient |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability for standardized 10/1000 μs waveform |
| IFSM (Surge Current) | 100 A - Single half-sine 10 ms forward surge rating, critical for inrush or fault-current immunity |
| TJ max. | +150 °C - Maximum junction temperature defining operational and reliability limits |
| Polarity | Unidirectional - Cathode marked with band; blocks forward current, clamps reverse transients |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 60 V) on 12 V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges before they reach downstream regulators and microcontrollers. Use Value: Limits rail voltage to ≤274 V during 2.2 A transient, preventing damage to 36 V-rated input stages of PMICs and CAN transceivers. | Use Scenario: Protecting analog outputs of pressure/temperature sensors in PLC modules exposed to relay coil switching noise. IC Role / Device Role / Timing Role: TVS connected across sensor output and ground to absorb 10/1000 μs inductive spikes coupled onto 4–20 mA or 0–10 V lines. Use Value: Clamps induced spikes to <274 V while maintaining sub-1 μA leakage at 171 V, preserving signal integrity and ADC accuracy. |
| Telecom DC Power Input Protection | Motor Drive Gate Driver ESD Suppression |
Use Scenario: Safeguarding PoE-powered network switches against lightning-induced surges on 48 V DC input ports. IC Role / Device Role / Timing Role: Primary-level TVS on DC input rail upstream of DC/DC converters, coordinated with GDT or MOV secondary protection. Use Value: Absorbs 600 W pulses without degradation, enabling compliance with IEC 61000-4-5 Level 3 (1 kV/2 kV) surge immunity requirements. | Use Scenario: Shielding high-side gate drivers in BLDC inverters from Miller-induced voltage spikes during MOSFET switching. IC Role / Device Role / Timing Role: Local TVS mounted directly at gate driver output pin to clamp dv/dt-induced overshoot before reaching MOSFET gate oxide. Use Value: Fast response (<1 ns) and low clamping voltage (274 V) prevent gate oxide breakdown in 200 V-rated SiC MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/52 | Same VWM (171 V), lower PPPM (400 W), higher VC (291 V at 2.2 A), SMA package (larger footprint) | Less robust for repeated 600 W surges; requires larger PCB area | Select if cost-sensitive and surge duty cycle is light; verify thermal derating on 5 mm² pads |
| 1.5SMC200A | Same VWM (171 V), same PPPM (600 W), but SMC package (DO-214AB); higher RθJA (125 °C/W) | Lower thermal efficiency; not AEC-Q101 qualified | Choose only for non-automotive industrial use where space allows larger SMC footprint and qualification is not required |
Compared with SMAJ200A-E3/52 and 1.5SMC200A, SM6T200AHE3/52 delivers superior automotive qualification, tighter thermal resistance (RθJA = 100 °C/W), and optimized SMB footprint for dense layouts-making it the preferred choice for AEC-Q101-compliant 12/24 V systems requiring repeatable 600 W surge handling.

FAQ
What is the clamping voltage of the SM6T200AHE3/52 under standard test conditions?
The SM6T200AHE3/52 has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at a peak pulse current (IPPM) of 2.2 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during transient events. The SM6T200AHE3/52 maintains this clamping performance across its specified operating temperature range and is validated for AEC-Q101 automotive use.
Is the SM6T200AHE3/52 suitable for automotive applications?
Yes, the SM6T200AHE3/52 is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. It is specifically designed for automotive power rail and signal line protection, including engine control units, body electronics, and ADAS sensor interfaces. The SM6T200AHE3/52 meets MSL Level 1 reflow requirements and is manufactured with RoHS-compliant, whisker-resistant terminations per JESD 201 Class 2.
What package type does the SM6T200AHE3/52 use, and what are its key mechanical features?
The SM6T200AHE3/52 uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.20 mm. Key features include glass passivation for junction stability, matte tin-plated leads compliant with J-STD-002, and UL 94 V-0 rated molding compound. Its low-profile design supports automated placement, and the cathode is marked with a visible band for polarity identification.
How does the SM6T200AHE3/52 differ from bidirectional TVS diodes like SM6T200CA?
The SM6T200AHE3/52 is unidirectional and conducts only in reverse bias above its breakdown voltage, with a defined cathode band. In contrast, SM6T200CA is bidirectional and clamps transients of either polarity. The SM6T200AHE3/52 offers lower leakage at VWM and is preferred for DC power rail protection, whereas SM6T200CA suits AC-coupled or differential signal lines where polarity reversal occurs.
What is the maximum steady-state power dissipation (PD) of the SM6T200AHE3/52?
The SM6T200AHE3/52 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at TA = 50 °C. This rating reflects continuous DC or low-frequency power handling-not transient surge capability. For reliable operation, thermal design must account for RθJA = 100 °C/W and ensure adequate copper pad area (minimum 5.0 mm × 5.0 mm per terminal) to sustain full 600 W pulse ratings.
