Product details
Overview
P6SMB200AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 274 V clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in industrial power supplies and automotive control units.
For engineers reviewing the P6SMB200AHM3_A/I datasheet, P6SMB200AHM3_A/I pinout, P6SMB200AHM3_A/I application, or P6SMB200AHM3_A/I equivalent, this device delivers verified AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and 150 °C maximum junction temperature - critical for under-hood automotive electronics and high-reliability industrial designs.
Technical Context
This TVS operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated silicon junction technology for stable breakdown behavior and low incremental surge resistance. Its 10/1000 μs waveform response ensures effective suppression of fast-rising transients while maintaining low leakage (<1.0 μA at VWM).
The device exhibits a 0.108 %/°C temperature coefficient of breakdown voltage (VBR), enabling predictable clamping performance across -65 °C to +150 °C operating range. Thermal resistance is specified at RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), supporting reliable operation on standard 0.2" × 0.2" copper pads without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA test current - Confirmed avalanche initiation range; ensures consistent turn-on threshold across production lots. |
| VC (Clamping Voltage) | 274 V at 2.2 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs transient; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustains single 10/1000 μs surge events without failure; validated per Fig. 1 derating curves. |
| ID (Reverse Leakage) | <1.0 μA at 171 V - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +150 °C - Enables deployment in engine control modules and industrial motor drives with elevated ambient temperatures. |
| MSL Level | Level 1 (JEDEC J-STD-020) - Supports standard reflow profiles up to 260 °C peak without preconditioning. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to ground or low-side reference in unidirectional protection. | Provides return path for surge current; must be routed with low-inductance trace to minimize clamping overshoot. |
| Cathode | Protected line connection; carries transient energy into the device during overvoltage events. | Connected directly to I/O line or power rail being safeguarded; polarity-sensitive - reversal disables protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for powertrain and ADAS subsystems. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations - supports green manufacturing and end-of-life compliance. |
| 600 W peak pulse power (10/1000 μs) | Handles repetitive surge events up to 0.01% duty cycle without degradation - suitable for motor drive snubbing and relay coil suppression. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal stress and humidity exposure. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage margin between breakdown and clamping - improves protection headroom for 200 V-rated systems. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Digital Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5B | Same VWM (171 V), VC = 324 V at 1.8 A; lower PPPM (400 W); commercial-grade (not AEC-Q101). | Lacks automotive qualification and halogen-free certification; suitable only for non-automotive industrial use. | Select when cost sensitivity outweighs AEC-Q101 requirement and 324 V clamping is acceptable for system margin. |
| 1.5SMC200AHE3_A | Same VWM/VC specs; higher RθJA (120 °C/W); AEC-Q101 qualified but in larger SMC (DO-214AB) package. | Requires larger PCB area and different pad layout; thermal performance less optimal on minimal copper. | Choose only if existing design uses SMC footprint and board space allows 2.5 mm height increase over SMB. |
Compared with P6SMB200AHM3_A/I, SMAJ200A-E3/5B offers lower cost but sacrifices automotive qualification and clamping performance, while 1.5SMC200AHE3_A maintains qualification at the expense of board space and thermal efficiency - making P6SMB200AHM3_A/I the optimal balance of size, reliability, and surge capability for space-constrained automotive and industrial designs.

FAQ
What is the clamping voltage of P6SMB200AHM3_A/I at its rated peak pulse current?
The P6SMB200AHM3_A/I has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB200AHM3_A/I achieves this with a low clamping ratio of approximately 1.37 relative to its nominal breakdown voltage, ensuring robust protection margin for 200 V-class systems.
Is P6SMB200AHM3_A/I qualified for automotive applications?
Yes, P6SMB200AHM3_A/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024, Doc. #88370). The HM3 designation indicates halogen-free, RoHS-compliant construction with full automotive stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. This makes P6SMB200AHM3_A/I suitable for engine control units, body electronics, and ADAS modules where qualification evidence is mandatory.
What package type does P6SMB200AHM3_A/I use, and what are its key mechanical features?
P6SMB200AHM3_A/I uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.20 mm with matte tin-plated leads. Key mechanical features include UL 94 V-0 flammability rating, J-STD-020 MSL Level 1 rating (peak reflow temperature 260 °C), and compatibility with automated pick-and-place equipment. The cathode is marked by a visible band, and the package is optimized for thermal dissipation on 0.2" × 0.2" copper pads - all verified in Vishay's mechanical drawings and thermal characterization data for the P6SMB Series.
How does the temperature coefficient affect P6SMB200AHM3_A/I's performance across its operating range?
P6SMB200AHM3_A/I has a temperature coefficient of breakdown voltage (VBR) of +0.108 %/°C, meaning VBR increases linearly with junction temperature. At 150 °C, VBR rises ~12.9% above its 25 °C value (190–210 V), extending the clamping window slightly but maintaining safe margin above VWM (171 V). This positive coefficient ensures predictable, monotonic behavior - critical for designs operating near thermal limits, such as under-hood automotive modules. The P6SMB200AHM3_A/I remains fully functional across its -65 °C to +150 °C TJ range without parameter inversion or instability.
Can P6SMB200AHM3_A/I be used in bidirectional configurations?
No, P6SMB200AHM3_A/I is a unidirectional TVS diode, indicated by the "A" suffix (not "CA") and absence of bidirectional VBR/VWM specifications in its row of the Vishay datasheet table. Bidirectional variants like P6SMB200CA exist but have distinct marking codes, electrical characteristics, and no polarity band. Using P6SMB200AHM3_A/I in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection, select a part explicitly designated with "CA" suffix and verified bidirectional parameters - P6SMB200AHM3_A/I is strictly for DC or single-polarity transient suppression.
