Product details
Overview
P6SMB100AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects power rails and signal lines in automotive and industrial electronics against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB100AHE3_A/H datasheet, P6SMB100AHE3_A/H pinout, P6SMB100AHE3_A/H application, or P6SMB100AHE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable breakdown behavior and low incremental surge resistance. Its 100 V stand-off voltage ensures reliable blocking during normal operation while responding within picoseconds to transient overvoltages.
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform at 0.01 % duty cycle, with thermal derating above 25 °C per Fig. 2 and junction temperature limits of −65 °C to +150 °C. It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on under surge |
| VC (Clamping Voltage) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during full-rated surge event |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Surge energy absorption capability without failure under standardized waveform |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal DC leakage preserves efficiency in high-impedance bias networks |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements on 0.2" × 0.2" copper pads |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load-dump transients up to 35 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery input and DC-DC converter input stage.

Use Scenario: Brushed DC motor control boards in washing machines, where commutation spikes exceed 200 V. IC Role / Device Role / Timing Role: TVS across motor terminals and H-bridge supply rails to suppress inductive kickback. Use Value: Clamps repetitive 100–200 V spikes to ≤137 V, extending MOSFET lifetime and reducing EMI filter component stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/52 | Same VWM (85.5 V), lower PPPM (400 W), higher RθJA (150 °C/W), no AEC-Q101 qualification | Commercial-grade only; unsuitable for automotive underhood environments | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is not required |
| 1.5SMC100A | Same VWM and VC, but in larger SMC (DO-214AB) package; higher IFSM (200 A), same PPPM (600 W) | Requires larger PCB footprint; better thermal dissipation in high-ambient-temp industrial enclosures | Choose when board space allows and enhanced surge current margin (e.g., for 8.3 ms half-sine IFSM = 100 A) is critical |
Compared with SMAJ100A-E3/52 and 1.5SMC100A, P6SMB100AHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W rating-making it optimal for space-constrained automotive modules needing validated reliability and high-energy clamping.

FAQ
What is the clamping voltage of P6SMB100AHE3_A/H at its rated peak pulse current?
The P6SMB100AHE3_A/H has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current (IPPM) of 4.4 A under the standard 10/1000 μs waveform. This value is measured per test conditions defined in the Vishay datasheet (Document Number: 88370) and reflects worst-case voltage seen by protected circuitry during full-rated surge events. The P6SMB100AHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is P6SMB100AHE3_A/H qualified for automotive applications?
Yes, P6SMB100AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in the Vishay P6SMB series datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness, validating its use in automotive powertrain, body electronics, and ADAS modules. The P6SMB100AHE3_A/H meets the reliability requirements for under-hood and cabin-mounted ECUs.
What is the thermal resistance of P6SMB100AHE3_A/H, and how does it affect PCB layout?
The P6SMB100AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per the datasheet; reducing pad area increases RθJA and risks thermal runaway during repetitive surges. For sustained surge duty, designers should maintain these pad dimensions and avoid excessive copper removal near the SMB footprint. The P6SMB100AHE3_A/H thermal performance is optimized for standard FR-4 boards without additional heatsinking.
How does the glass passivation in P6SMB100AHE3_A/H improve long-term reliability?
Glass passivation of the silicon junction in P6SMB100AHE3_A/H provides a hermetic barrier against moisture ingress and environmental contaminants, preventing parameter drift and premature failure due to corrosion or surface conduction paths. This construction ensures stable breakdown voltage (VBR) and low leakage current (ID) over 15+ years in humid or thermally cycled environments-critical for automotive and industrial deployments. The P6SMB100AHE3_A/H leverages this process to meet AEC-Q101's lifetime reliability requirements.
Can P6SMB100AHE3_A/H be used in bidirectional configurations?
No, P6SMB100AHE3_A/H is a unidirectional TVS diode, as indicated by the "A" suffix and cathode-band marking. Bidirectional variants in the same series use the "CA" suffix (e.g., P6SMB100CA). Using P6SMB100AHE3_A/H in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. For symmetric surge protection, select the correctly marked bidirectional part-not the P6SMB100AHE3_A/H.
