Product details
Overview
P6SMB13AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for robust overvoltage protection of sensitive electronics. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps transients to ≤18.2 V at 33.0 A peak pulse current (10/1000 µs), delivering 600 W peak pulse power in automotive and industrial signal-line protection.
For engineers reviewing the P6SMB13AHM3/I datasheet, P6SMB13AHM3/I pinout, P6SMB13AHM3/I application, or P6SMB13AHM3/I equivalent, this device is selected for high-reliability transient suppression on DC power rails, sensor interfaces, and MOSFET gate drivers where AEC-Q101 qualification, low clamping voltage, and SMB (DO-214AA) package compatibility are critical design requirements.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 11.1 V), then rapidly avalanches below 18.2 V to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while the M3 suffix confirms halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance.
The P6SMB13AHM3/I is rated for TJ = –65 °C to +150 °C, has RθJA = 100 °C/W, and is qualified to AEC-Q101 - making it suitable for under-hood automotive modules and industrial controllers requiring long-term reliability under thermal cycling and repetitive surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation threshold for consistent clamping behavior |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | ≤18.2 V at 33.0 A (10/1000 µs) - actual worst-case clamping voltage seen by protected IC during surge |
| PPPM | 600 W - peak transient power handling capability without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during fault events |
| TJ max. | +150 °C - maximum junction temperature enabling operation in high-ambient environments like engine control units |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode indicated by band marking; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes current path during reverse-biased clamping |

| Halogen-free, RoHS-compliant (M3) | Meets global environmental compliance mandates and supports lead-free reflow assembly (260 °C peak) |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., inductive switch-off spikes) |
| MSL Level 1 (J-STD-020) | Zero moisture sensitivity - no baking required prior to SMT placement |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control modules from load-dump and alternator ripple transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5B | Same VBR range (12.4–13.7 V), but lower PPPM = 400 W and non-AEC-Q101 rated | Restricted to commercial-grade consumer or computing applications; not qualified for automotive use | Select when cost sensitivity outweighs automotive qualification and 400 W surge capacity suffices |
| 1.5SMC13A | Same electrical specs but in larger SMC (DO-214AB) package; higher thermal mass but 2.5× PCB footprint | Preferred where board space allows and higher thermal dissipation margin is needed for sustained surge duty | Choose if layout permits larger footprint and system-level thermal testing shows benefit from lower RθJA |
Compared with SMAJ13A-E3/5B and 1.5SMC13A, the P6SMB13AHM3/I uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and full 600 W surge capability - making it the optimal choice for space-constrained automotive and industrial designs requiring certified reliability.

FAQ
What is the clamping voltage of the P6SMB13AHM3/I under maximum surge conditions?
The P6SMB13AHM3/I clamps to a maximum of 18.2 V when subjected to its rated 33.0 A peak pulse current (10/1000 µs waveform). This value is measured at the device terminals under standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and represents the upper limit of voltage imposed on protected circuitry during a worst-case transient event. The P6SMB13AHM3/I maintains this clamping performance across its full operating temperature range.
Is the P6SMB13AHM3/I suitable for automotive applications?
Yes, the P6SMB13AHM3/I is AEC-Q101 qualified - explicitly validated for automotive use per the HM3 suffix designation. It meets stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock, and is rated for junction temperatures up to +150 °C. The P6SMB13AHM3/I is commonly deployed in engine control units, body electronics, and ADAS sensor modules where certified reliability is required.
What does the "HM3" suffix indicate in P6SMB13AHM3/I?
The "HM3" suffix in P6SMB13AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and packaging in 13-inch tape-and-reel (I). "H" specifies the reel size (3200 units/reel), "M3" confirms halogen-free and RoHS compliance, and the absence of "B" or "D" indicates this variant belongs to the base P6SMB13A family (not the extended-voltage AEC-Q101 subgroups). The P6SMB13AHM3/I is fully compatible with lead-free reflow processes peaking at 260 °C.
How does the P6SMB13AHM3/I compare to bidirectional TVS diodes?
The P6SMB13AHM3/I is unidirectional and must be installed with correct polarity - cathode toward the protected line - to function as a shunt suppressor. Unlike bidirectional variants (e.g., P6SMB13CA), it blocks forward current above ~1.2 V and only clamps in reverse. This makes the P6SMB13AHM3/I ideal for DC rail protection where polarity is fixed, offering tighter VBR tolerance and identical clamping specs as its bidirectional counterpart but with defined anode/cathode orientation.
What is the maximum leakage current of the P6SMB13AHM3/I at its working voltage?
At its maximum stand-off voltage of 11.1 V (VWM), the P6SMB13AHM3/I exhibits a maximum reverse leakage current (ID) of 5.0 µA at TA = 25 °C. This ultra-low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensor or battery-powered circuits. Leakage remains below 50 µA up to 80 % of VWM, supporting stable operation in precision analog front-ends.
