Product details
Overview
P6SMB36AHM3_A/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 36 V breakdown voltage (VBR = 34.2–37.8 V at IT = 1.0 mA), 30.8 V stand-off voltage (VWM), and clamps transients to ≤49.9 V at 12.0 A peak pulse current (IPPM) under 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB36AHM3_A/I datasheet, P6SMB36AHM3_A/I pinout, P6SMB36AHM3_A/I application, or P6SMB36AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, SMB (DO-214AA) package with cathode band marking, and 600 W peak pulse power rating - all critical for automotive-grade ESD/surge resilience in harsh environments.
Technical Context
This unidirectional TVS operates as a clamping device that remains high-impedance below VWM = 30.8 V and rapidly avalanches above VBR = 34.2–37.8 V to limit transient voltages. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), and is rated for 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave - confirming suitability for high-energy transient events in automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA test current - defines precise avalanche onset window for reliable clamping threshold control |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA, ensuring no false triggering |
| VC @ IPPM | ≤49.9 V at 12.0 A - clamped voltage during 600 W 10/1000 µs surge, directly limiting stress on downstream ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5B | Same VWM/VBR/VC specs but rated for 400 W PPPM (vs. 600 W); SMB package identical; not AEC-Q101 qualified | Limited to commercial/industrial use; insufficient for automotive load dump validation | Select when cost sensitivity outweighs automotive qualification and 600 W surge margin |
| 1.5SMC36A | Same electrical ratings but in larger SMC (DO-214AB) package; 1.5 kW PPPM rating; AEC-Q101 available only in HE3/HM3 variants | Requires PCB layout change due to 2.54 mm longer body; higher thermal mass improves sustained surge handling | Choose when higher energy absorption (>600 W) or improved thermal derating is required in space-permitting designs |
Compared with SMAJ36A-E3/5B and 1.5SMC36A, P6SMB36AHM3_A/I uniquely delivers AEC-Q101 qualification, 600 W surge capability, and halogen-free compliance in the compact SMB footprint - making it the optimal choice for space-constrained, automotive-grade transient protection where qualification and reliability are non-negotiable.

FAQ
What is the clamping voltage of P6SMB36AHM3_A/I at its rated peak pulse current?
The P6SMB36AHM3_A/I clamps to a maximum of 49.9 V at its rated peak pulse current of 12.0 A under the standard 10/1000 µs waveform. This value is measured per the test conditions defined in the Vishay datasheet (Document Number: 88370, Rev. 09-Jan-2024) and reflects worst-case voltage seen by downstream circuitry during surge events - a critical parameter for ensuring safe operation of protected ICs such as microcontrollers or transceivers.
Is P6SMB36AHM3_A/I qualified for automotive applications?
Yes, P6SMB36AHM3_A/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in the Vishay P6SMB datasheet. The HM3 designation indicates halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing including high-temperature operating life, temperature cycling, and ESD robustness - making P6SMB36AHM3_A/I suitable for under-hood and body electronics in passenger vehicles and commercial vehicles.
What does the "_A/I" suffix mean in P6SMB36AHM3_A/I?
The "_A/I" suffix in P6SMB36AHM3_A/I denotes the packaging configuration: "A" indicates the base part is a unidirectional TVS, and "I" specifies 3200-unit quantity in 13-inch diameter plastic tape and reel - per Vishay's ordering nomenclature in Document Number 88370. This format ensures compatibility with high-speed automated pick-and-place equipment and supports large-volume manufacturing runs without manual handling.
How does P6SMB36AHM3_A/I differ from bidirectional versions like P6SMB36CA?
P6SMB36AHM3_A/I is unidirectional and features a cathode band marking, allowing clamping only for positive transients relative to ground; P6SMB36CA is bidirectional with no polarity marking and clamps both positive and negative excursions. Electrically, P6SMB36AHM3_A/I has VWM = 30.8 V and VBR = 34.2–37.8 V, whereas P6SMB36CA offers symmetric VWM = 30.8 V and VBR = ±34.2–±37.8 V - making P6SMB36AHM3_A/I ideal for DC rail protection and P6SMB36CA better suited for AC-coupled or differential signal lines.
What is the maximum operating junction temperature for P6SMB36AHM3_A/I?
The maximum operating junction temperature for P6SMB36AHM3_A/I is +150 °C, as specified in the "Maximum Ratings" table of the Vishay P6SMB datasheet. This rating is validated across the full operating range (−65 °C to +150 °C) and supports deployment in high-temperature environments such as engine compartments, industrial motor drives, and outdoor telecom enclosures - provided thermal design accounts for RθJA = 100 °C/W (typ.) under standard PCB pad layout.
