Product details
Overview
P6SMB130AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control modules.
For engineers reviewing the P6SMB130AHM3_B/H datasheet, P6SMB130AHM3_B/H pinout, P6SMB130AHM3_B/H application, or P6SMB130AHM3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), clamping performance under repetitive surge conditions, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during ESD or inductive switching events.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The HM3 suffix confirms halogen-free, RoHS-compliant construction with AEC-Q101 qualification - verified for automotive-grade reliability in engine control units and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA test current - precise avalanche threshold ensuring predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 179 V at 3.4 A IPPM - limits transient voltage seen by downstream circuitry to protect 150 V-rated components |
| PPPM (Peak Pulse Power) | 600 W with 10/1000 μs waveform - sustains high-energy surges common in automotive load-dump and industrial switching noise |
| RθJA | 100 °C/W - thermal resistance from junction to ambient; requires minimum 0.2" × 0.2" copper pad per terminal for rated power dissipation |
| TJ max. | 150 °C - maximum junction temperature enabling operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive applications including powertrain and chassis systems per stress test requirements |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/5B | Same VWM (111 V), VC = 179 V, but rated for 400 W PPPM and non-AEC-Q101 commercial grade | Lacks automotive qualification; suitable for industrial/commercial power supplies only | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive reliability validation |
| 1.5SMC130AHE3_A/H | Higher package thermal resistance (RθJA = 125 °C/W), same VWM/VC, but uses larger SMC (DO-214AB) package | Requires more PCB area; better suited for higher average power dissipation scenarios | Choose when board layout allows larger footprint and thermal management demands exceed SMB capability |
Compared with P6SMB130AHM3_B/H, SMAJ130A-E3/5B offers lower surge rating and no automotive qualification, while 1.5SMC130AHE3_A/H provides higher thermal mass at the cost of increased board area - making P6SMB130AHM3_B/H optimal for space-constrained AEC-Q101 designs requiring 600 W clamping.

FAQ
What is the clamping voltage of P6SMB130AHM3_B/H at its rated peak pulse current?
The P6SMB130AHM3_B/H has a maximum clamping voltage (VC) of 179 V at 3.4 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB130AHM3_B/H maintains this clamping performance across its operational temperature range and after repeated surge cycles, provided thermal derating guidelines are followed.
Is P6SMB130AHM3_B/H suitable for automotive applications?
Yes, P6SMB130AHM3_B/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and Vishay documentation. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance per automotive reliability standards. The P6SMB130AHM3_B/H is deployed in engine control units, body control modules, and ADAS sensor power rails where sustained operation at 150 °C junction temperature and immunity to load-dump transients are required.
What does the "_B/H" suffix indicate in P6SMB130AHM3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB130AHM3_B/H series (applicable to models from P6SMB6.8A through P6SMB220A), while "_H" specifies 7-inch plastic tape-and-reel packaging with 750 units per reel. The "HM3" portion confirms halogen-free, RoHS-compliant construction. Together, P6SMB130AHM3_B/H identifies a fully automotive-qualified, environmentally compliant, surface-mount TVS diode supplied in standard SMT-ready packaging.
How does P6SMB130AHM3_B/H compare to bidirectional TVS diodes in the same series?
P6SMB130AHM3_B/H is unidirectional, meaning it clamps only reverse-polarity transients and conducts forward current like a rectifier. Bidirectional variants (e.g., P6SMB130CA) suppress both polarities but exhibit higher leakage and slightly reduced clamping efficiency. The P6SMB130AHM3_B/H is preferred for DC power rail protection where polarity is fixed, offering tighter VBR tolerance and lower ID at VWM - critical for low-power standby circuits.
What PCB layout guidance applies to P6SMB130AHM3_B/H for optimal thermal performance?
For rated 600 W pulse power handling, P6SMB130AHM3_B/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's thermal characterization. Trace width should be ≥20 mils, and internal ground/power planes should connect directly to pads via multiple thermal vias. The P6SMB130AHM3_B/H thermal resistance (RθJA = 100 °C/W) assumes this layout; smaller pads increase junction temperature and reduce surge survivability.
