Product details
Overview
P6SMB10A-M3/5B 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 600 W peak pulse power rating 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 P6SMB10A-M3/5B datasheet, P6SMB10A-M3/5B pinout, P6SMB10A-M3/5B application, or P6SMB10A-M3/5B equivalent, key selection criteria include unidirectional polarity, 10 V stand-off rating, 14.5 V clamping performance under 41.4 A surge, halogen-free RoHS compliance (M3 suffix), and SMB package thermal resistance of 100 °C/W junction-to-ambient.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable breakdown behavior across -65 °C to +150 °C operating junction temperature range.
The device is rated for 600 W peak pulse power (10/1000 μs), 5.0 W steady-state power dissipation, and 100 A non-repetitive forward surge current (8.3 ms half-sine). It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - maximum reverse voltage before clamping begins; defines safe operating window for protected circuit |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - precise voltage threshold where avalanche conduction initiates |
| VC (Clamping) | 14.5 V at 41.4 A IPPM - maximum voltage seen by protected load during worst-case transient |
| PPPM | 600 W - peak transient energy absorption capability with standardized 10/1000 μs waveform |
| IR (Leakage) | 10 μA at VWM - minimal parasitic loading on signal/power line during normal operation |
| TJ max | +150 °C - maximum junction temperature enabling use in high-ambient environments like engine bays |
| RθJA | 100 °C/W - thermal resistance defining temperature rise per watt under standard PCB pad layout |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by band marking on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (unidirectional) | Connected to ground or low-side reference; completes clamping path when cathode is at higher potential |
| Cathode | Current exit terminal (unidirectional) | Connected to protected line; conducts avalanche current to anode during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without derating on standard PCB pads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 10 V VWM, but lower PPPM (400 W) and higher VC (17.0 V at 23.3 A) | Limited to lower-energy transients; not suitable for IEC 61000-4-5 Level 4 or automotive load dump | Select P6SMB10A-M3/5B when 600 W surge handling and tighter clamping (14.5 V vs. 17.0 V) are required. |
| 1.5SMC10A | Higher-power SMC package (1500 W PPPM), same VWM/VC specs, but larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) | Requires PCB redesign; better suited for high-reliability industrial power systems with space margin | Choose P6SMB10A-M3/5B for space-constrained designs where 600 W suffices and SMB footprint is mandatory. |
Compared with SMAJ10A and 1.5SMC10A, P6SMB10A-M3/5B delivers optimal balance of 600 W surge capacity, compact SMB footprint, and 14.5 V clamping - making it preferred for automotive body control modules and industrial PLC I/O cards where board area and clamping precision are critical.

FAQ
What is the standoff voltage rating of the P6SMB10A-M3/5B?
The P6SMB10A-M3/5B has a maximum reverse stand-off voltage (VWM) of 8.55 V at 25 °C. This value ensures the device remains non-conductive during normal operation while allowing sufficient margin below its 9.50–10.5 V breakdown range. The P6SMB10A-M3/5B maintains this rating across its full operating temperature range, supporting stable protection in environments from -65 °C to +150 °C junction temperature.
How does the clamping voltage of P6SMB10A-M3/5B compare to similar 10 V TVS diodes?
The P6SMB10A-M3/5B clamps to a maximum of 14.5 V at 41.4 A peak pulse current (10/1000 μs), which is tighter than alternatives like SMAJ10A (17.0 V at 23.3 A). This lower clamping voltage directly improves system-level surge immunity by reducing stress on downstream 12 V or 15 V-rated components. The P6SMB10A-M3/5B achieves this via optimized silicon geometry and low incremental resistance.
Is P6SMB10A-M3/5B suitable for automotive applications?
Yes - the P6SMB10A-M3/5B is halogen-free and RoHS-compliant (M3 suffix), and AEC-Q101 qualified variants (e.g., P6SMB10AHM3_B) are available. Its 150 °C max junction temperature, 100 A surge rating, and MSL Level 1 rating make it suitable for under-hood and body-control module applications. While P6SMB10A-M3/5B itself is commercial-grade, its design foundation supports automotive qualification paths.
What is the thermal resistance of P6SMB10A-M3/5B, and how does it affect layout?
The P6SMB10A-M3/5B 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 standard SMB pad layout per Vishay's recommended footprint. To maintain safe junction temperatures, designers must ensure adequate copper area and avoid excessive power dissipation beyond 5.0 W continuous rating - especially in enclosed or high-ambient environments.
Does P6SMB10A-M3/5B have bidirectional capability?
No - P6SMB10A-M3/5B is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. For bidirectional operation, Vishay offers the P6SMB10CA variant. Using P6SMB10A-M3/5B in bidirectional circuits requires external configuration (e.g., back-to-back pairing), whereas P6SMB10CA provides symmetrical clamping in a single device. Always verify polarity alignment during PCB layout to prevent reverse-bias failure.
