Product details
Overview
P6SMB10A-E3/5B 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 capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB10A-E3/5B datasheet, P6SMB10A-E3/5B pinout, P6SMB10A-E3/5B application, or P6SMB10A-E3/5B equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, IPPM derating above 25 °C, unidirectional polarity marking, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode operates as a reverse-biased avalanche clamp: under normal conditions it presents high impedance (<10 μA leakage at 8.55 V), but triggers rapidly (<1 ns response) when transient voltage exceeds its 9.5–10.5 V breakdown range (tested at 1 mA). Its low incremental surge resistance ensures minimal voltage overshoot during 600 W pulses.
The device uses glass-passivated silicon junction technology, rated for -65 °C to +150 °C junction temperature, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is not AEC-Q101 qualified - the "B" suffix in P6SMB10A-E3/5B denotes tape-and-reel packaging only, not automotive qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - maximum continuous reverse voltage before significant leakage; sets upper limit for protected line DC operating voltage |
| VBR (Breakdown) | 9.5–10.5 V at 1 mA - guaranteed avalanche initiation range; defines minimum overvoltage threshold for clamping action |
| VC (Clamping) | 14.5 V at 41.4 A - maximum voltage seen by downstream circuit during 10/1000 μs transient; must be below protected device absolute max rating |
| PPPM | 600 W - peak transient power dissipation capability; determines survivability against common lightning/surge waveforms |
| IPPM | 41.4 A - peak pulse current corresponding to VC; used with PCB trace width and thermal pad design to manage joule heating |
| TJ max | +150 °C - maximum junction temperature; requires thermal pad layout per 0.2" × 0.2" copper per terminal for full power rating |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance; confirms need for copper thermal relief in non-infinite heatsink layouts |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case meeting UL 94 V-0. Cathode indicated by band; anode and cathode terminals are co-planar, matte tin plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VAK > VBR |
| Anode | Reference node | Typically tied to system ground or lowest potential rail; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) without derating in standard PCB layouts |
| 14.5 V clamping at 41.4 A | Provides ≥15% margin below typical 16.5 V absolute max rating of 12 V rail MOSFETs and logic ICs |
| Glass passivated junction | Ensures stable VBR and low leakage over 10+ year field life, even under humidity and thermal cycling stress |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free assembly without pre-baking or special handling requirements |
| RoHS-compliant, matte tin plating | Guarantees solder joint reliability and intermetallic formation control per JESD22-B102, Class 2 whisker resistance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A (Bourns) | Same SMB package, identical VWM/VC specs (8.55 V / 14.5 V), but lower 400 W PPPM rating | Limited to lower-energy transients (e.g., ESD-only); insufficient for IEC 61000-4-5 line surges | Select when cost sensitivity outweighs surge margin and layout space allows parallel devices |
| 1.5SMC10A (ON Semiconductor) | Same electrical specs and SMB footprint, but higher RθJA (125 °C/W) and no MSL Level 1 rating | Requires pre-bake for lead-free reflow; less suitable for high-volume automated SMT lines | Choose only if legacy BOM alignment or dual-sourcing mandates ON Semi second source |
Compared with SMAJ10A and 1.5SMC10A, P6SMB10A-E3/5B delivers superior surge endurance (600 W vs. 400 W/600 W), guaranteed MSL Level 1 compatibility, and tighter VBR tolerance (±5% vs. ±5%/±6.5%), making it preferred for industrial-grade power rail protection where long-term reliability is critical.

FAQ
What is the maximum clamping voltage of the P6SMB10A-E3/5B under standard test conditions?
The P6SMB10A-E3/5B has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 41.4 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads per terminal), and represents the highest voltage the protected circuit will experience during a transient event. The P6SMB10A-E3/5B maintains this clamping performance across its operational temperature range when properly thermally managed.
Is the P6SMB10A-E3/5B AEC-Q101 qualified?
No, the P6SMB10A-E3/5B is not AEC-Q101 qualified. The "B" suffix in the part number denotes 13-inch tape-and-reel packaging (3200 units per reel), not automotive qualification. AEC-Q101 variants carry "HE3_B" or "HM3_B" suffixes (e.g., P6SMB10AHE3_B). The P6SMB10A-E3/5B is commercial-grade, RoHS-compliant, and rated for -65 °C to +150 °C operation, but lacks the extended lifetime testing and failure analysis required for automotive use. For automotive designs, specify P6SMB10AHE3_B instead of P6SMB10A-E3/5B.
How does the P6SMB10A-E3/5B differ from bidirectional variants like P6SMB10CA?
The P6SMB10A-E3/5B is unidirectional, meaning it conducts only in reverse bias (cathode to anode) and blocks forward current beyond ~3.5 V. In contrast, P6SMB10CA is bidirectional and symmetrical - it clamps transients of either polarity with identical VWM (8.55 V) and VC (14.5 V) in both directions. The P6SMB10A-E3/5B requires correct polarity placement (banded end toward protected line), whereas P6SMB10CA has no polarity marking and can be used on AC-coupled or floating lines. Use P6SMB10A-E3/5B for DC rails; choose P6SMB10CA for differential signal lines or AC inputs.
What is the thermal resistance and how does it affect PCB layout for the P6SMB10A-E3/5B?
The P6SMB10A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Exceeding this thermal resistance - due to undersized pads, lack of internal planes, or poor airflow - causes junction temperature to rise faster during repetitive surges, potentially degrading clamping performance or shortening lifetime. To maintain full 600 W rating, the P6SMB10A-E3/5B must be placed on thermally optimized land patterns with direct copper connections to inner-layer ground/power planes, not isolated traces.
Can the P6SMB10A-E3/5B be used in parallel to increase surge current handling?
No, the P6SMB10A-E3/5B should not be paralleled to increase surge current capacity. Due to manufacturing tolerances in VBR (9.5–10.5 V), mismatched avalanche turn-on causes current hogging - one device absorbs most of the transient energy and fails prematurely while the other remains inactive. Vishay does not characterize or guarantee parallel operation for the P6SMB10A-E3/5B. For higher surge ratings, select a higher-power TVS (e.g., 1.5KE10A) or use a multi-stage protection scheme with upstream current-limiting resistors and downstream low-capacitance TVS devices.
