Product details
Overview
P6SMB10AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping transient overvoltages on power and signal lines. It features 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 automotive and industrial control systems.
For engineers reviewing the P6SMB10AHE3/5B datasheet, P6SMB10AHE3/5B pinout, P6SMB10AHE3/5B application, or P6SMB10AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, clamping performance under 10/1000 μs surge, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (9.5–10.5 V at 1 mA test current). Its glass-passivated junction ensures stable leakage (<10 μA at 8.55 V) and fast response time (<1.0 ns), enabling protection against ESD, lightning-induced surges, and inductive switching transients.
The P6SMB10AHE3/5B is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). Its AEC-Q101 qualification confirms suitability for automotive electronics where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - precise avalanche initiation range ensuring predictable turn-on during transients |
| VC (Clamping Voltage) | 14.5 V at 41.4 A IPPM - limits downstream voltage stress during 10/1000 μs surge, protecting 12 V rail components |
| PPPM (Peak Pulse Power) | 600 W - sustained energy absorption capability per single 10/1000 μs transient without failure |
| ID (Reverse Leakage) | 10 μA max at VWM - low leakage preserves system efficiency and avoids false triggering in high-impedance circuits |
| TJ max | 150 °C - enables operation in under-hood automotive environments and industrial enclosures without derating |
| RθJA | 100 °C/W - thermal resistance from junction to ambient; requires minimum 0.2" × 0.2" copper pad for rated power handling |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage across temperature (-65 °C to +150 °C) |
| 600 W peak pulse rating (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) in compact SMB footprint |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; compatible with high-volume SMT assembly |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing stress on downstream 12 V logic and analog ICs |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Protection |
|---|---|
|
Use Scenario: Protecting microcontroller GPIOs and CAN transceiver power rails from load dump and alternator ripple in vehicle body electronics. IC Role / Device Role / Timing Role: Unidirectional TVS clamping transient spikes on 12 V supply lines feeding MCU peripherals.

IC Role / Device Role / Timing Role: Fast-response clamp on half-bridge high-side supply rail to suppress inductive kickback. Use Value: Responds in <1 ns to limit voltage overshoot to 14.5 V, preventing unintended IGBT/MOSFET turn-on and shoot-through risk. |
Use Scenario: Suppressing differential-mode surges entering AC-DC power supplies via telecom-grade front-end filters. IC Role / Device Role / Timing Role: Primary-level TVS on secondary-side DC bus before DC-DC converter input. Use Value: Absorbs 600 W pulses without degradation, maintaining 8.55 V standoff to avoid false triggering during normal 12 V regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5B | Same SMB package, 10 V VWM, but lower PPPM (400 W) and higher VC (17.0 V at 24.7 A) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 compliance | Select when cost sensitivity outweighs surge margin and clamping tightness requirements |
| 1.5SMC10A | Higher-power SMC package (1500 W PPPM), same VWM/VC specs, but 2.5× larger footprint and higher RθJA | Requires PCB area reallocation; better for high-repetition surges but over-specified for single-event protection | Choose only if system-level surge testing exceeds 600 W or thermal management is constrained |
Compared with SMAJ10A-E3/5B and 1.5SMC10A, the P6SMB10AHE3/5B delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and minimal SMB footprint - making it preferred for space-constrained automotive and industrial modules requiring validated reliability.

FAQ
What does the "HE3" suffix indicate in P6SMB10AHE3/5B?
The "HE3" suffix in P6SMB10AHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification. This distinguishes it from commercial-grade "E3" variants and confirms validation for automotive applications including temperature cycling, humidity testing, and mechanical shock per AEC-Q101 Rev H requirements. The P6SMB10AHE3/5B meets these standards while retaining identical electrical specs to non-automotive versions.
Is P6SMB10AHE3/5B bidirectional or unidirectional?
P6SMB10AHE3/5B is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and explicit specification of cathode band marking. It conducts only during reverse-biased overvoltage events and must be oriented with the banded end toward the protected line. Bidirectional variants like P6SMB10CA are functionally distinct and not interchangeable with P6SMB10AHE3/5B.
What is the maximum clamping voltage of P6SMB10AHE3/5B and under what conditions is it specified?
The maximum clamping voltage of P6SMB10AHE3/5B is 14.5 V, measured at 41.4 A peak pulse current (IPPM) using a 10/1000 μs double-exponential waveform. This value is guaranteed per Vishay's datasheet (Document Number 88370, Rev 09-Jan-2024) and represents worst-case voltage seen by downstream circuitry during standardized surge events - critical for validating protection margins in 12 V systems.
Can P6SMB10AHE3/5B replace P6SMB10A-E3/5B in existing designs?
Yes, P6SMB10AHE3/5B is a direct functional and mechanical replacement for P6SMB10A-E3/5B, sharing identical electrical characteristics, SMB package dimensions, and pinout. The only enhancement is AEC-Q101 qualification - adding automotive reliability validation without layout or schematic changes. No derating or requalification is needed unless the application explicitly requires AEC-Q101 certification.
What PCB pad layout is required to achieve the rated 600 W pulse power for P6SMB10AHE3/5B?
To achieve the full 600 W peak pulse power rating, P6SMB10AHE3/5B must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay's datasheet Figure 2 and thermal characterization notes. Smaller pads increase thermal resistance and reduce surge capability; use of internal ground planes or thermal vias further improves sustained pulse handling beyond single-event ratings.
