Product details
Overview
P6SMB10AHE3/52 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 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 signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB10AHE3/52 datasheet, P6SMB10AHE3/52 pinout, P6SMB10AHE3/52 application, or P6SMB10AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
The P6SMB10AHE3/52 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress ESD and inductive switching transients. Its unidirectional configuration enables cathode-referenced clamping on DC rails or forward-biased signal paths.
Designed for repetitive transient suppression under 0.01% duty cycle, it sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and maintains stable breakdown behavior across -65 °C to +150 °C operating junction temperature range. Thermal performance is validated per J-STD-020 MSL level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - Verified avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 14.5 V at 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress. |
| PPPM | 600 W - Peak pulse power handling with standardized 10/1000 μs waveform; defines transient energy absorption capacity. |
| ID (Leakage) | 10 μA max at 8.55 V - Low reverse leakage preserves system efficiency and minimizes standby power loss. |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs board-level thermal design requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case meeting UL 94 V-0 flammability rating. Cathode indicated by band on body; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential node (e.g., ground or return path); defines directionality of clamping action. |
| Cathode | Avalanche conduction terminal / Clamping output | Connected to protected line (e.g., 12 V rail or sensor input); conducts transient current to anode when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - suitable for engine control, ADAS, and infotainment systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 10 V VWM, but rated for 400 W PPPM and higher ID (50 μA max); not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; lacks automotive qualification and tighter leakage spec. | Select SMAJ10A only if AEC-Q101 compliance is unnecessary and cost sensitivity outweighs reliability requirements. |
| 1.5SMC10A | Higher-power SMC package (same VWM/VBR), 1500 W PPPM, larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm), RθJA = 30 °C/W. | Requires PCB real estate and thermal management for higher-energy transients; unsuitable for space-constrained layouts. | Choose 1.5SMC10A only when system-level surge testing exceeds 600 W and board area permits larger package. |
Compared with SMAJ10A and 1.5SMC10A, P6SMB10AHE3/52 uniquely balances automotive qualification, compact SMB footprint, and precise 600 W clamping performance - making it optimal for volume automotive and space-limited industrial designs where reliability and layout efficiency are co-prioritized.

FAQ
What is the clamping voltage of P6SMB10AHE3/52 at its rated peak pulse current?
The P6SMB10AHE3/52 has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during transient events and is guaranteed across the full operating temperature range of -65 °C to +150 °C. The P6SMB10AHE3/52 achieves this with low incremental surge resistance, ensuring minimal voltage overshoot beyond VC.
Is P6SMB10AHE3/52 suitable for automotive applications?
Yes, P6SMB10AHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" suffix (RoHS-compliant and AEC-Q101 qualified). It undergoes stress testing including temperature cycling, high-temperature reverse bias, and mechanical shock per AEC-Q101 Rev D. The P6SMB10AHE3/52 is deployed in body control modules, infotainment power rails, and ADAS sensor interfaces where transient immunity and long-term reliability are mandatory.
What is the standoff voltage (VWM) and why does it matter for P6SMB10AHE3/52?
The standoff voltage (VWM) of P6SMB10AHE3/52 is 8.55 V - the maximum DC or continuous reverse voltage the device blocks without significant conduction. This parameter ensures the P6SMB10AHE3/52 remains inactive during normal operation while providing sufficient margin below its 9.50–10.5 V breakdown range. Selecting VWM ≥ 1.1× nominal line voltage prevents false triggering and leakage-related power loss, especially critical in battery-powered or low-quiescent-current systems.
How does the SMB package of P6SMB10AHE3/52 compare to SMA or SMC in terms of thermal performance?
The SMB (DO-214AA) package of P6SMB10AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W on 0.2" × 0.2" copper pads - higher than SMC's ~30 °C/W but lower than SMA's ~120 °C/W. This makes the P6SMB10AHE3/52 thermally adequate for 600 W pulses at low duty cycles (<0.01%) in compact layouts. Its SMB footprint (4.57 × 3.94 × 2.2 mm) offers better board density than SMC while maintaining superior thermal coupling versus SMA, balancing size and dissipation for mid-power protection.
Can P6SMB10AHE3/52 be used in bidirectional configurations?
No, P6SMB10AHE3/52 is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6SMB10CA) and lack polarity marking. Using P6SMB10AHE3/52 in bidirectional AC or floating signal paths would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection, select P6SMB10CAHE3/52 - which shares the same VWM, VBR, and PPPM ratings but operates symmetrically.
