Product details
Overview
P6SMB11AHE3/5B 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 9.4 V stand-off voltage (VWM), 10.5–11.6 V breakdown voltage (VBR) at 1 mA, 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and DC power rail surge suppression.
For engineers reviewing the P6SMB11AHE3/5B datasheet, P6SMB11AHE3/5B pinout, P6SMB11AHE3/5B application, or P6SMB11AHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−65 to +150 °C), and RoHS-compliant packaging details for rapid ESD/transient design validation.
Technical Context
The P6SMB11AHE3/5B operates as a unidirectional avalanche diode, leveraging glass-passivated silicon junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping action begins at VWM = 9.4 V and fully engages at VC = 15.6 V under 38.5 A transient current, limiting energy dissipation while maintaining stable reverse leakage (<5 µA).
Designed for surface-mount assembly on 0.2" × 0.2" copper pads per terminal, it meets MSL Level 1 (J-STD-020) with 260 °C reflow peak and supports repetitive surge duty cycles up to 0.01 %. The cathode band marking enables unambiguous polarity identification during automated placement and board-level inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 9.4 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold |
| VBR (Breakdown) | 10.5–11.6 V at 1 mA - Confirmed avalanche initiation range; ensures reliable turn-on during fast transients |
| VC (Clamping) | 15.6 V at 38.5 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; defines safe IC stress limit |
| PPPM | 600 W - Sustained transient energy absorption capability without failure; validated per Fig. 1 derating curve |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard PCB pad layout; determines max ambient temp for 150 °C TJ |
| TJ Range | −65 to +150 °C - Full operational and storage temperature envelope; supports under-hood automotive use |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |

| DC Power Rail Surge Suppression | Consumer Device USB/Power Port Protection |
Use Scenario: Clamping 12 V/24 V supply rails in embedded gateways and telematics units against ISO 16750-2 load dump events. IC Role / Device Role / Timing Role: Primary transient suppressor mounted directly at connector entry point, shunting surge current to ground before reaching downstream regulators. Use Value: Maintains regulated output stability by capping rail voltage at 15.6 V, avoiding brownout or overvoltage shutdown of PMICs and microcontrollers. |
Use Scenario: Protecting USB-C PD port VBUS lines and auxiliary signal pins in portable medical monitors and smart home hubs from ESD and hot-swap transients. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on power path, selected for minimal impact on 5–20 V PD negotiation timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5B | Same SMB package, but lower PPPM (400 W); VC = 18.2 V at 22.5 A; no AEC-Q101 qualification | Limited to commercial-grade consumer/industrial use; insufficient for automotive load dump compliance | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| 1.5SMC11A | Higher-power SMC package (1500 W PPPM); same VWM/VBR specs; larger footprint (7.11 mm × 6.22 mm) | Used where PCB space allows and >600 W surge immunity is required (e.g., industrial motor drives) | Choose for legacy designs using SMC or when upgrading surge margin beyond P6SMB series capability |
Compared with SMAJ11A-E3/5B and 1.5SMC11A, the P6SMB11AHE3/5B uniquely balances AEC-Q101 qualification, 600 W surge capacity, and compact SMB footprint-making it optimal for space-constrained automotive and industrial edge nodes requiring certified reliability without layout redesign.

FAQ
What is the clamping voltage of P6SMB11AHE3/5B at its rated peak pulse current?
The P6SMB11AHE3/5B has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB11AHE3/5B maintains this clamping performance across its full operating temperature range.
Is P6SMB11AHE3/5B qualified for automotive applications?
Yes, the HE3 suffix in P6SMB11AHE3/5B explicitly denotes AEC-Q101 qualification. Vishay validates this part for automotive-grade reliability-including temperature cycling, high-temperature reverse bias (HTRB), and ESD testing-per the AEC-Q101 standard. The P6SMB11AHE3/5B is approved for use in engine control units, ADAS sensors, and body electronics where sustained operation at −65 to +150 °C is required.
What does the "5B" in P6SMB11AHE3/5B indicate?
The "5B" in P6SMB11AHE3/5B specifies the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format is optimized for high-volume SMT production lines using standard 13" feeder systems. The P6SMB11AHE3/5B differs from variants like P6SMB11AHE3/52 (7" reel, 750 units) in reel size, quantity, and handling compatibility-not in electrical or mechanical specifications.
How does P6SMB11AHE3/5B differ from bidirectional versions like P6SMB11CA?
The P6SMB11AHE3/5B is unidirectional, with a cathode band marking and asymmetric conduction: it blocks reverse voltage up to 9.4 V and clamps positive transients above VBR. In contrast, P6SMB11CA is bidirectional, offering symmetrical clamping for AC-coupled or floating signal lines. The P6SMB11AHE3/5B cannot replace P6SMB11CA in applications requiring dual-polarity protection without circuit redesign.
What is the thermal resistance of P6SMB11AHE3/5B, and how does it affect layout?
The P6SMB11AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. This value assumes standard FR-4 PCB construction; reducing RθJA requires increasing copper area or adding thermal vias. For continuous 5.0 W power dissipation, ambient temperature must stay below 100 °C to keep junction temperature within the 150 °C limit. Layout directly impacts P6SMB11AHE3/5B's surge endurance and long-term reliability.
