Product details
Overview
P6SMB11AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 11 V breakdown voltage (VBR min/max = 10.5–11.6 V at IT = 1.0 mA), 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current, and 600 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs and sensor signal lines in automotive ECUs.
For engineers reviewing the P6SMB11AHE3_A/I datasheet, P6SMB11AHE3_A/I pinout, P6SMB11AHE3_A/I application, or P6SMB11AHE3_A/I equivalent, this device is selected for robust ESD and surge protection in AEC-Q101-qualified automotive subsystems where low-leakage (<5 µA at VWM), fast response time, and stable clamping under repetitive transients are critical.
Technical Context
This unidirectional TVS diode operates as a reverse-biased avalanche clamp: when transient voltage exceeds VWM (9.4 V), it enters breakdown near VBR (10.5–11.6 V) and limits downstream voltage to ≤15.6 V at 38.5 A. Its glass-passivated junction ensures stable leakage (<5 µA) and long-term reliability under thermal cycling.
Designed for surface-mount assembly on SMB (DO-214AA) footprint, it delivers 600 W peak pulse power with 0.01% duty cycle, 100 °C/W junction-to-ambient thermal resistance, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 9.4 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 10.5–11.6 V at 1.0 mA - Tight tolerance range ensures predictable turn-on during transients; enables precise overvoltage threshold setting. |
| VC (Clamping) | 15.6 V at 38.5 A (10/1000 µs) - Limits protected circuit voltage during worst-case surge; compatible with 12 V automotive rail systems. |
| IPPM | 38.5 A - Peak surge current handling capacity; supports high-energy lightning-induced or inductive-switching transients. |
| PPPM | 600 W - Sustains short-duration surges without failure; validated per IEC 61000-4-5 (10/1000 µs waveform). |
| ID (Leakage) | <5.0 µA at VWM - Minimal standby power loss and signal integrity impact in always-on sensor interfaces. |
| TJ max | +150 °C - Enables operation in under-hood automotive environments with extended thermal margin. |
Pinout & Package
Package: SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.130" body, matte tin-plated leads, UL 94 V-0 molding compound, and MSL Level 1 rating (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VAK > VBR; polarity must be observed for unidirectional operation. |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane; completes clamping loop during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control, ADAS, and body electronics. |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation when mounted per recommended 0.2" × 0.2" copper pads. |
| Glass passivated junction | Ensures stable VBR and low leakage over 15-year automotive service life; resists humidity-induced parameter drift. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving protection margin for downstream ICs. |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; reduces manufacturing cost and avoids moisture-related popcorning failures. |
Applications
| Automotive Power Rail Protection | Sensor Signal Line Clamping |
|---|---|

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-E3/5T | Same VWM/VBR/VC specs but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Not AEC-Q101 qualified; suitable for commercial industrial boards but not automotive under-hood use. | Select when space-constrained layouts require smaller SMA package and automotive qualification is unnecessary. |
| 1.5SMC11A | Same electrical specs and AEC-Q101 option available (1.5SMC11AHM3), but larger SMC (DO-214AB) package with higher thermal mass. | Higher IFSM (200 A vs. 100 A) and lower RθJA (75 °C/W) support higher surge repetition rates in motor drives. | Choose for high-duty-cycle surge environments where thermal dissipation outweighs board space constraints. |
Compared with SMAJ11A-E3/5T, P6SMB11AHE3_A/I offers 50% higher surge power and automotive qualification; versus 1.5SMC11A, it saves PCB area with SMB footprint while retaining AEC-Q101 compliance and sufficient thermal performance for most ECU applications.

FAQ
What is the maximum clamping voltage of the P6SMB11AHE3_A/I under a 10/1000 µs surge?
The P6SMB11AHE3_A/I has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 38.5 A with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB11AHE3_A/I maintains this clamping performance across its qualified operating temperature range.
Is the P6SMB11AHE3_A/I qualified for automotive applications?
Yes, the P6SMB11AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and confirmed in Vishay's ordering information and mechanical data tables. It undergoes stress testing for temperature cycling, high-temperature reverse bias, and surge endurance per automotive reliability standards. The P6SMB11AHE3_A/I is approved for use in engine control, body electronics, and ADAS subsystems where qualification is mandatory.
What does the "A/I" suffix mean in P6SMB11AHE3_A/I?
The "A/I" suffix in P6SMB11AHE3_A/I specifies packaging and reel configuration: "A" denotes the standard SMB (DO-214AA) package variant, and "I" indicates 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel. This format supports high-volume SMT placement and is documented in Vishay's ordering information table for the P6SMB Series. The P6SMB11AHE3_A/I is RoHS-compliant and AEC-Q101 qualified per its HE3 base designation.
How does the P6SMB11AHE3_A/I compare to bidirectional TVS diodes like P6SMB11CA?
The P6SMB11AHE3_A/I is unidirectional and conducts only in reverse bias above VBR, making it ideal for DC power rail protection where polarity is fixed. In contrast, P6SMB11CA is bidirectional with symmetrical clamping in both directions, suited for AC lines or differential signal pairs. The P6SMB11AHE3_A/I offers identical VWM, VBR, and VC values as its bidirectional counterpart but requires correct cathode orientation during layout - a key design consideration absent in bidirectional variants.
What is the thermal resistance of the P6SMB11AHE3_A/I, and how does it affect layout?
The P6SMB11AHE3_A/I 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 JEDEC test conditions and directly impacts sustained surge capability: larger copper areas reduce RθJA, lowering junction temperature rise during repetitive transients. For automotive applications with frequent surges, designers should follow Vishay's pad layout guidelines to ensure the P6SMB11AHE3_A/I remains within its 150 °C TJ(max) limit.
