Product details
Overview
P6SMB15AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 15 V breakdown voltage (VBR = 14.3–15.8 V at 1 mA), 21.2 V maximum clamping voltage (VC) at 28.3 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for overvoltage protection of MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the P6SMB15AHE3/52 datasheet, P6SMB15AHE3/52 pinout, P6SMB15AHE3/52 application, or P6SMB15AHE3/52 equivalent, this AEC-Q101 qualified device delivers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and load-switching transient suppression.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 12.8 V, it avalanches to clamp transients up to 21.2 V while conducting up to 28.3 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), and its thermal resistance (RθJA = 100 °C/W) supports operation up to TJ = 150 °C.
The device uses standard SMB (DO-214AA) packaging with matte tin-plated leads, meets J-STD-002 solderability, and is qualified per AEC-Q101 - confirming suitability for automotive under-hood and infotainment subsystems where repetitive surge immunity and long-term reliability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at IT = 1 mA - defines precise avalanche onset threshold for predictable clamping initiation |
| VWM | 12.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 21.2 V at 28.3 A (10/1000 μs) - actual worst-case clamped voltage seen by protected circuit during surge |
| PPPM | 600 W - peak transient power handling capability under standardized surge waveform |
| IPPM | 28.3 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max. | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/52 | Same VBR range (14.3–15.8 V) but lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and surge energy remains ≤400 W |
| 1.5SMC15A | Same electrical specs but SMC (DO-214AB) package - larger body (7.11 mm × 6.22 mm), lower RθJA = 60 °C/W | Better thermal performance for high-duty-cycle environments; incompatible PCB footprint | Choose when thermal margin is critical and layout allows larger pad area |
Compared with SMAJ15A-E3/52 and 1.5SMC15A, P6SMB15AHE3/52 uniquely balances AEC-Q101 qualification, 600 W surge capacity, and SMB footprint - making it optimal for automotive and space-constrained industrial designs requiring certified reliability.

FAQ
What is the clamping voltage of P6SMB15AHE3/52 under maximum surge conditions?
The P6SMB15AHE3/52 clamps to a maximum of 21.2 V when subjected to its rated peak pulse current of 28.3 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during such a transient event. The clamping voltage is guaranteed across the full operating temperature range and confirms effective protection for 12 V systems.
Is P6SMB15AHE3/52 suitable for automotive applications?
Yes, P6SMB15AHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It meets stringent requirements for temperature cycling, humidity resistance, and surge endurance - validated for under-hood and cabin applications including body control modules, infotainment power supplies, and sensor front-ends where reliability under repeated transients is mandatory.
What does the "HE3" suffix indicate in P6SMB15AHE3/52?
The "HE3" suffix in P6SMB15AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and packaging in 7" plastic tape and reel (ordering code "52"). It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive reliability testing, including extended temperature operation and mechanical shock resistance per AEC specifications.
How does P6SMB15AHE3/52 differ from bidirectional versions like P6SMB15CA?
P6SMB15AHE3/52 is unidirectional and features a cathode band for polarity-sensitive placement, while P6SMB15CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional P6SMB15AHE3/52 offers lower leakage (<1 μA at 12.8 V) and is preferred for DC power rail protection, whereas the bidirectional version suits AC-coupled or floating signal lines where polarity reversal may occur.
What is the thermal resistance of P6SMB15AHE3/52, and how does it affect layout?
P6SMB15AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surges, PCB layout must adhere to this pad size - reducing copper area increases thermal impedance and risks exceeding the +150 °C maximum junction temperature during sustained operation.
