Product details
Overview
P6SMB15AHE3_B/I 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 15 V breakdown voltage (VBR = 14.3–15.8 V at 1 mA), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the P6SMB15AHE3_B/I datasheet, P6SMB15AHE3_B/I pinout, P6SMB15AHE3_B/I application, or P6SMB15AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by transient overvoltage events. Its glass-passivated junction ensures stable breakdown behavior, while the unidirectional configuration provides forward conduction only during reverse overvoltage surges - critical for DC power rail protection where polarity must be preserved.
The device delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive applications, confirmed by the "HE3" and "_B" suffixes in the part number.

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-E3/5B | Same VBR range (14.3–15.8 V), but SMA package (DO-214AC); 400 W PPPM, higher RθJA (140 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump requiring 600 W | Select when board space allows larger footprint and thermal budget permits higher junction rise |
| 1.5SMC15A | Same electrical specs, but SMC (DO-214AB) package; 600 W rating, but no AEC-Q101 qualification | Not approved for automotive use; requires additional qualification effort for OEM programs | Choose for cost-sensitive industrial designs where automotive qualification is unnecessary |
Compared with SMAJ15A-E3/5B and 1.5SMC15A, P6SMB15AHE3_B/I uniquely combines 600 W surge capability, AEC-Q101 qualification, and SMB footprint - making it the only drop-in option for automotive SMT lines requiring both performance and compliance without layout change.

FAQ
What is the clamping voltage of P6SMB15AHE3_B/I at its rated peak pulse current?
The P6SMB15AHE3_B/I has a maximum clamping voltage (VC) of 21.2 V at its rated peak pulse current (IPPM) of 28.3 A, measured under the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The clamping performance is guaranteed across the full operating temperature range and is validated per AEC-Q101 test conditions for the P6SMB15AHE3_B/I variant.
Is P6SMB15AHE3_B/I suitable for automotive applications?
Yes, P6SMB15AHE3_B/I is explicitly AEC-Q101 qualified, as confirmed by the "HE3" (RoHS-compliant + AEC-Q101) and "_B" (AEC-Q101 grade for 6.8–220 V range) suffixes. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and surge endurance - making it approved for under-hood and body-control module use. The P6SMB15AHE3_B/I meets all requirements for ISO 7637-2 and ISO 16750-2 compliance when applied per Vishay's recommended layout.
What does the "I" suffix mean in P6SMB15AHE3_B/I?
The "I" suffix in P6SMB15AHE3_B/I denotes packaging in a 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume automated SMT placement and is compatible with industry-standard pick-and-place equipment. The "I" designation is distinct from "H" (7-inch reel, 750 units) and does not affect electrical or reliability specifications - the P6SMB15AHE3_B/I retains identical TVS performance and AEC-Q101 qualification as other HE3_B variants.
How does P6SMB15AHE3_B/I differ from non-AEC-Q101 versions like P6SMB15AE3?
P6SMB15AHE3_B/I includes full AEC-Q101 qualification, extended temperature validation (−65 °C to +150 °C), and enhanced process controls for automotive use - whereas P6SMB15AE3 is commercial-grade only. The P6SMB15AHE3_B/I also features tighter VBR distribution, improved surge lifetime, and traceable lot documentation required by Tier 1 OEMs. Electrically identical, the P6SMB15AHE3_B/I adds compliance without trade-offs in clamping or power rating.
What PCB layout guidance applies to P6SMB15AHE3_B/I for optimal surge performance?
For optimal transient suppression, P6SMB15AHE3_B/I must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the datasheet. Short, wide traces to ground/power planes reduce inductance and minimize let-through voltage. Thermal vias under pads improve heat dissipation during repetitive surges. The P6SMB15AHE3_B/I layout must avoid routing sensitive signals near its terminals to prevent coupling - verified in Vishay's application note AN8001 for the P6SMB Series.
