Product details
Overview
P6SMB15AHE3/5B 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 (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power supplies.
For engineers reviewing the P6SMB15AHE3/5B datasheet, P6SMB15AHE3/5B pinout, P6SMB15AHE3/5B application, or P6SMB15AHE3/5B equivalent, this AEC-Q101 qualified TVS offers verified unidirectional clamping performance, RoHS-compliant matte tin terminals, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive PCB assembly and surge immunity validation.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 12.8 V stand-off rating (VWM) and clamping transient energy within 1 ns response time. Its glass-passivated junction ensures stable VBR temperature coefficient (0.084 %/°C) and low incremental surge resistance.
Designed for automated SMT placement on 5.0 mm × 5.0 mm copper pads, it delivers 600 W peak pulse power with 0.01 % duty cycle, derated above 25 °C per Fig. 2, and supports 100 A non-repetitive forward surge (8.3 ms half-sine) - enabling robust protection of DC input rails and I/O interfaces without crowbar action.
Key Specifications

Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed across noisy motor control boards. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt ESD and inductive kickback from adjacent relays or solenoids. Use Value: Clamps ±15 kV contact ESD (IEC 61000-4-2) to <22 V, preserving ADC input integrity and avoiding signal corruption. |

Use Scenario: -48 V telecom power feeds entering base station cabinets with long cable runs. IC Role / Device Role / Timing Role: Unidirectional TVS on feed line to protect upstream DC-DC converters and monitoring ICs. Use Value: Withstands repeated 10/1000 µs surges up to 28.3 A while maintaining VWM = 12.8 V for stable biasing of supervision circuitry. |
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 400 W PPPM rating and SMA package (smaller thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost or board space is prioritized over automotive qualification and 600 W surge margin |
| 1.5SMC15A | Same electrical specs, but SMC (DO-214AB) package - 20 % larger footprint and higher RθJA (125 °C/W) | Lower power density; requires larger copper area for thermal management | Choose only if existing layout uses SMC footprints and no redesign is permitted |
Compared with SMAJ15A-E3/5B and 1.5SMC15A, P6SMB15AHE3/5B uniquely combines AEC-Q101 qualification, 600 W surge capacity in the compact SMB outline, and MSL Level 1 reflow compatibility - making it the optimal choice for new automotive and industrial designs requiring validated reliability and high pulse power density.

FAQ
What is the clamping voltage of P6SMB15AHE3/5B under a 600 W transient?
The P6SMB15AHE3/5B clamps to 21.2 V at its rated peak pulse current of 28.3 A, which corresponds to the 600 W (10/1000 µs) surge condition. This value is measured per Figure 1 in the Vishay datasheet 88370 and reflects actual device behavior under standardized surge testing - not a theoretical limit. The clamping voltage remains stable across temperature due to its 0.084 %/°C VBR coefficient.
Is P6SMB15AHE3/5B suitable for automotive applications?
Yes, P6SMB15AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's revision 09-Jan-2024 datasheet. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling (TCT), and unbiased highly accelerated stress testing (UHAST), making it suitable for under-hood and body-control module applications where reliability under thermal and mechanical stress is mandatory.
What does the "5B" in P6SMB15AHE3/5B indicate?
The "5B" denotes the packaging configuration: 13-inch diameter plastic tape and reel containing 3200 units. This differs from "52", which indicates a 7-inch reel with 750 units. Both use the same P6SMB15AHE3 die and SMB package; the "5B" variant is optimized for high-volume SMT production lines requiring longer reel lengths to minimize changeover frequency.
How does P6SMB15AHE3/5B differ from bidirectional variants like P6SMB15CA?
P6SMB15AHE3/5B is unidirectional, with a cathode band marking and specified parameters only for reverse-bias operation (VWM = 12.8 V, VBR = 14.3–15.8 V). In contrast, P6SMB15CA is bidirectional, offering symmetric clamping in both polarities (VWM = 12.8 V, VBR = ±14.3–15.8 V), suited for AC-coupled or floating signal lines. The HE3 suffix confirms AEC-Q101 qualification applies only to the unidirectional P6SMB15AHE3/5B, not the CA version.
What is the maximum operating temperature for P6SMB15AHE3/5B?
The P6SMB15AHE3/5B has a maximum junction temperature (TJ) of +150 °C, as specified in the "Maximum Ratings" table of Vishay document 88370. This allows continuous operation in ambient temperatures up to +125 °C when mounted on recommended 5.0 mm × 5.0 mm copper pads, given its RθJA of 100 °C/W. Derating curves in Figure 2 confirm usable power dissipation down to 50 % at 100 °C ambient.
