Product details
Overview
P6SMB16AHE3_A/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 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the P6SMB16AHE3_A/I datasheet, P6SMB16AHE3_A/I pinout, P6SMB16AHE3_A/I application, or P6SMB16AHE3_A/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 assembly on standard PCB pad layouts.
Technical Context
The P6SMB16AHE3_A/I operates as a silicon avalanche diode that enters breakdown when reverse voltage exceeds its VBR range (15.2–16.8 V), limiting transient overvoltage to ≤22.5 V at 26.7 A. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling protection against ESD, inductive switching spikes, and lightning-induced surges.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C. The device is rated for 100 A non-repetitive forward surge current (IFSM) and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, confirming suitability for high-reliability automotive electronics per AEC-Q101.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp spikes above 13.6 V.

IC Role / Device Role / Timing Role: Unidirectional TVS on differential pair supply rail to suppress common-mode transients. Use Value: 22.5 V clamping ensures compliance with GR-1089-CORE Level 3 (1.5 kV/42 Ω) without sacrificing bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5B | Same VWM (13.6 V), identical SMB package, but lower PPPM (400 W) and higher VC (25.0 V) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification or 600 W surge margin |
| 1.5SMC16A | Same VWM/VBR/VC specs, but SMC (DO-214AB) package - 2.5 mm wider, incompatible footprint | Requires PCB layout change; higher thermal mass but same electrical performance | Choose only if existing design uses SMC pads or requires higher thermal dissipation margin |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, the P6SMB16AHE3_A/I delivers certified automotive reliability, superior 600 W surge handling, and drop-in compatibility with standard SMB land patterns - making it optimal for new automotive and industrial designs where qualification and footprint reuse are critical.

FAQ
What is the clamping voltage of P6SMB16AHE3_A/I at its rated peak pulse current?
The P6SMB16AHE3_A/I has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 26.7 A using the standard 10/1000 μs waveform. This value is measured under defined test conditions per JEDEC standards and ensures predictable overvoltage limiting for protected circuits during surge events.
Is P6SMB16AHE3_A/I suitable for automotive applications?
Yes, P6SMB16AHE3_A/I is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliance and automotive-grade reliability. It supports operating temperatures from –65 °C to +150 °C and passes stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD - making it appropriate for engine control units, body electronics, and ADAS power domains.
What does the "_A/I" suffix mean in P6SMB16AHE3_A/I?
In P6SMB16AHE3_A/I, "A" denotes unidirectional polarity, "HE3" indicates RoHS-compliant and AEC-Q101-qualified construction, and "I" specifies 3200-unit tape-and-reel packaging on 13-inch diameter reels - a standard delivery format for high-volume SMT production lines requiring extended reel length and automated feeder compatibility.
How does P6SMB16AHE3_A/I compare to bidirectional TVS diodes like P6SMB16CA?
P6SMB16AHE3_A/I is unidirectional and intended for DC power line protection where polarity is fixed, offering tighter leakage control (<1.0 μA) and slightly lower clamping voltage than its bidirectional counterpart P6SMB16CA. The latter supports AC or floating signal lines but exhibits symmetric clamping in both directions and higher ID at VWM - so P6SMB16AHE3_A/I is preferred for 12 V/24 V automotive rails with defined ground reference.
What is the thermal resistance of P6SMB16AHE3_A/I and how does it affect PCB layout?
P6SMB16AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation under repetitive surges, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay's recommended land pattern - insufficient copper area will cause excessive junction temperature rise and premature failure.
