Product details
Overview
P6SMB16AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB16AHE3/5B datasheet, P6SMB16AHE3/5B pinout, P6SMB16AHE3/5B application, or P6SMB16AHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly and high-reliability environments.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping protection device, conducting only when reverse voltage exceeds VBR to shunt transient energy away from downstream components. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMB package supports 600 W peak pulse power under JEDEC-standard 10/1000 μs waveform conditions.
Thermal performance is defined by RθJA = 100 °C/W (junction-to-ambient, on minimum pad layout) and RθJL = 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = 150 °C. The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing, confirming suitability for lead-free reflow processes with peak temperatures up to 260 °C.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple transients per ISO 7637-2.

IC Role / Device Role / Timing Role: Reverse-biased TVS on signal line to ground, absorbing fast transients before reaching ADC input or op-amp buffer. Use Value: Maintains signal integrity by clamping transients to 22.5 V while adding <0.5 pF capacitance - negligible impact on kHz-range sensor bandwidth. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Protection |
|
Use Scenario: Safeguarding AC-DC adapter primary-side rectifier and controller ICs from lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Mounted across bulk capacitor or bridge rectifier output to clamp overvoltage spikes before they reach PWM IC. Use Value: Absorbs 600 W pulses without degradation, enabling compliance with IEC 61000-4-5 Level 3 (2 kV line-earth) with minimal board space. |
Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFETs driven by isolated gate drivers in motor inverters. IC Role / Device Role / Timing Role: Placed between gate and source to clamp Miller-induced voltage spikes during switching transitions. Use Value: Clamps gate-source voltage to ≤22.5 V during dV/dt events, preserving 20 V gate rating margin and avoiding unintended turn-on. |
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/VBR/VC specs but rated for 400 W PPPM (vs. 600 W); SMA package (DO-214AC), smaller footprint and lower thermal mass. | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump where 600 W is required. | Select P6SMB16AHE3/5B when 600 W surge handling or AEC-Q101 qualification is mandatory; choose SMAJ16A-E3/5B only for space-constrained consumer designs with lower threat levels. |
| 1.5SMC16A | Same electrical specs and 600 W rating, but in larger SMC (DO-214AB) package; RθJA = 60 °C/W (vs. 100 °C/W), better thermal dissipation. | Requires more PCB area; preferred for high-temperature ambient environments (>85 °C) or repetitive surge conditions requiring lower junction rise. | Choose P6SMB16AHE3/5B for standard SMT automation and AEC-Q101 compliance; use 1.5SMC16A only when thermal derating headroom is insufficient with SMB layout. |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, the P6SMB16AHE3/5B uniquely balances 600 W surge capability, AEC-Q101 qualification, and SMB footprint - making it optimal for automotive and industrial applications where reliability, standardized assembly, and moderate thermal constraints coexist.

FAQ
What is the maximum clamping voltage of the P6SMB16AHE3/5B under peak pulse conditions?
The P6SMB16AHE3/5B has a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB16AHE3/5B maintains this clamping performance across its qualified operating temperature range and after repeated surge exposure when mounted per the recommended 0.2" × 0.2" copper pad layout.
Is the P6SMB16AHE3/5B qualified for automotive applications?
Yes, the P6SMB16AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet (Document Number 88370, Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and surge endurance - validating its use in automotive powertrain, body electronics, and ADAS modules. The P6SMB16AHE3/5B meets MSL Level 1 and supports lead-free reflow up to 260 °C, aligning with automotive manufacturing requirements.
What does the "5B" in P6SMB16AHE3/5B indicate?
The "5B" in P6SMB16AHE3/5B specifies the packaging configuration: 13-inch diameter plastic tape and reel, with 3200 units per reel. This differs from "52", which denotes a 7-inch reel with 750 units. The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification, while "B" in the suffix indicates the revision level per Vishay's ordering nomenclature. The P6SMB16AHE3/5B is fully compatible with standard SMT pick-and-place equipment and reflow profiles for DO-214AA packages.
How does the P6SMB16AHE3/5B compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16AHE3/5B is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-ground), offering lower leakage and tighter VBR tolerance than bidirectional variants. In contrast, P6SMB16CA provides symmetrical clamping for AC or floating signal lines but exhibits higher reverse leakage above VWM. For applications requiring AEC-Q101 qualification and DC rail protection, the P6SMB16AHE3/5B is preferred; P6SMB16CA would be selected only when bidirectional surge immunity is essential, such as in RS-485 or CAN bus termination networks.
What is the thermal resistance of the P6SMB16AHE3/5B, and how does it affect layout design?
The P6SMB16AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" copper pads per terminal, and a junction-to-lead resistance (RθJL) of 20 °C/W. These values require PCB layouts to include adequate copper area for heat spreading - especially under repetitive surge conditions - to prevent junction temperature from exceeding 150 °C. Reducing pad size or omitting thermal vias increases RθJA, directly degrading the P6SMB16AHE3/5B's surge endurance and long-term reliability.
