Product details
Overview
P6SMB16AHM3/H 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), 16.8 V maximum breakdown voltage (VBR at 1.0 mA), 22.5 V maximum clamping voltage (VC) at 26.7 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 industrial and automotive electronics.
For engineers reviewing the P6SMB16AHM3/H datasheet, P6SMB16AHM3/H pinout, P6SMB16AHM3/H application, or P6SMB16AHM3/H equivalent, this device is selected for robust ESD and surge protection where low clamping voltage, fast response time, AEC-Q101 qualification, halogen-free RoHS compliance, and stable thermal performance up to 150 °C junction temperature are required.
Technical Context
The P6SMB16AHM3/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable clamping behavior under repetitive 10/1000 µs surges at 0.01% duty cycle.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation on standard 0.2" × 0.2" copper pads without heatsinking. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification per revision B for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe working margin below clamping threshold. |
| VBR (Breakdown) | 15.2–16.8 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 22.5 V at 26.7 A - Peak voltage seen by protected circuit during 600 W transient; critical for downstream component voltage tolerance. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| IPPM | 26.7 A - Peak pulse current capability; determines minimum series impedance needed to limit energy into protected node. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 2.2 mm height and 3.94 mm length; compatible with automated pick-and-place and reflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5B | Same VWM (13.6 V), identical SMB package, but rated for 400 W PPPM and not AEC-Q101 qualified. | Limited to commercial-grade industrial and consumer applications; unsuitable for automotive under-hood use. | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary. |
| 1.5SMC16A | Same electrical specs (VWM, VBR, VC), but in larger SMC (DO-214AB) package with higher thermal mass and RθJA = 60 °C/W. | Better sustained power dissipation; suited for high-duty-cycle surge environments where SMB thermal limits may be exceeded. | Choose when board space allows larger footprint and long-duration transient energy must be absorbed without thermal runaway. |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, the P6SMB16AHM3/H uniquely combines AEC-Q101 qualification, 600 W surge rating, and SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability and high transient immunity without layout redesign.

FAQ
What is the clamping voltage of the P6SMB16AHM3/H at its rated peak pulse current?
The P6SMB16AHM3/H 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 under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB16AHM3/H maintains this clamping performance across its qualified operating temperature range.
Is the P6SMB16AHM3/H suitable for automotive applications?
Yes, the P6SMB16AHM3/H is AEC-Q101 qualified (suffix HM3_B), confirming its suitability for automotive applications including engine control, body electronics, and ADAS sensor protection. It meets stringent requirements for temperature cycling, humidity resistance, mechanical shock, and long-term reliability under vibration and thermal stress - all verified per the AEC-Q101 stress test standard.
What does the "HM3" suffix indicate in P6SMB16AHM3/H?
The "HM3" suffix in P6SMB16AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification (revision B). It distinguishes this variant from commercial-grade versions (e.g., "M3") and confirms compliance with automotive material content and reliability standards. The "H" denotes 7-inch tape-and-reel packaging with 750 units per reel.
How does the P6SMB16AHM3/H compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16AHM3/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V rail to ground), offering lower leakage (<1.0 µA at VWM) and tighter VBR tolerance. In contrast, P6SMB16CA is bidirectional and suited for AC or floating signal lines. They are not interchangeable without circuit-level validation due to polarity and leakage differences.
What is the thermal resistance of the P6SMB16AHM3/H, and how does it affect PCB layout?
The P6SMB16AHM3/H 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 recommendation; reducing pad area increases thermal impedance and risks exceeding the +150 °C TJ max. specification.
