Product details
Overview
P6SMB16AHM3/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, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6SMB16AHM3/I datasheet, P6SMB16AHM3/I pinout, P6SMB16AHM3/I application, or P6SMB16AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 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 unidirectional clamping device: reverse-biased during normal operation, it remains high-impedance until transient voltage exceeds VBR, then rapidly switches to low-impedance conduction to limit voltage across protected circuitry. Its glass-passivated junction ensures stable leakage and robust surge handling under repetitive 0.01% duty cycle conditions.
The P6SMB16AHM3/I is rated for 600 W peak pulse power per 10/1000 μs waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse operating voltage before significant leakage begins; defines safe DC/AC working range. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Voltage at which device transitions into avalanche conduction; tight tolerance enables precise overvoltage threshold setting. |
| VC (Clamping) | 22.5 V at 26.7 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines worst-case stress on downstream ICs. |
| PPPM | 600 W - Peak transient energy absorption capability; sufficient for IEC 61000-4-5 Level 3 (1 kV surge) protection on 24 V systems. |
| IPPM | 26.7 A - Peak pulse current supported at VC; correlates directly with system-level surge current requirements. |
| TJ max | +150 °C - Maximum junction temperature; enables reliable operation in under-hood automotive or high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with JEDEC-standard pick-and-place and reflow profiles. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side (e.g., ground or return path); defines polarity-sensitive placement in unidirectional configuration. |
| Cathode | Avalanche conduction terminal / Clamping node | Connected to protected line (e.g., 12 V rail or sensor input); carries full transient current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS sensors, and body electronics. |

| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without moisture sensitivity concerns - eliminates baking step in high-volume SMT production. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

| Telecom Power Rail Protection | Consumer Device USB Port Protection |
Use Scenario: Secondary overvoltage protection on +12 V or +24 V telecom power distribution boards subject to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Fast-response TVS placed downstream of primary DC-DC converter to clamp residual transients that bypass upstream filters. Use Value: Achieves sub-nanosecond response time and 600 W dissipation, limiting voltage overshoot to safe levels for PoE controller ICs and Ethernet PHYs. |
Use Scenario: Input-side transient suppression on USB VBUS lines in portable audio devices and smart home hubs where ESD and hot-plug surges occur frequently. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and ground to suppress ±15 kV contact ESD (IEC 61000-4-2) and 10/1000 μs surges from faulty chargers. Use Value: Maintains 13.6 V stand-off to avoid interference with 5 V USB signaling while clamping to 22.5 V - preserving USB 2.0 eye diagram integrity. |
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/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W); not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; unsuitable for automotive due to lack of stress qualification. | Select when board space is constrained and automotive qualification is unnecessary; verify thermal margin with reduced pad area. |
| 1.5SMC16A | Same electrical specs but SMC (DO-214AB) package - larger footprint, lower RθJA (85 °C/W), higher IFSM (200 A). | Better thermal performance for high-repetition surge environments; requires larger PCB real estate and different stencil design. | Prefer for industrial power supplies or motor drives needing enhanced surge endurance and thermal headroom over compactness. |
Compared with SMAJ16A-E3/5B and 1.5SMC16A, the P6SMB16AHM3/I uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB footprint - making it the optimal choice for space-constrained automotive modules requiring certified reliability without thermal derating penalties.

FAQ
What is the clamping voltage of P6SMB16AHM3/I at its rated peak pulse current?
The P6SMB16AHM3/I has a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test method and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB16AHM3/I maintains this clamping performance across its qualified operating temperature range of -65 °C to +150 °C.
Is P6SMB16AHM3/I suitable for automotive applications?
Yes, the P6SMB16AHM3/I is AEC-Q101 qualified (denoted by the HM3 suffix), meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness required for automotive electronics. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support use in engine control units, ADAS sensors, and body control modules where reliability under thermal and mechanical stress is mandatory. The P6SMB16AHM3/I is explicitly designated for automotive-grade deployment.
What does the "HM3" suffix indicate in P6SMB16AHM3/I?
The "HM3" suffix in P6SMB16AHM3/I specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., "E3" or "M3") and confirms compliance with automotive reliability standards, material restrictions, and assembly requirements including lead-free reflow compatibility up to 260 °C. The "I" denotes 13-inch tape-and-reel packaging (3200 units per reel), optimized for high-volume SMT production. The P6SMB16AHM3/I thus delivers certified automotive performance in standardized surface-mount form.
How does P6SMB16AHM3/I compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16AHM3/I is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., VCC-to-ground protection), offering lower leakage and tighter VBR tolerance than bidirectional equivalents. In contrast, P6SMB16CA provides symmetrical clamping for AC or floating signal lines but exhibits higher reverse leakage and broader VBR spread. The P6SMB16AHM3/I's cathode-band marking and single-polarity operation simplify layout verification and reduce risk of misplacement in polarity-sensitive designs.
What is the thermal resistance of P6SMB16AHM3/I, and how does it affect PCB layout?
The P6SMB16AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per terminal. To maintain reliability under repetitive surge conditions, PCB layout must replicate this minimum pad area - undersized traces or insufficient copper will elevate junction temperature beyond the 150 °C maximum, risking parametric shift or failure. The P6SMB16AHM3/I datasheet specifies exact mounting pad dimensions to ensure validated thermal performance.
