Product details
Overview
P6SMB16AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on power and signal lines. It features a 16 V standoff voltage (VWM), 22.5 V maximum clamping voltage 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 signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB16AHM3_B/H datasheet, P6SMB16AHM3_B/H pinout, P6SMB16AHM3_B/H application, or P6SMB16AHM3_B/H equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package, unidirectional polarity with cathode band marking, and compliance with J-STD-020 MSL level 1 at 260 °C peak reflow temperature.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown when reverse voltage exceeds its breakdown threshold (VBR = 15.2–16.8 V at 1 mA), limiting transient energy to protected downstream circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of ESD and inductive switching spikes without affecting normal DC operation.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2 in the datasheet. Thermal resistance from junction to ambient is 100 °C/W, and junction-to-lead is 20 °C/W - critical for layout decisions involving copper pad area (0.2" × 0.2") and thermal relief design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 26.7 A - Peak voltage seen by protected circuit under 600 W transient; determines minimum IC withstand rating. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; defines transient energy absorption capacity. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | 150 °C - Maximum junction temperature; sets upper limit for thermal design and reliability modeling. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 2.2 mm height and 3.94 mm length; compatible with automated pick-and-place. |
Pinout & Package

FAQ
What is the clamping voltage of the P6SMB16AHM3_B/H under maximum rated surge current?
The P6SMB16AHM3_B/H has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 26.7 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB16AHM3_B/H maintains this clamping performance across its qualified operating temperature range.
Is the P6SMB16AHM3_B/H suitable for automotive applications?
Yes, the P6SMB16AHM3_B/H is AEC-Q101 qualified (indicated by the "HM3_B" suffix), meaning it has passed stress tests for temperature cycling, high-temperature reverse bias, and ESD required for automotive electronics. It is explicitly intended for use in engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical. The P6SMB16AHM3_B/H meets these requirements without derating at 125 °C ambient.
What does the "_B/H" suffix in P6SMB16AHM3_B/H signify?
The "_B" denotes AEC-Q101 qualification for the P6SMB16A voltage grade, while "/H" specifies packaging in 7-inch plastic tape and reel with 750 units per reel. This ordering code aligns with Vishay's documented format in Section 3 of datasheet 88370 and confirms halogen-free, RoHS-compliant construction (HM3 prefix) plus automotive qualification (B suffix). The P6SMB16AHM3_B/H is not a sample or evaluation variant - it is a full-production, traceable commercial part.
How does the P6SMB16AHM3_B/H compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16AHM3_B/H is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., +12 V rails), offering lower leakage (<1.0 μA) and tighter VBR tolerance than its bidirectional counterpart P6SMB16CA. The P6SMB16CA supports AC-coupled or floating lines but exhibits higher ID (up to 5.0 μA) and slightly higher VC (23.0 V). Selection depends on circuit topology - the P6SMB16AHM3_B/H is optimal when ground-referenced clamping suffices.
What PCB layout considerations apply to the P6SMB16AHM3_B/H?
Per Vishay datasheet 88370, the P6SMB16AHM3_B/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Trace inductance must be minimized - keep connections short and wide, especially the cathode-to-ground path. Avoid thermal reliefs on pads; use solid copper for optimal heat dissipation. The P6SMB16AHM3_B/H thermal resistance (RθJA = 100 °C/W) assumes this layout, and deviation reduces surge capability.
