Product details
Overview
P6SMB16CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 16 V standoff voltage (VWM), 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB16CAHM3_B/I datasheet, P6SMB16CAHM3_B/I pinout, P6SMB16CAHM3_B/I application, or P6SMB16CAHM3_B/I equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 13.6 V), while the low incremental surge resistance supports fast transient suppression with minimal voltage overshoot.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; thermal resistance from junction to ambient is 100 °C/W on standard PCB pad layout. It meets JESD201 Class 2 whisker resistance and is halogen-free and RoHS-compliant per HM3 suffix designation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before conduction begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 15.2–16.8 V at 1.0 mA - Verified breakdown threshold ensuring predictable clamping onset under ESD or surge events. |
| VC (Clamping) | 22.5 V at 26.7 A (10/1000 μs) - Peak voltage seen by downstream components during worst-case transient; critical for IC I/O voltage margining. |
| PPPM | 600 W - Sustained transient energy absorption capacity without failure; validated per REA-defined 10/1000 μs waveform. |
| TJ max. | 150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| MSL Level | Level 1 (JEDEC J-STD-020) - No floor life limitation; supports standard reflow profiles up to 260 °C peak. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (13.6 V) and VC (22.5 V), but lower PPPM (400 W) and smaller SMA package (DO-214AC); not AEC-Q101 qualified. | Limited to commercial-grade consumer or office equipment; unsuitable for automotive or harsh industrial environments. | Select SMAJ16CA only if board space is constrained and automotive qualification is unnecessary. |
| 1.5SMC16CA | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC; AEC-Q101 available only in HE3/HM3 variants (not B/I). | Supports higher-energy transients (e.g., ISO 7637-2 Pulse 1/2b) but requires larger PCB footprint and different tape/reel packaging. | Choose 1.5SMC16CA when surge immunity must exceed 600 W and layout allows SMC footprint. |
Compared with SMAJ16CA and 1.5SMC16CA, P6SMB16CAHM3_B/I uniquely balances 600 W surge capability, AEC-Q101 qualification, SMB footprint, and 13" tape-and-reel delivery (I-type) - making it optimal for volume automotive electronics production where reliability, size, and supply chain alignment are jointly critical.

FAQ
What is the clamping voltage of P6SMB16CAHM3_B/I at its rated peak pulse current?
The P6SMB16CAHM3_B/I has a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions per REA definition and reflects the highest voltage imposed on protected circuitry during a worst-case transient - critical for verifying compatibility with downstream IC absolute maximum ratings.
Is P6SMB16CAHM3_B/I suitable for automotive applications?
Yes, P6SMB16CAHM3_B/I is AEC-Q101 qualified (indicated by HM3_B/I suffix), tested for temperature cycling, highly accelerated life testing (HALT), and ESD per automotive reliability standards. It is widely deployed in engine control units, body electronics, and ADAS sensor modules where sustained operation at 150 °C junction temperature and immunity to load dump transients are required.
What does the "CA" suffix mean in P6SMB16CAHM3_B/I?
The "CA" suffix in P6SMB16CAHM3_B/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB16AHM3_B/I), it has no cathode band marking and functions identically regardless of applied polarity, ideal for AC lines or differential signaling.
What is the standoff voltage rating of P6SMB16CAHM3_B/I?
The standoff voltage (VWM) of P6SMB16CAHM3_B/I is 13.6 V - the maximum DC or continuous peak reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures reliable blocking during normal operation while allowing rapid transition to clamping mode when transients exceed this threshold.
How does the SMB package of P6SMB16CAHM3_B/I compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB16CAHM3_B/I offers a 30 % smaller footprint than SMC (DO-214AB) and 15 % larger pad area than SMA (DO-214AC), striking a balance between surge handling (600 W), thermal dissipation (RθJA = 100 °C/W), and SMT process compatibility. Its 0.220" × 0.130" outline supports high-density routing while maintaining sufficient copper pad area for effective transient energy dissipation.
