Product details
Overview
P6SMB16CAHM3/H 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 or power 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 - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial electronics.
For engineers reviewing the P6SMB16CAHM3/H datasheet, P6SMB16CAHM3/H pinout, P6SMB16CAHM3/H application, or P6SMB16CAHM3/H equivalent, this device is selected for bidirectional surge protection where low clamping voltage, AEC-Q101 qualification, halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity are required in space-constrained PCB layouts.
Technical Context
The P6SMB16CAHM3/H operates as a symmetrical avalanche diode, conducting equally in both directions above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 μs transients at 0.01% duty cycle.
Thermally, it supports operation from −65 °C to +150 °C junction temperature, with RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), and is rated for 5.0 W steady-state power dissipation at TA = 50 °C on infinite heatsink - optimized for surface-mount placement without additional thermal vias in standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping onset |
| VBR (Breakdown) | 15.2–16.8 V at IT = 1 mA - precise avalanche initiation range ensuring predictable turn-on during surges |
| VC (Clamping) | 22.5 V at IPPM = 26.7 A - limits transient voltage seen by downstream circuitry to protect 15–20 V-rated components |
| PPPM | 600 W (10/1000 μs) - sustains high-energy ESD or lightning-induced surges without failure under defined waveform |
| IPPM | 26.7 A - peak surge current capability directly tied to VC, defining protection level for given line impedance |
| TJ max. | +150 °C - enables use in under-hood automotive environments and high-ambient industrial settings |
| Package | SMB (DO-214AA) - 3.94 mm × 2.20 mm footprint, compatible with automated SMT assembly and meets UL 94 V-0 flammability |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking - terminals are symmetrical anode/cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional surge conduction path | Either terminal serves as input/output; no polarity dependency - simplifies layout and eliminates orientation errors |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for engine control and ADAS modules |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets JESD201 Class 2 whisker resistance and environmental regulations without compromising solderability or long-term stability |
| MSL Level 1 (260 °C peak) | Zero floor life limitation - can be mounted immediately after unpacking without baking, reducing production overhead |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) when properly laid out - reduces need for cascaded protection stages |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs - critical for safeguarding 16 V logic interfaces and CAN transceivers |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode 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; SMA package (larger footprint, higher RθJA) | Less robust for repeated surge events in automotive environments; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary |
| 1.5KE16CA | Higher PPPM = 1500 W, but axial DO-201 package - incompatible with SMT assembly and unsuitable for high-density boards | Requires through-hole mounting and manual rework; lacks MSL Level 1 rating and halogen-free compliance | Choose only for legacy through-hole designs where board real estate and automated assembly are not constraints |
Compared with SMAJ16CA and 1.5KE16CA, the P6SMB16CAHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, SMB footprint, and full 600 W surge rating - making it the optimal choice for new automotive and industrial SMT designs requiring zero-layout compromise and regulatory compliance.

FAQ
What does the "HM3" suffix indicate in P6SMB16CAHM3/H?
The HM3 suffix in P6SMB16CAHM3/H denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and AEC-Q101 qualification. It confirms the device meets automotive reliability standards and environmental regulations without compromising solderability or thermal performance - critical for P6SMB16CAHM3/H deployment in under-hood modules and safety-critical subsystems.
Is P6SMB16CAHM3/H unidirectional or bidirectional?
P6SMB16CAHM3/H is a bidirectional TVS diode, as indicated by the "CA" suffix. It provides symmetrical clamping in both polarities - essential for protecting AC-coupled lines, differential buses like RS-485, or floating power domains where voltage reversals may occur. This distinguishes P6SMB16CAHM3/H from unidirectional variants (e.g., P6SMB16AHM3/H) that conduct only in reverse bias.
What is the maximum clamping voltage of P6SMB16CAHM3/H and at what current?
The maximum clamping voltage of P6SMB16CAHM3/H is 22.5 V, measured at a peak pulse current (IPPM) of 26.7 A under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events - ensuring compatibility with 24 V-rated components and enabling reliable protection of sensitive analog and digital ICs downstream of P6SMB16CAHM3/H.
Does P6SMB16CAHM3/H require special PCB layout considerations?
Yes - P6SMB16CAHM3/H requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal performance. Short, direct traces to ground or protected node minimize inductance, and avoiding thermal relief on pads maintains low RθJA. These layout rules are essential to realize the full surge capability specified for P6SMB16CAHM3/H and prevent premature failure under stress.
How does P6SMB16CAHM3/H differ from commercial-grade P6SMB16CA-E3/52?
P6SMB16CAHM3/H differs from P6SMB16CA-E3/52 in three key ways: it is halogen-free (HM3 vs. E3), AEC-Q101 qualified (enabling automotive use), and supplied in 7" tape-and-reel (H) versus 7" commercial reel (52). The core electrical specs (VWM, VBR, VC) are identical, but P6SMB16CAHM3/H adds automotive reliability validation and stricter material compliance - making it the designated variant for P6SMB16CAHM3/H deployment in Tier 1 supply chains.
