Product details
Overview
P6SMB16CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM), 22.5 V maximum clamping voltage (VC) at 26.7 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects signal lines and power rails in automotive sensor units, industrial I/O interfaces, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB16CAHM3_A/I datasheet, P6SMB16CAHM3_A/I pinout, P6SMB16CAHM3_A/I application, or P6SMB16CAHM3_A/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification status, 22.5 V VC under 26.7 A surge, MSL Level 1 moisture sensitivity, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR (15.2–16.8 V), VWM (13.6 V), and VC (22.5 V) specifications. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting sensitive analog inputs and high-speed digital interfaces.
Designed for automated SMT assembly, it meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 (260 °C peak reflow). The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification-verified for automotive-grade reliability in engine control modules and ADAS sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Tight 10% tolerance ensures predictable turn-on during transient events. |
| VC (Clamping) | 22.5 V at 26.7 A - Limits downstream voltage stress to protect 24 V-rated ICs and MOSFETs. |
| PPPM | 600 W (10/1000 μs) - Withstands repetitive lightning-induced surges in industrial Ethernet ports. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments without derating. |
| Package | SMB (DO-214AA) - 0.220" × 0.130" footprint; compatible with standard 0.2" × 0.2" copper pad layout per datasheet fig. 6. |
| AEC-Q101 | Qualified - Validated for automotive applications including powertrain and body electronics per HM3 suffix. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional device with no polarity marking (no cathode band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Connects to protected line; conducts surge current in either polarity relative to Anode terminal. |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode in bidirectional configuration; forms symmetrical clamping pair. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions-eliminates need for orientation-aware placement on PCB. |
| AEC-Q101 qualification | Validated for automotive use per HM3 suffix; supports deployment in engine control units without additional qualification. |
| MSL Level 1 rating | Zero floor-life limitation; can be stored indefinitely and reflowed at 260 °C peak without baking. |
| Halogen-free & RoHS | HM3 suffix guarantees compliance with EU RoHS Directive 2011/65/EU and halogen-free material requirements. |
| 600 W surge capability | Handles IEC 61000-4-5 Level 4 (4 kV) surges on 24 V industrial bus lines with margin. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN FD and LIN bus transceivers in vehicle cabin temperature sensors exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector interface to shunt transients before reaching PHY layer. Use Value: 22.5 V clamping ensures transceiver ICs (e.g., TJA1044) remain within absolute maximum ratings during 100 V/50 ms load dump events. |
Use Scenario: Safeguarding 24 V DC input channels of programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary overvoltage protection element mounted adjacent to terminal block entry point. Use Value: 600 W peak power rating sustains repeated 1 kV/500 A surges per IEC 61000-4-4 without degradation. |
| Telecom Line Card Surge Suppression | Consumer Appliance Motor Drive Protection |
Use Scenario: Front-end protection of PoE-powered Ethernet switches handling IEEE 802.3bt Class 5/6 power delivery. IC Role / Device Role / Timing Role: Secondary TVS stage after gas discharge tube (GDT), clamping residual transients to sub-25 V levels. Use Value: Low clamping voltage (22.5 V) prevents latch-up in PMICs powering 24 V auxiliary rails. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in smart washing machine control boards. IC Role / Device Role / Timing Role: Parallel-mounted across motor terminals to absorb inductive energy during PWM switching. Use Value: 150 °C max junction temperature allows uninterrupted operation during sustained 60 °C ambient cabinet conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (13.6 V), VC (24.4 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); not AEC-Q101 qualified. | Select when board space is constrained and automotive qualification is unnecessary. |
| 1.5KE16CA | Higher power (1500 W), axial-leaded DO-201 package; VWM = 13.6 V, VC = 24.4 V; no MSL or AEC-Q101 rating. | Suitable for prototyping or through-hole legacy designs; incompatible with automated SMT lines. | Choose only for manual assembly or high-surge test fixtures where reflow compatibility is irrelevant. |
Compared with SMAJ16CA and 1.5KE16CA, P6SMB16CAHM3_A/I uniquely delivers AEC-Q101 qualification, MSL Level 1 reflow robustness, and 600 W surge capacity in an SMT-optimized SMB package-making it the sole choice for production automotive and industrial SMT lines requiring zero process deviation.

FAQ
What does the "CA" suffix indicate in P6SMB16CAHM3_A/I?
The "CA" suffix denotes a bidirectional configuration: P6SMB16CAHM3_A/I provides symmetrical clamping in both forward and reverse directions, with identical breakdown (15.2–16.8 V), standoff (13.6 V), and clamping (22.5 V) characteristics. This eliminates polarity concerns during PCB layout and enables single-device protection of AC-coupled or differential signal paths-unlike unidirectional variants such as P6SMB16A.
Is P6SMB16CAHM3_A/I suitable for automotive applications?
Yes, P6SMB16CAHM3_A/I is AEC-Q101 qualified per its HM3 suffix and documented in Vishay's automotive-grade ordering matrix. It has passed stress tests including temperature cycling, humidity bias, and mechanical shock-making it approved for use in engine control units, ADAS camera modules, and body electronics where transient immunity and long-term reliability are mandatory.
What is the maximum clamping voltage of P6SMB16CAHM3_A/I and how is it measured?
The maximum clamping voltage (VC) of P6SMB16CAHM3_A/I is 22.5 V, measured at 26.7 A peak pulse current using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the highest voltage imposed on protected circuitry during worst-case surge events-and is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88370.
Does P6SMB16CAHM3_A/I require special PCB layout considerations?
Yes-Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal to achieve rated 600 W pulse power dissipation. Smaller pads increase thermal resistance and reduce surge capability. The SMB (DO-214AA) outline drawing on page 5 mandates 0.086" (2.20 mm) minimum cathode-to-anode distance and 0.220" (5.59 mm) overall length for reliable solder joint formation.
How does the HM3 suffix differ from M3 or E3 in P6SMB16CAHM3_A/I?
The HM3 suffix in P6SMB16CAHM3_A/I indicates halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification-whereas M3 is halogen-free/RoHS without automotive qualification, and E3 is RoHS-compliant commercial grade only. The "H" prefix in HM3 explicitly denotes AEC-Q101 validation, verified in Vishay's ordering information table (page 3, footnote 1).
