Product details
Overview
P6SMB10CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 41.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB10CAHM3_A/H datasheet, P6SMB10CAHM3_A/H pinout, P6SMB10CAHM3_A/H application, or P6SMB10CAHM3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), low incremental surge resistance, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMB package supports automated placement and meets UL 94 V-0 flammability rating.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. With 1.0 μA max reverse leakage at VWM, it minimizes standby power loss in battery-sensitive applications, and its 20 °C/W junction-to-lead thermal resistance supports localized heat dissipation under transient stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 10.5 V min / 11.6 V max at 1 mA - Ensures tight voltage tolerance for predictable clamping onset across production lots. |
| VC (Clamping) | 14.5 V max at 41.4 A - Limits downstream voltage during 600 W transient, protecting 12 V logic and analog circuitry. |
| IPPM | 41.4 A - Peak pulse current handling with 10/1000 μs waveform; determines survivability against IEC 61000-4-5 surges. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires minimum 5.0 mm × 5.0 mm copper pads for rated power dissipation. |
| TJ max | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | SMB (DO-214AA) - Low-profile SMD outline with 2.20 mm height; compatible with standard reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; both ends function identically in reverse-biased conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as input/output for clamping; no DC polarity dependency - suitable for AC lines and differential buses. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports use in ADAS sensors and body control modules. |
| Halogen-free & RoHS-compliant (HM3) | Meets JESD201 Class 2 whisker resistance and environmental compliance mandates for global OEM supply chains. |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients such as load dump and inductive switching without degradation over rated lifetime. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V and 5 V logic interfacing with 12 V systems. |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow assembly without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and VC (14.5 V), but lower PPPM (400 W) and higher RθJA (140 °C/W); SMA package (smaller footprint, lower thermal mass). | Limited to lower-energy transients; unsuitable for automotive load dump or industrial 24 V I/O where 600 W rating is required. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD only. |
| 1.5KE10CA | Higher power (1500 W), axial-leaded DO-201 package; VC = 17.0 V at 87.5 A - looser clamping ratio and incompatible SMT assembly. | Requires through-hole mounting and larger PCB area; not AEC-Q101 qualified or MSL-1 compliant. | Choose only for prototyping or legacy through-hole designs where rework tolerance outweighs production automation needs. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHM3_A/H delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, halogen-free compliance, and SMB SMT compatibility - making it the preferred choice for volume automotive and industrial designs requiring zero-layout change upgrades from earlier P6SMB variants.

FAQ
What does the "CA" suffix indicate in P6SMB10CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration: P6SMB10CAHM3_A/H provides symmetrical clamping in both polarities, making it suitable for AC signal lines, differential buses like CAN or RS-485, and any application where voltage transients may occur with either polarity. This differs from unidirectional "A" variants that require correct cathode orientation.
Is P6SMB10CAHM3_A/H qualified for automotive applications?
Yes, P6SMB10CAHM3_A/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix and Vishay documentation. It undergoes stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D, supporting deployment in engine control units, ADAS sensors, and body electronics where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P6SMB10CAHM3_A/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB10CAHM3_A/H is 14.5 V, measured at a peak pulse current (IPPM) of 41.4 A using the standardized 10/1000 μs double-exponential waveform. This value ensures protected circuits remain within safe operating limits during high-energy transients.
How does the HM3 suffix affect the material composition and compliance of P6SMB10CAHM3_A/H?
The HM3 suffix indicates P6SMB10CAHM3_A/H is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 for whisker resistance. It uses matte tin-plated leads and molding compound meeting UL 94 V-0, satisfying strict environmental and reliability requirements for automotive Tier 1 suppliers and industrial equipment manufacturers.
Can P6SMB10CAHM3_A/H replace P6SMB10A in an existing design?
No - P6SMB10CAHM3_A/H is bidirectional, while P6SMB10A is unidirectional. Substituting them requires verifying circuit polarity, layout symmetry, and clamping behavior. The CA version lacks cathode marking and conducts equally in both directions, so it must be validated in context of the specific signal path and grounding scheme used in the original P6SMB10A implementation.
