Product details
Overview
P6SMB10CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage 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 signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB10CAHM3/H datasheet, P6SMB10CAHM3/H pinout, P6SMB10CAHM3/H application, or P6SMB10CAHM3/H equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) under real-world PCB layout constraints.
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 (<10 μA at VWM), while the 10/1000 μs surge rating reflects standardized lightning and inductive-switching transient immunity testing.
The device is rated for continuous operation from –65 °C to +150 °C junction temperature, with derating applied above 25 °C ambient per Fig. 2. Its MSL Level 1 moisture sensitivity and matte tin-plated leads comply with J-STD-002 solderability and JESD22-B102 whisker resistance requirements - critical for high-reliability automated assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 10.5 V min / 11.6 V max at 1 mA - Voltage at which device enters avalanche region; tight tolerance enables predictable turn-on timing. |
| VC (Clamping Voltage) | 14.5 V at 41.4 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized transient waveform; confirms suitability for IEC 61000-4-5 Level 3/4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs minimum PCB copper area needed for thermal management. |
| TJ max | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive or enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suffix HM3 denotes halogen-free RoHS-compliant AEC-Q101 version. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Matte tin-plated terminals, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking required - symmetrical structure allows either terminal to serve as input or return path during transient events. |
| Cathode | Current exit point in forward bias; common terminal in bidirectional configuration | Identical electrical role to Anode; bidirectional operation eliminates need for orientation-aware placement on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals, differential buses (e.g., RS-485), and ungrounded circuits without polarity-sensitive layout constraints. |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial and automotive applications up to Level 4 (4 kV line-to-line). |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive subsystems including body control modules, ADAS sensors, and infotainment interfaces requiring long-term field reliability. |
| MSL Level 1, 260 °C reflow compatible | Supports single-pass lead-free reflow assembly without pre-baking; reduces manufacturing complexity and cost in high-volume production. |
| Glass passivated junction | Ensures stable VBR over time and temperature, low leakage (<10 μA), and resistance to humidity-induced parameter drift in harsh environments. |
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 SMB package, 10 V VWM, but lower PPPM (400 W) and higher VC (17.0 V at 32.3 A); not AEC-Q101 qualified. | Limited to commercial-grade consumer or office equipment where automotive reliability and 600 W surge margin are not required. | Select SMAJ10CA only when cost is prioritized over surge headroom and automotive qualification is unnecessary. |
| 1.5SMC10CA | Higher-power SMC package (same VWM/VC), 1500 W PPPM, larger footprint (7.11 mm × 6.22 mm), RθJA ≈ 30 °C/W. | Suitable for high-energy industrial mains protection or primary-side AC/DC input stages where PCB space permits larger package. | Choose 1.5SMC10CA when system-level surge requirements exceed 600 W or when thermal dissipation demands lower RθJA than SMB can provide. |
Compared with SMAJ10CA and 1.5SMC10CA, P6SMB10CAHM3/H uniquely balances AEC-Q101 qualification, 600 W surge capability, and compact SMB footprint - making it optimal for space-constrained automotive and industrial edge nodes where reliability and size are co-prioritized.

FAQ
What does the "HM3" suffix indicate in P6SMB10CAHM3/H?
The "HM3" suffix in P6SMB10CAHM3/H specifies halogen-free, RoHS-compliant construction with AEC-Q101 qualification - validated for automotive applications. It also denotes compliance with JESD201 Class 2 whisker resistance and MSL Level 1 handling. This distinguishes P6SMB10CAHM3/H from commercial-grade variants like P6SMB10CA-E3 and confirms its suitability for under-hood and safety-critical subsystems.
Is P6SMB10CAHM3/H bidirectional, and how does that affect PCB layout?
Yes, P6SMB10CAHM3/H is a bidirectional TVS diode, meaning it provides symmetrical clamping in both polarities without cathode band marking. This eliminates orientation dependency during placement - either terminal may connect to signal or ground. PCB layout benefits include simplified routing, reduced risk of assembly error, and native compatibility with differential or AC-coupled interfaces such as RS-485 or Ethernet PHYs.
What is the maximum clamping voltage of P6SMB10CAHM3/H, and under what test condition is it specified?
The maximum clamping voltage of P6SMB10CAHM3/H is 14.5 V, measured at 41.4 A peak pulse current using the standardized 10/1000 μs double-exponential waveform. This value represents the worst-case voltage imposed on protected circuitry during a surge event and is guaranteed across temperature and lifetime per Vishay's characterization - critical for ensuring downstream 3.3 V or 5 V ICs remain within absolute maximum ratings.
Can P6SMB10CAHM3/H replace P6SMB10A in an existing design?
No - P6SMB10CAHM3/H is bidirectional while P6SMB10A is unidirectional, so direct replacement requires verification of circuit polarity and grounding topology. Unidirectional devices require correct cathode orientation relative to ground; substituting a bidirectional part may alter clamping behavior in DC-biased paths. Layout review and transient simulation are recommended before interchange, especially in power rail protection applications.
What thermal derating applies to P6SMB10CAHM3/H above 25 °C ambient?
P6SMB10CAHM3/H follows linear derating above 25 °C ambient: peak pulse power decreases by 0.8% per °C rise, per Figure 2 in the datasheet. At 85 °C ambient, usable PPPM drops to approximately 480 W. This must be accounted for in thermally constrained enclosures. Derating assumes mounting on 0.2" × 0.2" copper pads per JEDEC standard; insufficient copper area accelerates thermal rolloff.
