Product details
Overview
P6SMB130CAHM3_B/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 130 V standoff voltage (VWM), 179 V maximum clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB130CAHM3_B/H datasheet, P6SMB130CAHM3_B/H pinout, P6SMB130CAHM3_B/H application, or P6SMB130CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, 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 lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports consistent clamping under repetitive transient events.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard PCB pads. Its fast response time (<1.0 ns) and compliance with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) make it suitable for robust front-end surge suppression in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1.0 mA test current - Ensures reliable turn-on within specified tolerance band during overvoltage events. |
| VC (Clamping Voltage) | 179 V at 3.4 A IPPM - Limits peak voltage seen by protected circuitry during 10/1000 μs surge, critical for downstream component survival. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients (e.g., ISO 7637-2 pulse 1/2a/5a) without failure when mounted per recommended pad layout. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimizes standby power loss and avoids false triggering in low-power sensor or battery-backed circuits. |
| TJ max. | 150 °C - Enables operation in under-hood automotive or industrial enclosures without derating at full power. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow). Cathode/anode terminals are unmarked for bidirectional configuration; polarity is non-applicable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Connects to reference plane (e.g., GND or signal common); forms symmetrical clamping path with cathode terminal. |
| Cathode | Transient return path (bidirectional) | Electrically identical to anode in CA devices; enables clamping above and below reference voltage without polarity constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or floating power rails without external polarity management. |
| 600 W peak pulse rating (10/1000 μs) | Withstands high-energy surges such as load dump or inductive switching spikes in 12 V/24 V automotive systems. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low-profile SMB package | 0.220" × 0.130" footprint supports high-density PCB layouts and compatibility with standard SMT pick-and-place equipment. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profiles without baking, reducing manufacturing overhead and handling risk. |
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 |
|---|---|---|---|
| SMAJ130CA | Same VWM (111 V) and VC (179 V), but lower PPPM (400 W) and no AEC-Q101 qualification. | Restricted to commercial-grade industrial or consumer use; not validated for automotive temperature cycling or humidity testing. | Select when cost sensitivity outweighs automotive qualification requirements and surge energy remains ≤400 W. |
| SMCJ130CA | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs, AEC-Q101 available (HM3 variant). | Requires larger PCB area and higher mounting thermal mass; suited for higher-energy threats like load dump in 24 V systems. | Choose when system-level testing reveals insufficient margin with 600 W rating or when legacy SMC footprint is retained. |
Compared with SMAJ130CA and SMCJ130CA, P6SMB130CAHM3_B/H delivers optimal balance of automotive qualification, compact SMB footprint, and 600 W surge capacity - making it ideal for space-constrained ECU modules where AEC-Q101 compliance and manufacturability are mandatory.

FAQ
What does the "CA" suffix indicate in P6SMB130CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning P6SMB130CAHM3_B/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses, or floating references without requiring polarity-aware placement. This differs from unidirectional "A" variants that require correct cathode orientation.
Is P6SMB130CAHM3_B/H suitable for automotive applications?
Yes - P6SMB130CAHM3_B/H carries the HM3 suffix, confirming halogen-free, RoHS-compliant construction and full AEC-Q101 qualification. It has passed rigorous automotive stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, making it approved for under-hood and chassis-mounted ECU designs.
What is the maximum clamping voltage of P6SMB130CAHM3_B/H and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB130CAHM3_B/H is 179 V, measured at a peak pulse current (IPPM) of 3.4 A using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events.
How does the SMB (DO-214AA) package of P6SMB130CAHM3_B/H compare to SMA or SMC packages?
P6SMB130CAHM3_B/H uses the SMB package - smaller than SMC (DO-214AB) and slightly larger than SMA (DO-214AC) - offering 600 W power handling in a 0.220" × 0.130" footprint. Its thermal resistance (RθJA = 100 °C/W) is optimized for standard 0.2" × 0.2" copper pads, balancing density, power, and manufacturability better than SMA for this power class.
Does P6SMB130CAHM3_B/H require special PCB layout considerations?
Yes - Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Narrow traces or insufficient copper reduce heat dissipation and cause premature failure; thermal vias to inner ground planes are recommended for sustained surge duty cycles.
