Product details
Overview
P6SMB130CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB130CAHE3/52 datasheet, P6SMB130CAHE3/52 pinout, P6SMB130CAHE3/52 application, or P6SMB130CAHE3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), clamping performance under standardized surge conditions, and real-world protection use cases - all critical for robust overvoltage design validation.
Technical Context
The P6SMB130CAHE3/52 operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±179 V in either polarity while maintaining ≤1.0 μA reverse leakage at 111 V (VWM). Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it meets MSL Level 1 per J-STD-020, supports reflow up to 260 °C peak, and is qualified to AEC-Q101 for automotive-grade reliability - distinguishing it from commercial-only variants like P6SMB130CA-E3/52.
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 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 179 V at IPPM = 3.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe IC stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability without failure under standardized waveform. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; requires minimum 5.0 mm × 5.0 mm copper pad per terminal for rated derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control, ADAS sensors, and infotainment interfaces. |
| Package | SMB (DO-214AA) - Low-profile, surface-mount outline compatible with automated pick-and-place and reflow. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Accepts reverse surge current during negative transients; symmetrical with cathode for bidirectional operation. |
| Cathode | Transient current entry (positive polarity) | Accepts reverse surge current during positive transients; functionally identical to anode in CA-type devices. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity concerns. |
| 600 W peak pulse power | Supports robust immunity to 10/1000 μs surges up to 3.4 A - sufficient for IEC 61000-4-5 Level 3 (1 kV line-to-ground). |
| Glass passivated junction | Ensures stable VBR over temperature and lifetime, minimizing parameter drift in harsh environments. |
| MSL Level 1 rating | Permits unlimited floor life and standard reflow profile compatibility without baking preconditioning. |

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), VC = 196 V at 3.1 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required. | Select when space-constrained layouts prioritize smaller size over peak power headroom. |
| 1.5KE130CA | Same VWM/VC ratings but through-hole DO-201 package; higher thermal mass but incompatible with SMT assembly. | Not suitable for high-volume automated production; used only in legacy or low-volume prototyping. | Choose only if existing PCB design mandates axial-leaded components or manual assembly. |
Compared with SMAJ130CA and 1.5KE130CA, the P6SMB130CAHE3/52 delivers superior 600 W surge handling in an AEC-Q101-qualified SMT package - making it the preferred choice for automotive and industrial designs requiring validated reliability, automated manufacturability, and margin against worst-case transients.

FAQ
What is the clamping voltage of P6SMB130CAHE3/52 and how is it measured?
The clamping voltage (VC) of P6SMB130CAHE3/52 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 represents the maximum voltage that appears across the device during surge conduction and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The test condition is defined in the Vishay datasheet (Document Number: 88370) and applies equally in both directions due to its bidirectional construction.
Is P6SMB130CAHE3/52 qualified for automotive applications?
Yes, P6SMB130CAHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet (Revision: 09-Jan-2024). This qualification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock - validating its suitability for under-hood and cabin electronics such as engine control modules, ADAS camera interfaces, and body control units. Commercial variants like P6SMB130CA-E3/52 lack this certification.
What does the "CA" suffix mean in P6SMB130CAHE3/52?
The "CA" suffix in P6SMB130CAHE3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" versions (e.g., P6SMB130A), the CA variant has no cathode marking and functions identically in either orientation - ideal for protecting AC-coupled signals, differential buses (CAN, RS-485), or dual-rail power domains where polarity reversal may occur.
What is the thermal resistance of P6SMB130CAHE3/52 and how does it affect layout?
The junction-to-ambient thermal resistance (RθJA) of P6SMB130CAHE3/52 is 100 °C/W, measured with 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal PCB copper; reducing pad area increases thermal impedance and degrades surge capability. For reliable 600 W pulse handling, designers must implement at least the recommended pad layout and avoid excessive trace length or isolation - otherwise, localized heating may cause premature failure during repetitive surges.
How does P6SMB130CAHE3/52 differ from P6SMB130AHE3/52?
P6SMB130CAHE3/52 is bidirectional with symmetrical clamping in both polarities and no polarity marking, whereas P6SMB130AHE3/52 is unidirectional with a cathode band and only suppresses positive transients (reverse-biased operation). Their VWM (111 V), VBR (124–137 V), and VC (179 V) ratings are identical, but the unidirectional version conducts forward current during negative excursions - potentially damaging downstream circuitry if misapplied. The CA variant eliminates this risk in AC or floating signal paths.
