Product details
Overview
P6SMB130CA-M3/52 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 interfaces, industrial I/O modules, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB130CA-M3/52 datasheet, P6SMB130CA-M3/52 pinout, P6SMB130CA-M3/52 application, or P6SMB130CA-M3/52 equivalent, key selection criteria include bidirectional clamping capability, 179 V VC under 3.4 A surge, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification eligibility, and SMB package thermal performance (RθJA = 100 °C/W).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.
The device achieves fast response time (<1.0 ns) and low incremental surge resistance, enabling effective suppression of sub-microsecond transients. Its M3 suffix confirms halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity rating (peak reflow 260 °C).
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 - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 179 V at IPPM = 3.4 A - Peak voltage seen by protected circuit during 600 W transient; determines safe IC stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability with 10/1000 μs waveform; meets industrial surge immunity standards. |
| ID (Reverse Leakage) | ≤1.0 μA at 111 V - Minimal standby current; avoids signal distortion or battery drain in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| RθJA | 100 °C/W - Thermal resistance to ambient on standard 0.2" × 0.2" copper pads; guides PCB thermal layout design. |
Pinout & Package

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and Hall-effect sensor outputs from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point.

Use Value: Sub-1 ns response and 179 V clamping prevent latch-up in USB PD controllers during repeated ±8 kV air discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-T | Same VWM (111 V), VC = 219 V at 2.75 A; lower PPPM (600 W same), higher RθJA (120 °C/W) | Higher clamping voltage reduces protection margin for 3.3 V/5 V logic; better suited for 24 V systems | Select when higher VC tolerance is acceptable and SMB footprint must be retained without redesign. |
| 1.5KE130CA | Through-hole DO-201 package; same VWM/VC specs but larger size, higher IFSM (100 A), lower RθJA (60 °C/W) | Not suitable for dense SMT layouts; preferred for high-reliability power supply primary-side surge protection | Choose for legacy through-hole designs or where thermal mass improves sustained surge handling beyond 600 W single-event limit. |
Compared with SMBJ130CA-T, P6SMB130CA-M3/52 offers tighter clamping (179 V vs. 219 V) critical for low-voltage ICs; versus 1.5KE130CA, it enables miniaturized SMT implementation but requires careful thermal pad design due to higher RθJA.

FAQ
What does the "CA" suffix indicate in P6SMB130CA-M3/52?
The "CA" suffix in P6SMB130CA-M3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB130A), P6SMB130CA-M3/52 has no cathode band marking and functions identically whether voltage is applied positive-to-negative or negative-to-positive across its terminals, making it ideal for AC signal lines and differential buses.
Is P6SMB130CA-M3/52 qualified to AEC-Q101?
P6SMB130CA-M3/52 itself is not AEC-Q101 qualified, but it shares the same die and process as the AEC-Q101-qualified variant P6SMB130CAHM3_B/H (or _I). The M3 suffix confirms halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance-key prerequisites for automotive qualification. Customers requiring full AEC-Q101 certification should specify the HM3_B/H or HM3_B/I ordering code instead of P6SMB130CA-M3/52.
What is the maximum clamping voltage of P6SMB130CA-M3/52 under surge conditions?
The maximum clamping voltage (VC) of P6SMB130CA-M3/52 is 179 V, measured at a peak pulse current (IPPM) of 3.4 A using the standard 10/1000 μs double-exponential waveform. This value represents the highest voltage the device allows to pass through to the protected circuit during a 600 W transient event, directly defining the overvoltage stress imposed on downstream components such as microcontrollers or interface ICs.
How does the SMB package of P6SMB130CA-M3/52 affect thermal performance?
The SMB (DO-214AA) package of P6SMB130CA-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This means each watt of dissipated power raises the junction temperature by 100 °C above ambient-requiring careful PCB layout with adequate copper area to maintain TJ ≤ 150 °C during repetitive surges. Larger pads or internal planes can reduce RθJA, but the base specification assumes minimal recommended land pattern.
Can P6SMB130CA-M3/52 replace P6SMB130A in an existing design?
No-P6SMB130CA-M3/52 cannot directly replace unidirectional P6SMB130A without circuit review. While both share identical VWM (111 V), VBR (124–137 V), and VC (179 V), the CA version is bidirectional with no polarity marking, whereas the A version is unidirectional with a cathode band. Substituting P6SMB130CA-M3/52 in a unidirectional layout may cause unintended conduction during normal forward bias, risking malfunction. Verify system polarity requirements before interchange.
