Product details
Overview
P4SMA13CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V standoff voltage (VWM), and clamps to ≤18.2 V at 22 A peak pulse current under 10/1000 µs waveform - suitable for protecting MOSFET gates, sensor interfaces, and industrial I/O lines.
For engineers reviewing the P4SMA13CA-M3/61 datasheet, P4SMA13CA-M3/61 pinout, P4SMA13CA-M3/61 application, or P4SMA13CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 400 W peak pulse power rating, low incremental surge resistance, AEC-Q101 qualification eligibility (via HM3 suffix), and halogen-free RoHS compliance.
Technical Context
The P4SMA13CA-M3/61 operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling transient suppression on AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
It delivers 400 W peak pulse power (10/1000 µs) up to 91 V, derating to 300 W above that threshold, and exhibits a low clamping ratio (VC/VBR ≈ 1.42) with 0.081 %/°C temperature coefficient of VBR. Thermal resistance is 120 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1 mA - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin below VBR |
| VC @ IPPM | ≤18.2 V at 22 A - clamped voltage during worst-case 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure |
| PPPM | 400 W - peak transient energy absorption capacity; enables protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) |
| IPPM | 22 A - maximum non-repetitive surge current supported; defines minimum series impedance required for safe operation |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive or high-ambient industrial environments |
| Package | SMA (DO-214AC) - standardized SMT footprint compatible with automated placement and reflow; 0.208" × 0.157" body size |
Pinout & Package
SMA (DO-214AC) package: surface-mount, two-terminal, bidirectional device with no polarity marking - terminals are electrically symmetric and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 400 W peak pulse power (10/1000 µs) | Supports robust immunity to lightning-induced surges and inductive switching transients per IEC 61000-4-5 |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at VWM) over temperature and lifetime |
| Halogen-free & RoHS-compliant (M3 suffix) | Fulfills environmental compliance requirements for industrial and consumer electronics without compromising surge performance |
| MSL Level 1 (260 °C peak) | Allows standard lead-free reflow assembly without moisture sensitivity limitations or baking requirements |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module I/O |

IC Role / Device Role / Timing Role: Bidirectional TVS connected across differential audio paths or from line to ground to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Low clamping voltage (≤18.2 V) prevents clipping or distortion in analog audio paths while its 0.081 %/°C VBR TC ensures stable protection across operating temperature range. |
Use Scenario: Front-end surge protection for ADSL splitter inputs and line driver circuits subjected to lightning-induced surges on telephone lines. IC Role / Device Role / Timing Role: Installed between tip/ring pair and PHY IC to shunt common-mode transients before reaching sensitive broadband analog front-end components. Use Value: Symmetrical clamping and 22 A IPPM capability enable compliance with GR-1089-CORE telecom surge standards without requiring additional filtering stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same VBR range (12.4–13.7 V) but SMB package (DO-214AA); 600 W PPPM, higher IPPM (33.5 A), larger footprint (0.236" × 0.157") | Better suited for higher-energy surges where board space allows larger package; not drop-in compatible due to different pad layout | Select when surge energy exceeds 400 W or thermal dissipation requires lower RθJA (80 °C/W typical) |
| 1.5KE13CA | Through-hole DO-201AE package; same VBR and VC, but 1500 W PPPM and 102 A IPPM; higher capacitance (~1000 pF) | Designed for primary-level AC/DC input protection; unsuitable for high-speed signal lines due to parasitic capacitance | Choose only for bulk power rail protection where SMT is not required and signal bandwidth is not critical |
Compared with SMBJ13CA and 1.5KE13CA, the P4SMA13CA-M3/61 offers optimal balance of compact SMA footprint, 400 W surge rating, and low capacitance for signal-line protection - making it preferred for space-constrained, high-density PCBs in industrial and automotive edge nodes.

FAQ
What is the breakdown voltage tolerance of P4SMA13CA-M3/61?
The P4SMA13CA-M3/61 has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1 mA test current, representing a ±4.6 % tolerance around the nominal 13 V rating. This tight VBR distribution ensures predictable clamping onset across production lots and temperature ranges, critical for reliable overvoltage protection in precision analog and digital interfaces.
Is P4SMA13CA-M3/61 suitable for automotive applications?
Yes - the P4SMA13CA-M3/61 is halogen-free and RoHS-compliant, and its base P/NHM3 variant (e.g., P4SMA13CAHM3_A/H) is AEC-Q101 qualified for automotive use. While the M3/61 suffix itself denotes halogen-free commercial grade, it shares identical electrical and thermal specs with qualified versions and is widely deployed in non-safety-critical automotive modules such as infotainment I/O and body control inputs.
What is the maximum clamping voltage of P4SMA13CA-M3/61 under surge conditions?
The P4SMA13CA-M3/61 clamps to a maximum of 18.2 V when subjected to its rated 22 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during surge events and confirms compatibility with 12 V nominal systems and 3.3 V/5 V logic interfaces when used with appropriate series impedance.
Does P4SMA13CA-M3/61 have polarity markings on the package?
No - the P4SMA13CA-M3/61 is a bidirectional TVS diode and carries no polarity marking on the SMA (DO-214AC) case. Both terminals are functionally identical, allowing installation in either orientation across a protected line pair or between line and ground. This eliminates orientation errors during automated placement and simplifies layout for differential or floating signal paths.
What is the thermal resistance of P4SMA13CA-M3/61 in standard mounting conditions?
The P4SMA13CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal copper planes; adding thermal vias or ground planes can reduce RθJA by up to 30 %, improving surge duty cycle capability in high-repetition applications.
