Product details
Overview
P4SMA13CA-M3/5A 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 and power lines. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V maximum standoff voltage (VWM), and 18.2 V clamping voltage (VC) at 22 A peak pulse current - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA13CA-M3/5A datasheet, P4SMA13CA-M3/5A pinout, P4SMA13CA-M3/5A application, or P4SMA13CA-M3/5A equivalent, key selection criteria include bidirectional transient suppression capability, 400 W peak pulse power (10/1000 µs), low clamping ratio (VC/VBR ≈ 1.43), AEC-Q101 qualification eligibility (M3 suffix), and halogen-free RoHS compliance.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM, and VC specifications in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive surge conditions.
The device delivers 400 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating to 300 W above 91 V and further with ambient temperature per Fig. 2. Thermal resistance is RθJA = 120 °C/W (typ.) and RθJL = 30 °C/W (typ.), supporting reliable operation up to TJ = +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1 mA - defines precise voltage threshold where avalanche conduction begins in either polarity |
| VWM | 11.1 V max - maximum continuous working voltage before leakage exceeds 1 µA; sets safe operating margin below VBR |
| VC @ IPPM | 18.2 V at 22 A - clamped voltage during 10/1000 µs surge; determines protected circuit's peak stress level |
| PPPM | 400 W (≤91 V), 300 W (>91 V) - peak transient energy absorption capacity without failure |
| IPPM | 22 A - maximum non-repetitive surge current the device sustains under standardized 10/1000 µs waveform |
| TJ range | −65 °C to +150 °C - operational junction temperature window enabling use in under-hood automotive and industrial environments |
| Package | SMA (DO-214AC) - surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal design, MSL Level 1, 260 °C reflow compatible |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case with matte tin-plated leads, polarity-unmarked for bidirectional operation; terminals are symmetrical and non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 (12.4–13.7 V) and VC (18.2 V), but SMB package (DO-214AA) - 25 % larger footprint, higher RθJA (100 °C/W) | Preferred where board space allows larger pads and higher thermal mass is needed for sustained surge duty | Select when higher thermal dissipation margin is required and PCB layout accommodates 4.5 mm × 3.9 mm outline |
| 1.5KE13CA | Through-hole TO-204AA (DO-41); same electrical specs but 1500 W peak power rating and slower response due to lead inductance | Suitable for legacy through-hole designs or high-energy surge zones where PCB real estate is not constrained | Choose only for retrofit or cost-sensitive non-automated assembly; avoid in high-speed or space-constrained SMT designs |
Compared with P4SMA13CA-M3/5A, SMBJ13CA offers better thermal performance in larger layouts but increases board area, while 1.5KE13CA provides higher energy handling at the cost of SMT compatibility and speed - making P4SMA13CA-M3/5A optimal for modern compact, high-reliability SMT systems.

FAQ
What does the "CA" suffix indicate in P4SMA13CA-M3/5A?
The "CA" suffix in P4SMA13CA-M3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both polarities, with identical breakdown, standoff, and clamping characteristics regardless of voltage polarity applied. This eliminates orientation sensitivity during placement and simplifies PCB design for AC-coupled or differential signal paths.
Is P4SMA13CA-M3/5A AEC-Q101 qualified?
P4SMA13CA-M3/5A carries the M3 suffix, indicating halogen-free and RoHS-compliant construction. While the base P4SMA13CA is AEC-Q101 qualified in HE3/HM3 variants (e.g., P4SMA13CAHM3_A), the M3/5A variant itself is not explicitly certified - users requiring automotive qualification should select P4SMA13CAHM3_A/I or confirm qualification status via Vishay's official documentation for the exact ordering code.
What is the maximum clamping voltage of P4SMA13CA-M3/5A under surge conditions?
The maximum clamping voltage (VC) of P4SMA13CA-M3/5A is 18.2 V at 22 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is measured across the device terminals with specified mounting conditions (0.2" × 0.2" copper pads).
How does the M3 suffix differ from E3 in P4SMA13CA-M3/5A?
The M3 suffix in P4SMA13CA-M3/5A indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance, whereas E3 denotes standard RoHS compliance without halogen-free assurance. Both meet UL 94 V-0 flammability and J-STD-020 MSL Level 1, but M3 adds environmental compliance for stricter regional regulations like China RoHS II.
Can P4SMA13CA-M3/5A be used in place of unidirectional P4SMA13A-M3/5A?
No - P4SMA13CA-M3/5A is bidirectional and lacks polarity marking, while P4SMA13A-M3/5A is unidirectional with cathode band identification. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating references, whereas unidirectional types are required for DC-biased rails where reverse leakage must be minimized below 1 µA at VWM.
