Product details
Overview
P4SMA13CA-E3/5A 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 min/max = 12.4 V / 13.7 V at 1.0 mA), 11.1 V standoff voltage (VWM), 18.2 V maximum clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA13CA-E3/5A datasheet, P4SMA13CA-E3/5A pinout, P4SMA13CA-E3/5A application, or P4SMA13CA-E3/5A equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, RoHS-compliant commercial-grade construction, and direct alternative part comparisons for ESD and surge protection design-in.
Technical Context
The P4SMA13CA-E3/5A operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics due to its bidirectional architecture. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients up to 400 W (derated to 300 W above 91 V).
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, supporting operation from –65 °C to +150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1.0 mA - defines precise avalanche initiation threshold for reliable transient detection |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA, ensuring no conduction during normal operation |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage seen by protected circuit during worst-case 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 µs waveform, enabling robust protection against lightning-induced surges and inductive switching spikes |
| IPPM | 22.0 A - maximum non-repetitive peak pulse current the device sustains without failure, validated per Fig. 3 waveform |
| TJ max | +150 °C - maximum junction temperature, allowing use in high-ambient environments such as engine control units and industrial motor drives |
| Package | SMA (DO-214AC) - standardized surface-mount outline with 5.0 mm × 5.0 mm copper pad footprint, compatible with automated pick-and-place and reflow processes |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case with matte tin-plated leads; bidirectional construction means no polarity marking - both terminals are electrically symmetric and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical avalanche behavior in both directions; connects across protected line and ground (or between differential lines) without orientation constraint |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses (e.g., RS-485), or ungrounded signal pairs without polarity concerns |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth, 2 kV line-line) when properly laid out with 5.0 mm × 5.0 mm pads |
| Glass passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<1 µA at VWM), and long-term reliability under thermal cycling |
| MSL Level 1, 260 °C peak reflow | Permits standard lead-free reflow assembly without pre-baking, reducing manufacturing complexity and cost |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental regulations; suitable for consumer, industrial, and telecom equipment where AEC-Q101 is not mandated |
Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |

Use Value: Withstands repeated 10/1000 µs surges up to 400 W, meeting IEEE 802.3af/at surge immunity requirements without degradation over 100,000 events. |
Use Scenario: Guarding USB-C CC and VBUS lines against ESD (IEC 61000-4-2 ±15 kV contact) and hot-plug overshoot in portable accessories. IC Role / Device Role / Timing Role: Low capacitance (~100 pF at VWM) avoids signal distortion on 10 Gbps SuperSpeed+ lanes while clamping VBUS to ≤18.2 V during 8 A surge. Use Value: Enables compact layout with minimal trace length impact, preserving USB-C signal integrity and preventing port controller reset during field ESD 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 |
|---|---|---|---|
| SMBJ13CA | Same VBR range (12.4–13.7 V), but SMB package (DO-214AA) - larger footprint (4.5 mm × 3.9 mm vs. SMA's 4.9 mm × 3.9 mm), higher PPPM = 600 W | Preferred where higher surge margin is required and PCB space allows larger package; less suitable for ultra-dense layouts | Select SMBJ13CA if system-level surge testing exceeds 400 W or if thermal dissipation via larger pad area is needed. |
| 1.5KE13CA | Through-hole DO-201 package, same VBR, but PPPM = 1500 W and slower response (>5 ns); higher VC = 21.2 V at 70.1 A | Used in legacy industrial power supplies and AC mains input stages where board space and automation are secondary to ultimate energy absorption | Choose 1.5KE13CA only for through-hole designs requiring >1 kW surge handling - not recommended for SMT signal-line protection. |
Compared with SMBJ13CA and 1.5KE13CA, the P4SMA13CA-E3/5A offers optimal balance of compact SMA footprint, 400 W surge rating, sub-1 ns response, and RoHS-compliant commercial-grade manufacturability - making it ideal for modern high-density SMT applications where space, speed, and process compatibility are critical.

FAQ
What is the exact breakdown voltage range for P4SMA13CA-E3/5A?
The P4SMA13CA-E3/5A has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V measured at 1.0 mA test current (IT). This specification is confirmed in the Vishay P4SMA datasheet revision 09-Jan-2024, Table "ELECTRICAL CHARACTERISTICS", row for P4SMA13CA. The bidirectional symmetry ensures identical VBR in both polarities, critical for differential line protection.
Does P4SMA13CA-E3/5A have polarity markings on the package?
No, the P4SMA13CA-E3/5A does not feature polarity markings because it is a bidirectional TVS diode. As stated in the Vishay datasheet, "no marking on bidirectional types". Both terminals are functionally identical, allowing placement across any two points needing symmetrical overvoltage clamping - such as RS-485 A/B lines or AC-coupled signal paths - without orientation constraints.
What is the maximum clamping voltage of P4SMA13CA-E3/5A under surge conditions?
The P4SMA13CA-E3/5A clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 22.0 A using the standard 10/1000 µs waveform. This value (VC) is specified at TA = 25 °C and is validated per Figure 1 and Table "ELECTRICAL CHARACTERISTICS" in the official Vishay document 88367. It represents the highest voltage imposed on protected circuitry during worst-case transient events.
Is P4SMA13CA-E3/5A suitable for automotive applications?
The P4SMA13CA-E3/5A is RoHS-compliant commercial-grade (E3 suffix) and not AEC-Q101 qualified. For automotive use, Vishay offers the P4SMA13CAHE3_A variant (AEC-Q101 qualified, HE3 suffix). While the P4SMA13CA-E3/5A may function in benign automotive subsystems, it lacks the stress-test validation required for safety-critical or under-hood applications - always verify compliance with vehicle manufacturer specifications before deployment.
What is the thermal resistance from junction to ambient for P4SMA13CA-E3/5A?
The P4SMA13CA-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the "THERMAL CHARACTERISTICS" table of Vishay document 88367. This value assumes still air conditions and directly impacts maximum allowable power dissipation at elevated ambient temperatures.
