Product details
Overview
P4SMA56CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 56 V breakdown voltage (VBR min/max = 53.2–58.8 V at 1 mA), 400 W peak pulse power (10/1000 µs), and clamps to ≤77.0 V at 5.2 A peak pulse current - used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P4SMA56CAHE3/61 datasheet, P4SMA56CAHE3/61 pinout, P4SMA56CAHE3/61 application, or P4SMA56CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMA (DO-214AC) package compatibility, and compliance with UL 497B for telecom protector classification.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at 47.8 V), while the low incremental surge resistance enables fast transient response and tight clamping under repetitive 10/1000 µs surges.
Rated for 150 °C maximum junction temperature and MSL Level 1 (260 °C reflow peak), it supports automated SMT assembly without derating. The device meets AEC-Q101 stress testing requirements and is UL Recognized (QVGQ2, E136766) for use in safety-critical protectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 53.2–58.8 V at 1 mA test current - defines precise clamping onset threshold for overvoltage events |
| Stand-off Voltage VWM | 47.8 V maximum - ensures no conduction during normal 48 V system operation |
| Clamping Voltage VC | ≤77.0 V at 5.2 A IPPM - limits downstream voltage stress during 400 W transient |
| Peak Pulse Power PPPM | 400 W (10/1000 µs waveform) - sustains high-energy lightning or ESD-induced surges |
| Package | SMA (DO-214AC) - industry-standard 2-pin SMD footprint with 5.0 mm × 5.0 mm copper pad thermal design |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
| UL Recognition | QVGQ2 / E136766 - certified for use in UL 497B-compliant telecom and data line protectors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Same VBR range (55.1–60.7 V), higher PPPM (600 W), larger SMB (DO-214AA) package | Requires PCB layout change; better suited for higher-energy industrial surges | Select when >400 W pulse handling is required and board space permits larger footprint |
| SMCJ58CA | Same VBR (55.1–60.7 V), 1500 W PPPM, SMC (DO-214AB) package | Not drop-in; used where extreme surge immunity (IEC 61000-4-5 Level 4) is mandatory | Choose only if system-level testing demands >1 kW surge rating and thermal mass supports SMC mounting |
Compared with SMBJ58CA and SMCJ58CA, P4SMA56CAHE3/61 offers optimal balance of AEC-Q101 qualification, UL recognition, and compact SMA footprint - making it preferred for space-constrained automotive and telecom designs where 400 W surge immunity suffices.

FAQ
What is the breakdown voltage tolerance for P4SMA56CAHE3/61?
The P4SMA56CAHE3/61 has a specified breakdown voltage (VBR) range of 53.2 V to 58.8 V at 1 mA test current, representing ±5% tolerance around the nominal 56 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable system-level surge margin calculations.
Is P4SMA56CAHE3/61 suitable for automotive applications?
Yes, P4SMA56CAHE3/61 is AEC-Q101 qualified (indicated by the HE3 suffix) and tested for temperature cycling, high-temperature reverse bias, and ESD per automotive stress requirements. It is widely deployed in engine control units, ADAS camera modules, and body electronics for transient protection on 12 V and 48 V networks.
Does P4SMA56CAHE3/61 have UL recognition?
Yes, P4SMA56CAHE3/61 is UL Recognized under file E136766 and classification QVGQ2 per UL 497B for protectors used on telecommunications and data lines. This certification validates its safety performance in telecom infrastructure, PoE equipment, and network interface cards.
What is the maximum clamping voltage of P4SMA56CAHE3/61 under surge conditions?
The maximum clamping voltage (VC) of P4SMA56CAHE3/61 is 77.0 V at 5.2 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 400 W transient event.
How does the bidirectional configuration of P4SMA56CAHE3/61 affect PCB layout?
The bidirectional nature of P4SMA56CAHE3/61 eliminates polarity constraints - no cathode band marking is present, and either terminal may connect to line or return. This simplifies layout, reduces assembly errors, and enables symmetric placement on differential signal pairs like RS-485 or CAN bus lines.
