Product details
Overview
P4SMA62CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 53.0 V standoff voltage (VWM), clamps to ≤85.0 V at 4.7 A peak pulse current, and delivers 400 W peak pulse power (10/1000 µs waveform) - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P4SMA62CAHM3/H datasheet, P4SMA62CAHM3/H pinout, P4SMA62CAHM3/H application, or P4SMA62CAHM3/H equivalent, this device serves as an AEC-Q101-qualified, halogen-free, RoHS-compliant TVS for bidirectional transient suppression where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical design requirements.
Technical Context
The P4SMA62CAHM3/H operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±53.0 V in either polarity without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while its DO-214AC (SMA) package supports automated placement and withstands 260 °C peak reflow per J-STD-020.
It is rated for 150 °C maximum junction temperature, exhibits 0.104 %/°C temperature coefficient of VBR, and delivers 4.7 A peak pulse current (IPPM) under standardized 10/1000 µs surge conditions - with derating applied above 25 °C ambient per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise avalanche initiation threshold for bidirectional clamping |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | ≤85.0 V at 4.7 A - clamping voltage during 10/1000 µs surge, directly limiting protected circuit stress |
| PPPM | 400 W (10/1000 µs) - peak surge energy handling capacity on standard PCB pad layout |
| IPPM | 4.7 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max. | 150 °C - enables reliable operation in under-hood automotive and industrial ambient environments |
| Temp. Coeff. of VBR | 0.104 %/°C - quantifies drift of breakdown voltage with temperature, critical for precision protection |
Pinout & Package
Package: SMA (DO-214AC) - surface-mount, low-profile plastic case with matte tin-plated leads, compliant with J-STD-002 solderability and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking - symmetrical terminals enable identical function in both directions |
| Cathode | Current exit point in forward bias; common terminal in bidirectional configuration | Identical physical terminal to Anode; bidirectional operation eliminates functional distinction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher 64 V VBR range (60.8–67.2 V), same SMA package, 600 W PPPM | Clamps at higher voltage (≤103 V), better suited for 48 V systems with larger margin | Select when system VCC exceeds 53 V and higher clamping tolerance is acceptable |
| 1.5KE62CA | Through-hole DO-15 package, same 62 V rating, 1500 W PPPM, higher IPPM (24.3 A) | Requires PCB through-hole real estate and wave soldering; not suitable for SMT-only lines | Choose only for legacy through-hole designs or where higher surge energy handling is mandatory |
Compared with SMBJ64CA and 1.5KE62CA, the P4SMA62CAHM3/H offers optimal balance of AEC-Q101 qualification, halogen-free compliance, and compact SMA footprint for modern automotive and industrial SMT assemblies - delivering verified 400 W clamping performance without layout or process compromise.

FAQ
What is the breakdown voltage tolerance of the P4SMA62CAHM3/H?
The P4SMA62CAHM3/H has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at 1 mA test current, representing a ±5% tolerance around the nominal 62 V rating. This tight distribution ensures predictable clamping behavior across production lots and supports robust design margins in safety-critical applications like automotive sensor interfaces where overvoltage thresholds must remain within defined limits.
Is the P4SMA62CAHM3/H suitable for automotive applications?
Yes, the P4SMA62CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It meets stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114, making it appropriate for under-hood and cabin ECU protection where sustained 150 °C junction operation and surge immunity are required - confirmed in Vishay's official P4SMA qualification report.
What does the "CA" suffix indicate in P4SMA62CAHM3/H?
The "CA" suffix in P4SMA62CAHM3/H denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VWM, and VC characteristics regardless of voltage polarity. Unlike unidirectional variants (e.g., P4SMA62AHM3/H), it has no cathode band marking and is used where AC-coupled signals, differential buses, or polarity-agnostic protection is needed - such as in RS-485 or CAN FD interfaces.
What is the maximum clamping voltage of the P4SMA62CAHM3/H under surge conditions?
The P4SMA62CAHM3/H clamps to a maximum of 85.0 V when subjected to its rated 4.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream ICs (e.g., 75 V-rated transceivers) remain within safe operating area during transient exposure.
Does the P4SMA62CAHM3/H require special PCB layout considerations?
Yes - to achieve the rated 400 W peak pulse power, the P4SMA62CAHM3/H must be mounted on minimum recommended copper pad areas: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal, as specified in Figure 1 of the datasheet. Smaller pads increase thermal impedance and reduce surge capability; routing traces should be short and wide to minimize inductance, and the device must be placed as close as possible to the protected port to avoid voltage overshoot from trace inductance during fast transients.
