Product details
Overview
P4SMA62A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping inductive switching transients and ESD events on power rails and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the P4SMA62A-M3/5A datasheet, P4SMA62A-M3/5A pinout, P4SMA62A-M3/5A application, or P4SMA62A-M3/5A equivalent, this device serves as a robust, AEC-Q101-qualified (M3 suffix) overvoltage protection component for automotive power supplies, industrial sensor interfaces, and telecom DC input stages where fast response (<1 ns), low clamping ratio, and halogen-free RoHS compliance are required.
Technical Context
The P4SMA62A-M3/5A operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified VBR range (58.9–65.1 V), with cathode band marking polarity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤1.0 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
Thermal performance is defined by RθJA = 120 °C/W (junction-to-ambient, on minimum pad layout) and RθJL = 30 °C/W (junction-to-lead), enabling reliable operation up to TJ = +150 °C. The device delivers 400 W peak pulse power below 91 V and derates to 300 W above that threshold per JEDEC JESD22-A114 standard test conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A (Bourns) | Same VWM (55.1 V), higher VC (103 V at 3.9 A), SMB package (larger footprint, 5.28 mm × 4.57 mm). | Lower power density (600 W but larger size); less suitable for space-constrained automotive modules. | Select P4SMA62A-M3/5A for tighter board area and halogen-free compliance; choose SMBJ64A only if higher surge margin justifies added PCB real estate. |
| 1.5SMC62A (ON Semiconductor) | Identical VWM (53.0 V), same VC (85.0 V), but SMC (DO-214AB) package (6.22 mm × 4.57 mm) and non-AEC-Q101 commercial grade. | Lacks automotive qualification and halogen-free certification; not approved for under-hood deployment. | Use P4SMA62A-M3/5A where AEC-Q101 and M3 environmental compliance are mandatory; 1.5SMC62A remains viable for cost-sensitive industrial prototypes. |
Compared with SMBJ64A and 1.5SMC62A, the P4SMA62A-M3/5A uniquely combines AEC-Q101 qualification, halogen-free construction, and SMA footprint-enabling direct integration into automotive Tier-1 power modules and high-density telecom boards without layout revision or compliance revalidation.

FAQ
What is the maximum clamping voltage of the P4SMA62A-M3/5A under a 10/1000 µs surge?
The P4SMA62A-M3/5A exhibits a maximum clamping voltage (VC) of 85.0 V when subjected to a 4.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC JESD22-A114 and represents the upper bound of voltage seen by downstream circuitry during standardized surge events. The P4SMA62A-M3/5A maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) and is validated for repetitive surge duty cycles up to 0.01 %.
Is the P4SMA62A-M3/5A suitable for automotive applications?
Yes, the P4SMA62A-M3/5A is AEC-Q101 qualified and carries the M3 suffix, indicating halogen-free, RoHS-compliant construction certified for automotive use. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance per AEC-Q101 Rev D. The P4SMA62A-M3/5A is deployed in engine control units, body electronics, and ADAS power supplies where sustained operation at +150 °C and immunity to load-dump transients are required.
What does the "M3" suffix signify in P4SMA62A-M3/5A?
The "M3" suffix in P4SMA62A-M3/5A denotes halogen-free, RoHS-compliant construction meeting JEDEC J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements. Unlike the E3 variant, M3 uses bromine- and chlorine-free flame retardants in the molding compound and matte tin plating compliant with J-STD-002 solderability standards. The P4SMA62A-M3/5A is fully compatible with lead-free reflow profiles peaking at 260 °C.
How does the P4SMA62A-M3/5A differ from bidirectional variants like P4SMA62CA?
The P4SMA62A-M3/5A is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where current flows in one direction. In contrast, P4SMA62CA is bidirectional, lacks polarity marking, and provides symmetrical clamping for AC-coupled or floating signal lines. The P4SMA62A-M3/5A has VWM = 53.0 V and VBR = 58.9–65.1 V, whereas P4SMA62CA specifies VWM = 45.0 V and VBR = 50.0–55.0 V-making them non-interchangeable without circuit redesign.
What is the thermal resistance of the P4SMA62A-M3/5A, and how does it affect PCB layout?
The P4SMA62A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended copper pad layout (0.2" × 0.2" per terminal). To maintain TJ ≤ +150 °C under 3.3 W steady-state dissipation, designers must ensure adequate copper area and airflow. The P4SMA62A-M3/5A benefits from thermal vias under pads and connection to internal ground planes-especially critical in automotive modules operating at elevated ambient temperatures.
