Product details
Overview
P4SMA62AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 53.0 V standoff voltage (VWM), and 85.0 V clamping voltage (VC) at 4.7 A peak pulse current. It delivers 400 W peak pulse power (10/1000 µs waveform) and is AEC-Q101 qualified for automotive applications including sensor signal line protection against inductive switching transients.
For engineers reviewing the P4SMA62AHM3_A/I datasheet, P4SMA62AHM3_A/I pinout, P4SMA62AHM3_A/I application, or P4SMA62AHM3_A/I equivalent, this part serves as a halogen-free, RoHS-compliant, automotive-grade TVS with verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for ECU, ADAS camera interface, and infotainment power rail protection designs.
Technical Context
The P4SMA62AHM3_A/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and stable clamping under repetitive transient stress. Its thermal resistance (RθJA = 120 °C/W) and junction temperature limit (TJ = 150 °C) support operation on standard 0.2" × 0.2" copper pads without forced cooling.
Designed per ANSI/IEEE C62.35, it meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance. The cathode band marking enables unambiguous polarity identification during automated placement, and its 3.3 W steady-state power dissipation (PD) supports continuous biasing in low-leakage protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines reliable avalanche initiation threshold across production lot and temperature range |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe margin below system rail |
| VC @ IPPM | 85.0 V at 4.7 A - clamping voltage limits downstream IC stress during 10/1000 µs surge; critical for 60 V-rated MOSFET gate protection |
| PPPM | 400 W (10/1000 µs) - peak transient energy absorption capacity; derates to 300 W above 91 V per spec |
| IFSM | 40 A (8.3 ms half-sine) - surge current rating for single-event overvoltage events like load dump |
| TJ max. | 150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 5.0 mm × 5.0 mm pad footprint and MSL Level 1 handling |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case with matte tin-plated leads, UL 94 V-0 flammability rating, and cathode band marking for unidirectional polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or lower-potential node; completes clamping path during positive transients |
| Cathode | Avalanche breakdown terminal | Connected to protected line (e.g., CAN_H, LIN, sensor VOUT); conducts when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness - required for ECU and ADAS modules |
| Halogen-free & RoHS-compliant | Meets global environmental compliance mandates without compromising surge performance or thermal stability |
| Glass passivated junction | Ensures consistent VBR tolerance and low leakage (<1 µA at VWM) across -65 °C to +150 °C operating range |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin for 3.3 V/5 V logic |
| MSL Level 1 (260 °C peak) | Enables standard reflow soldering without pre-baking - reduces manufacturing complexity and cost |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/5A | VBR = 60.8–67.5 V; VC = 103 V at 3.9 A; 400 W rating; same SMA package but non-AEC-Q101, commercial grade | Lacks automotive qualification and halogen-free construction; suitable for industrial/commercial designs only | Select when AEC-Q101 is not required and higher clamping voltage is acceptable for 64 V systems |
| 1.5SMC62AHE3_A | VBR = 58.9–65.1 V; VC = 101 V at 14.9 A; 1500 W rating; larger SMC (DO-214AB) package | Higher power handling but 2.5× larger footprint; requires PCB layout change and higher thermal mass | Choose for systems needing >400 W surge capability where board space permits SMC package |
Compared with SMAJ64A-E3/5A, P4SMA62AHM3_A/I offers tighter VC (85.0 V vs. 103 V) and automotive qualification, enabling safer protection of 60 V-rated components; versus 1.5SMC62AHE3_A, it trades surge capacity for compact size and direct drop-in compatibility in space-constrained automotive modules.

FAQ
What is the clamping voltage of P4SMA62AHM3_A/I at its rated peak pulse current?
The P4SMA62AHM3_A/I has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream 60 V-rated components. The P4SMA62AHM3_A/I maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P4SMA62AHM3_A/I suitable for automotive applications?
Yes, P4SMA62AHM3_A/I is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials. Its qualification covers temperature cycling, high-temperature reverse bias, and mechanical shock testing required for under-hood and cabin-mounted ECUs. The P4SMA62AHM3_A/I is explicitly listed in Vishay's automotive-grade ordering codes (HM3 suffix) and supports automotive safety-critical signal and power line protection.
What does the "HM3" suffix indicate in P4SMA62AHM3_A/I?
The "HM3" suffix in P4SMA62AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates halogen-free molding compound, "M3" confirms RoHS compliance and JESD201 Class 2 whisker resistance, and the "_A/I" specifies revision A and 13-inch tape-and-reel packaging (7500 units per reel). This distinguishes it from commercial-grade "E3" or non-automotive "M3" variants.
How does P4SMA62AHM3_A/I compare to bidirectional TVS diodes in the same series?
P4SMA62AHM3_A/I is unidirectional and features a cathode band for polarity identification; bidirectional variants (e.g., P4SMA62CA) lack polarity marking and conduct in both directions. The P4SMA62AHM3_A/I offers lower leakage (<1 µA at VWM) and tighter VBR tolerance than equivalent bidirectional parts, making it preferred for DC-biased lines like power rails or unidirectional data buses where reverse conduction must be avoided.
What is the maximum steady-state power dissipation for P4SMA62AHM3_A/I?
The P4SMA62AHM3_A/I has a maximum steady-state power dissipation (PD) of 3.3 W at TA = 50 °C on an infinite heatsink. In typical PCB layouts with 0.2" × 0.2" copper pads per terminal, derating applies per Figure 2 in the datasheet; at 70 °C ambient, usable PD drops to ~2.2 W. This rating governs continuous leakage-based heating and must be considered alongside transient duty cycle in thermally constrained designs.
