Product details
Overview
P4SMA47A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping transient overvoltages on power and signal lines. It features a 47 V breakdown voltage (VBR = 44.7–49.4 V at 1 mA), 40.2 V standoff voltage (VWM), 64.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P4SMA47A-M3/61 datasheet, P4SMA47A-M3/61 pinout, P4SMA47A-M3/61 application, or P4SMA47A-M3/61 equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, halogen-free RoHS-compliant construction (M3 suffix), AEC-Q101 qualification readiness, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
The P4SMA47A-M3/61 employs a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance ensures stable clamping performance under repetitive 10/1000 µs pulses at 0.01% duty cycle, with thermal resistance of 120 °C/W (junction-to-ambient) enabling operation up to 150 °C junction temperature.
Designed for unidirectional protection only, it exhibits 1.0 µA maximum reverse leakage at VWM, 0.101 %/°C temperature coefficient of VBR, and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). Polarity is marked by a cathode band; no marking applies to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ47A-E3/52 (Vishay) | Same VBR range (44.7–49.4 V) but SMB (DO-214AA) package; 600 W PPPM; higher thermal resistance (RθJA = 140 °C/W) | Higher power handling but larger footprint; less suitable for space-constrained layouts requiring SMA | Select when higher surge margin is needed and PCB area permits SMB outline |
| 1.5SMC47A (ON Semiconductor) | Identical electrical specs (VBR, VWM, VC, PPPM) and SMA package; rated for 150 °C TJ; not AEC-Q101 qualified in base M3 variant | Drop-in replacement electrically; lacks AEC-Q101 documentation path unless specified with automotive suffix | Choose for cost-sensitive commercial designs where automotive qualification is not required |
Compared with SMBJ47A-E3/52, P4SMA47A-M3/61 offers tighter board space utilization and lower thermal resistance (120 vs. 140 °C/W); versus 1.5SMC47A, it provides verified halogen-free and AEC-Q101-ready construction, making it preferable for automotive-tier-1 supply chain compliance.

FAQ
What is the breakdown voltage tolerance of P4SMA47A-M3/61?
The P4SMA47A-M3/61 has a breakdown voltage VBR specified from 44.7 V to 49.4 V at 1 mA test current, representing a ±5% tolerance around the nominal 47 V rating. This tight spread ensures predictable clamping behavior across production lots and supports reliable design margins in overvoltage protection circuits.
Is P4SMA47A-M3/61 suitable for automotive applications?
Yes - the P4SMA47A-M3/61 uses halogen-free, RoHS-compliant materials (M3 suffix) and is part of the AEC-Q101-qualified P4SMA family. While the base P4SMA47A-M3/61 is commercial-grade, Vishay offers automotive variants (e.g., P4SMA47AHM3_A/H) with full AEC-Q101 certification; consult ordering codes for qualified versions.
What is the maximum clamping voltage of P4SMA47A-M3/61 under surge conditions?
The P4SMA47A-M3/61 has a maximum clamping voltage VC of 64.8 V at 6.2 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is critical for ensuring downstream components remain within safe operating limits.
Does P4SMA47A-M3/61 require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 400 W pulse power. Minimizing trace inductance and ensuring solid thermal connection to copper pour improves surge handling. The SMA (DO-214AC) outline requires precise pad dimensions per the mechanical drawing in document 88367.
How does the temperature coefficient affect P4SMA47A-M3/61 performance?
The P4SMA47A-M3/61 has a VBR temperature coefficient of +0.101 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At 125 °C, VBR rises ~10.1 V above its 25 °C value - a key factor when designing protection margins for high-temperature environments like engine control units or industrial drives.
