Product details
Overview
P4SMA16A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features a 16 V standoff voltage (VWM), 17.8 V maximum clamping voltage (VC) at 1 A peak pulse current, 400 W peak pulse power rating (10/1000 μs), and operates across -65 °C to +150 °C junction temperature range - ideal for protecting MOSFET gates and sensor I/O in automotive control modules.
For engineers reviewing the P4SMA16A-M3/61 datasheet, P4SMA16A-M3/61 pinout, P4SMA16A-M3/61 application, or P4SMA16A-M3/61 equivalent, this device is evaluated for robustness against inductive switching surges, lightning-induced transients, and ESD events per IEC 61000-4-2/4-4/4-5, with halogen-free RoHS compliance and J-STD-020 MSL Level 1 qualification.
Technical Context
The P4SMA16A-M3/61 employs a glass-passivated silicon junction optimized for low incremental surge resistance and sub-nanosecond response time. Its unidirectional polarity uses a cathode band marking and delivers stable clamping performance under repetitive 10/1000 μs pulses at 0.01% duty cycle, derated above 25 °C per Fig. 2 of the datasheet.
Thermal design relies on RθJA = 120 °C/W (typ.) and RθJL = 30 °C/W (typ.), requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 400 W pulse handling. It meets AEC-Q101 qualification when ordered with HE3/HM3 suffixes, though P4SMA16A-M3/61 itself is commercial-grade halogen-free RoHS-compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 1 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC-level stress limits. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard 10/1000 μs waveform; enables protection of 12 V automotive rails. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves battery life and signal integrity in always-on sensor interfaces. |
| TJ max. | +150 °C - Enables operation in under-hood automotive environments and industrial motor drive enclosures. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 2.54 mm lead pitch; compatible with automated pick-and-place and reflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A (Bourns) | Same VWM (13.6 V), higher VC (25.5 V), SMB package (DO-214AA), 600 W PPPM rating. | Larger footprint; better suited for higher-energy 24 V industrial rails where space permits. | Select SMBJ16A when surge energy exceeds 400 W or board layout allows larger SMB package. |
| 1.5SMC16A (ON Semiconductor) | Identical VWM (13.6 V) and VC (22.5 V), but SMC (DO-214AB) package, 1500 W PPPM, higher IFSM (200 A). | Requires larger pad layout; intended for primary-level protection in power supply inputs. | Choose 1.5SMC16A for front-end AC/DC or DC/DC converter input stages needing higher surge margin. |
Compared with P4SMA16A-M3/61, SMBJ16A offers greater pulse power headroom in a slightly larger package, while 1.5SMC16A provides significantly higher energy handling in a physically larger SMC outline - making P4SMA16A-M3/61 optimal for space-constrained secondary-side protection where 400 W suffices.

FAQ
What is the maximum clamping voltage of the P4SMA16A-M3/61 under a 10/1000 μs surge?
The P4SMA16A-M3/61 has a maximum clamping voltage (VC) of 22.5 V when subjected to a 1 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 88367) and represents the upper voltage limit imposed on the protected circuit during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4SMA16A-M3/61 suitable for automotive applications requiring AEC-Q101 qualification?
The P4SMA16A-M3/61 is halogen-free and RoHS-compliant but is not AEC-Q101 qualified. For automotive use, Vishay offers AEC-Q101 variants under ordering codes such as P4SMA16AHE3_A or P4SMA16AHM3_A. The P4SMA16A-M3/61 remains appropriate for non-safety-critical commercial or industrial applications where AEC-Q101 is not mandated.
What does the "M3" suffix indicate in P4SMA16A-M3/61?
The "M3" suffix in P4SMA16A-M3/61 denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It also signifies compliance with J-STD-020 MSL Level 1, allowing direct placement into lead-free reflow ovens with a peak temperature of 260 °C - distinguishing it from the E3 (RoHS, non-halogen-free) and HE3/HM3 (AEC-Q101 qualified) variants.
How does the P4SMA16A-M3/61 compare to bidirectional TVS diodes like P4SMA16CA?
The P4SMA16A-M3/61 is unidirectional and features a cathode band marking, whereas P4SMA16CA is bidirectional with no polarity marking. Unidirectional devices offer lower leakage (<1 μA) and tighter VBR tolerance, making P4SMA16A-M3/61 preferable for DC power rail protection. Bidirectional versions are reserved for AC-coupled or differential signal lines like RS-485 where polarity reversal occurs.
What PCB pad layout is recommended for reliable thermal performance of the P4SMA16A-M3/61?
Vishay specifies mounting the P4SMA16A-M3/61 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 400 W peak pulse power. Smaller pads reduce thermal dissipation and may cause premature failure under repeated surges. The SMA (DO-214AC) outline requires 2.54 mm lead spacing and accommodates standard stencil apertures for consistent solder paste deposition.
