Product details
Overview
P4SMA110A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 110 V breakdown voltage (VBR min/max: 105–116 V), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage (VC) at 2.0 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 power supplies and telecom line cards.
For engineers reviewing the P4SMA110A-M3/5A datasheet, P4SMA110A-M3/5A pinout, P4SMA110A-M3/5A application, or P4SMA110A-M3/5A equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification availability in related variants.
Technical Context
The P4SMA110A-M3/5A operates as a unidirectional clamping device with glass-passivated junction, responding within picoseconds to transient overvoltages. Its 105–116 V breakdown range ensures stable triggering above 94.0 V operating voltage while limiting surge energy to ≤152 V across 2.0 A IPPM under standardized 10/1000 µs waveform conditions.
Thermal performance is defined by 120 °C/W junction-to-ambient thermal resistance (RθJA) and 30 °C/W junction-to-lead (RθJL), requiring minimum 0.2" × 0.2" copper pads per terminal for rated 400 W pulse handling. The cathode band marking identifies polarity, and it meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same VWM (94 V), higher VC (187 V @ 2.2 A), SMB package (larger footprint, 1.6 mm height vs. SMA's 1.1 mm) | Lower clamping ratio (VC/VBR ≈ 1.7 vs. 1.4 for P4SMA110A-M3/5A) increases downstream stress | Select when board space allows larger package and higher surge margin is prioritized over tight clamping |
| 1.5SMC110A | Same VBR range, 1500 W rating but larger SMC (DO-214AB) package; 1.0 W steady-state dissipation vs. 3.3 W | Designed for higher-energy, lower-frequency transients; less suitable for fast repetitive ESD/EFT | Prefer for legacy designs using SMC footprints or where 1.5 kW single-pulse rating is mandatory |
Compared with SMBJ110A and 1.5SMC110A, the P4SMA110A-M3/5A delivers tighter clamping (152 V), lower profile (SMA), and higher steady-state power handling (3.3 W), making it optimal for space-constrained industrial and telecom PCBs requiring precise voltage limiting and automated assembly compatibility.

FAQ
What is the maximum clamping voltage of the P4SMA110A-M3/5A under standard test conditions?
The P4SMA110A-M3/5A has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs waveform at 2.0 A peak pulse current (IPPM). This value is measured per JEDEC standards and reflects the upper voltage limit imposed on protected circuits during transient events - critical for ensuring downstream ICs remain within safe operating voltage margins. The P4SMA110A-M3/5A achieves this with a clamping ratio of ~1.4 relative to its nominal breakdown voltage.
Is the P4SMA110A-M3/5A suitable for automotive applications?
The P4SMA110A-M3/5A itself is not AEC-Q101 qualified, but Vishay offers automotive-grade variants under ordering codes like P4SMA110AHM3_A/I (halogen-free, AEC-Q101 qualified). The P4SMA110A-M3/5A shares identical electrical characteristics and SMA packaging, making it suitable for non-automotive industrial use; for automotive deployment, the HM3-suffixed AEC-Q101 version of P4SMA110A-M3/5A must be specified to meet qualification requirements.
What does the "M3" suffix indicate in P4SMA110A-M3/5A?
The "M3" suffix in P4SMA110A-M3/5A denotes halogen-free, RoHS-compliant construction meeting IEC 61249-2-21 requirements, with matte tin-plated leads qualified to JESD201 Class 2 for whisker resistance. It also signifies commercial-grade temperature rating (–65 °C to +150 °C) and compliance with UL 94 V-0 flammability standard - distinguishing it from E3 (standard RoHS) and HM3 (AEC-Q101 + halogen-free) variants.
How does the P4SMA110A-M3/5A compare to bidirectional TVS diodes like P4SMA110CA?
The P4SMA110A-M3/5A is unidirectional and intended for DC line protection where polarity is fixed (e.g., 48 V supply rails), offering lower leakage and sharper breakdown knee than bidirectional types. In contrast, P4SMA110CA provides symmetrical clamping for AC or floating signal lines but exhibits higher reverse leakage at VWM. The P4SMA110A-M3/5A's cathode band marking enables correct orientation during placement - essential for proper unidirectional clamping function.
What PCB layout guidance applies to the P4SMA110A-M3/5A to achieve full 400 W rating?
To achieve the full 400 W peak pulse power rating, the P4SMA110A-M3/5A must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's datasheet Fig. 2 derating curve. Trace inductance must be minimized - short, wide traces directly connecting anode/cathode to ground/power planes - and thermal vias under pads improve heat dissipation. The P4SMA110A-M3/5A's RθJA of 120 °C/W assumes this layout; reduced copper area lowers surge capability proportionally.
