Product details
Overview
P4SMA100CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 100 V standoff voltage (VWM), 114–126 V breakdown voltage (VBR) at 1 mA, 137 V maximum clamping voltage at 2.2 A peak pulse current, and 400 W peak pulse power capability with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom systems.
For engineers reviewing the P4SMA100CA-M3/61 datasheet, P4SMA100CA-M3/61 pinout, P4SMA100CA-M3/61 application, or P4SMA100CA-M3/61 equivalent, key selection criteria include bidirectional clamping performance, 137 V VC under 2.2 A IPPM, M3 halogen-free RoHS compliance, AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical bidirectional conduction - no polarity marking required. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes on bidirectional data or AC-coupled lines.
The P4SMA100CA-M3/61 delivers 400 W peak pulse power up to 91 V and 300 W above 91 V per JEDEC JESD22-A114F testing conditions, with thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W. It supports continuous operation from –65 °C to +150 °C junction temperature and meets MSL Level 1 reflow profile (260 °C peak).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Higher 600 W PPPM rating, larger SMB (DO-214AA) package (5.3 mm × 4.6 mm), 140 V VC at 3.5 A | Better suited for higher-energy surges but requires larger board area and different pad layout | Select when system-level surge test levels exceed IEC 61000-4-5 Level 4 and PCB space permits larger footprint |
| 1.5KE100CA | Through-hole TO-218 package, 1500 W PPPM, 143 V VC at 10.5 A, higher thermal mass | Used in legacy designs or high-power AC mains protection where SMT is not feasible | Choose only for through-hole prototyping or repair scenarios - not drop-in SMT replacement |
Compared with P4SMA100CA-M3/61, SMBJ100CA offers greater surge margin in same voltage class but increases PCB real estate; 1.5KE100CA provides superior energy handling but eliminates SMT automation benefits and requires manual assembly - neither is pin-compatible, and both demand layout revision.

FAQ
What is the clamping voltage of P4SMA100CA-M3/61 under standard surge conditions?
The P4SMA100CA-M3/61 has a maximum clamping voltage (VC) of 137 V when subjected to a 10/1000 µs waveform at 2.2 A peak pulse current (IPPM). This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA100CA-M3/61 suitable for automotive applications?
P4SMA100CA-M3/61 itself is commercial-grade, but Vishay offers AEC-Q101 qualified versions under HM3 suffix (e.g., P4SMA100CAHM3_B/H). The P4SMA100CA-M3/61 shares identical electrical specs and package dimensions, allowing design reuse - however, full automotive qualification requires the HM3 variant with documented stress-test reports and PPAP documentation.
Does P4SMA100CA-M3/61 require polarity-aware PCB layout?
No - P4SMA100CA-M3/61 is a bidirectional TVS diode with symmetrical terminals and no cathode band marking. Its internal structure allows equal clamping performance regardless of voltage polarity, making it ideal for AC signal lines, differential buses, or unmarked PCB footprints where orientation cannot be guaranteed during automated placement.
What is the thermal resistance of P4SMA100CA-M3/61, and how does it affect power derating?
P4SMA100CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. At ambient temperatures above 25 °C, its 3.3 W steady-state power dissipation must be linearly derated - for example, at 75 °C ambient, usable PD drops to ~1.65 W - requiring careful thermal pad design and airflow consideration in enclosed enclosures.
How does the M3 suffix impact environmental compliance and assembly process for P4SMA100CA-M3/61?
The M3 suffix on P4SMA100CA-M3/61 indicates halogen-free, RoHS-compliant construction using UL 94 V-0 rated molding compound and matte tin-plated leads. It fully supports lead-free reflow profiles up to 260 °C peak (MSL Level 1), eliminating moisture sensitivity concerns and enabling direct placement into standard SMT lines without baking or special handling.
