Product details
Overview
P4SMA27CA-E3/61 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 23.1 V standoff voltage (VWM), 25.7–28.4 V breakdown voltage (VBR) at 1 mA, 37.5 V maximum clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA27CA-E3/61 datasheet, P4SMA27CA-E3/61 pinout, P4SMA27CA-E3/61 application, or P4SMA27CA-E3/61 equivalent, key selection considerations include bidirectional clamping capability, 150 °C max junction temperature, RoHS-compliant matte tin terminals, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
The P4SMA27CA-E3/61 operates as a symmetrical avalanche diode with identical forward and reverse clamping behavior, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the low incremental surge resistance supports fast transient suppression during inductive switching events.
Thermally, it exhibits RθJA = 120 °C/W (junction-to-ambient, on minimum pad layout) and RθJL = 30 °C/W (junction-to-lead), allowing reliable operation up to 150 °C junction temperature. The device meets AEC-Q101 qualification when ordered with HE3/HM3 suffixes, though P4SMA27CA-E3/61 itself is commercial-grade RoHS-compliant per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 23.1 V - Maximum continuous working voltage before clamping begins; defines safe operating range for protected circuitry. |
| VBR (Breakdown Voltage) | 25.7–28.4 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 37.5 V at 10.7 A (10/1000 µs) - Peak voltage seen by downstream components during worst-case surge; critical for IC survivability. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capacity under standardized 10/1000 µs transient; enables robust ESD and load-dump protection. |
| IPPM (Peak Pulse Current) | 10.7 A - Maximum non-repetitive surge current handled without degradation; determines minimum trace width and fuse coordination. |
| TJmax | 150 °C - Maximum allowable junction temperature; sets thermal derating limits for high-temperature environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement; compatible with reflow and wave soldering. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (either direction) | Acts as cathode during positive transients and anode during negative transients - symmetrical conduction enables bidirectional clamping. |
| Cathode | Transient current exit point (either direction) | Paired with Anode to form low-impedance path during overvoltage; no fixed polarity marking required on device body. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals, differential buses, and ungrounded lines without polarity concerns. |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-earth) in properly designed layouts. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors. |
| MSL Level 1, 260 °C peak reflow | Eliminates pre-baking requirements and simplifies SMT assembly in high-volume manufacturing. |
| AEC-Q101 qualified variants available | Enables drop-in qualification path for automotive applications using HE3/HM3 suffix versions (not applicable to -E3/61). |
Applications

| Telecom Line Interface Protection | Consumer Appliance Motor Drive Protection |
|

IC Role / Device Role / Timing Role: Primary-level TVS on differential pair, coordinated with GDT or polymer PTC for multi-stage protection. Use Value: Clamps common-mode transients to 37.5 V while preserving signal swing margin for 2.5 V or 3.3 V logic interfaces. |
Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in washing machines, HVAC blowers, or power tools. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to absorb inductive kickback before it stresses H-bridge MOSFETs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Higher VWM (24 V), lower VC (38.9 V), same 400 W rating but SMB package (larger footprint, better thermal dissipation). | Preferred where board space allows larger package and tighter clamping margin is needed near 24 V rails. | Select SMBJ24CA if thermal performance or margin above 24 V system voltage is prioritized over miniaturization. |
| 1.5KE27CA | Through-hole DO-201 package, 1500 W rating, higher VC (45.4 V), slower response due to higher junction capacitance. | Suitable for legacy designs or high-energy surge zones (e.g., AC mains input) where SMT is not required. | Choose 1.5KE27CA only for through-hole prototyping or high-energy primary-side protection; not recommended for signal-line use. |
Compared with SMBJ24CA and 1.5KE27CA, the P4SMA27CA-E3/61 delivers optimal balance of compact SMA footprint, precise 23.1 V standoff, and fast clamping for modern SMT-based signal protection - making it ideal for space-constrained industrial and automotive modules where automated assembly and thermal efficiency are critical.

FAQ
What is the clamping voltage of P4SMA27CA-E3/61 at its rated peak pulse current?
The P4SMA27CA-E3/61 has a maximum clamping voltage (VC) of 37.5 V at 10.7 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and represents the highest voltage imposed on protected circuitry during a worst-case transient event. The P4SMA27CA-E3/61 maintains this clamping level consistently across its operational temperature range, supporting robust design margins for 3.3 V and 5 V logic interfaces.
Is P4SMA27CA-E3/61 suitable for automotive applications?
The P4SMA27CA-E3/61 is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same die and construction as AEC-Q101-qualified variants (e.g., P4SMA27CAHE3_A), the -E3/61 suffix denotes commercial qualification only. For automotive production, engineers must specify the HE3 or HM3 suffix versions; the P4SMA27CA-E3/61 may be used in automotive prototyping or non-safety-critical subsystems where formal qualification is not mandated.
How does the bidirectional configuration of P4SMA27CA-E3/61 affect its PCB layout?
The P4SMA27CA-E3/61 has no polarity marking and functions identically in both directions, simplifying PCB layout by eliminating orientation checks during placement. It requires symmetric 5.0 mm × 5.0 mm copper pads per terminal per Vishay's recommended mounting layout, with no need for ground-plane isolation or directional routing. This symmetry makes the P4SMA27CA-E3/61 especially valuable for differential signal protection such as RS-485 or USB data lines.
What is the maximum operating temperature for P4SMA27CA-E3/61?
The P4SMA27CA-E3/61 has a maximum junction temperature (TJmax) of +150 °C and an operating storage temperature range of –65 °C to +150 °C. Its thermal resistance is RθJA = 120 °C/W on minimum pad layout, meaning ambient temperature must be limited to ~115 °C at full 3.3 W steady-state dissipation. Derating curves in the datasheet confirm usable operation up to 125 °C ambient in typical industrial environments when mounted per specification.
Does P4SMA27CA-E3/61 require special handling for moisture sensitivity?
No - the P4SMA27CA-E3/61 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be processed directly through standard SMT reflow profiles with a peak temperature of 260 °C without baking. This eliminates moisture-related defects like popcorning and reduces manufacturing overhead, making the P4SMA27CA-E3/61 ideal for high-throughput automated assembly lines.
