Product details
Overview
P4SMA27CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 27 V breakdown voltage (VBR = 25.7–28.4 V 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-M3/61 datasheet, P4SMA27CA-M3/61 pinout, P4SMA27CA-M3/61 application, or P4SMA27CA-M3/61 equivalent, this device delivers verified bidirectional surge suppression with halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification readiness (via HM3 suffix variants), supporting robust ESD and lightning-induced transient protection in space-constrained layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 µs transients up to 400 W (derated to 300 W above 91 V).
Designed for surface-mount assembly on standard 0.2" × 0.2" copper pads, it achieves thermal resistance of 120 °C/W (junction-to-ambient) and supports operating junction temperatures from –65 °C to +150 °C. The SMA (DO-214AC) package provides mechanical robustness while meeting UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 25.7–28.4 V at 1 mA test current - defines precise voltage threshold where avalanche conduction begins in either polarity |
| Stand-off Voltage VWM | 23.1 V - maximum continuous working voltage before leakage exceeds 1 µA; sets safe operating margin below clamping |
| Clamping Voltage VC | 37.5 V at 10.7 A IPPM - limits transient voltage seen by protected circuitry during 10/1000 µs surge |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - sustains high-energy surges without failure; derates linearly above 25 °C ambient |
| Package | SMA (DO-214AC) - low-profile SMD outline with 5.28 mm length, 3.99 mm width, and 2.29 mm height for automated placement |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix), MSL Level 1, JESD201 Class 2 whisker resistant - suitable for lead-free reflow and automotive-grade production |

Use Scenario: Adding secondary-level transient immunity to USB 2.0 VBUS lines in smart home hubs exposed to user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF at 0 V) bidirectional clamp between VBUS and GND, activated only during >23.1 V excursions. Use Value: Preserves signal integrity (no data corruption) while suppressing ±15 kV contact ESD per IEC 61000-4-2 without affecting 480 Mbps signaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ28CA | Higher 600 W PPPM rating; larger SMB (DO-214AA) package (4.5 × 3.9 mm vs. SMA's 5.3 × 4.0 mm); VC = 45.4 V at 13.1 A | Better suited for higher-energy surges but requires larger PCB area; less optimal for ultra-dense layouts | Select when system-level surge testing exceeds 400 W or when thermal margin must be increased beyond 120 °C/W |
| 1.5SMC27CA | Same VBR/VC specs but in larger SMC (DO-214AB) package; 1500 W PPPM; RθJA = 30 °C/W | Used in high-power industrial drives where board space allows and heat sinking is integrated into metal chassis | Choose when junction temperature rise must stay below 30 °C under repeated surges - not feasible with SMA's 120 °C/W |
Compared with SMBJ28CA and 1.5SMC27CA, the P4SMA27CA-M3/61 offers the smallest footprint among 27 V bidirectional TVS diodes with certified 400 W capability, making it optimal for space-constrained designs where thermal management relies on PCB copper rather than heatsinks.

FAQ
What is the maximum clamping voltage of P4SMA27CA-M3/61 under a 10/1000 µs surge?
The P4SMA27CA-M3/61 has a maximum clamping voltage (VC) of 37.5 V at 10.7 A peak pulse current under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and represents the upper limit of voltage imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA27CA-M3/61 suitable for automotive applications?
Yes, P4SMA27CA-M3/61 is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified P4SMA family - with HM3 variants (e.g., P4SMA27CAHM3_A/H) explicitly certified. While the M3/61 variant itself carries commercial-grade qualification, its construction, thermal specs, and surge performance align with automotive subsystem requirements such as body electronics and infotainment power rails.
How does the bidirectional design of P4SMA27CA-M3/61 affect its circuit placement?
The P4SMA27CA-M3/61 has no polarity marking and conducts identically in both directions, so it can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (CAN_H/CAN_L), AC-coupled lines, or ungrounded power rails. Unlike unidirectional TVS diodes, no cathode alignment is needed, simplifying layout and reducing assembly errors.
What is the thermal resistance of P4SMA27CA-M3/61, and how does it impact PCB layout?
P4SMA27CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe operation under repetitive surges, designers must allocate adequate copper area and avoid thermal bottlenecks - e.g., using internal ground planes or thermal vias beneath the SMA pads to lower effective RθJA.
Does P4SMA27CA-M3/61 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, P4SMA27CA-M3/61 meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means it can be processed in standard lead-free reflow ovens without baking or dry-pack requirements - significantly simplifying manufacturing flow and reducing cost for high-mix SMT lines handling both commercial and automotive builds.
