Product details
Overview
P4SMA10A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 10 V breakdown voltage (VBR = 9.5–10.5 V at IT = 1.0 mA), 14.5 V clamping voltage (VC) at 27.6 A peak pulse current, and 400 W peak pulse power (10/1000 µs waveform). It protects signal lines and IC inputs in consumer, industrial, and telecom systems against ESD and inductive switching transients.
For engineers reviewing the P4SMA10A-E3/5A datasheet, P4SMA10A-E3/5A pinout, P4SMA10A-E3/5A application, or P4SMA10A-E3/5A equivalent, this device delivers verified clamping performance, AEC-Q101 qualification readiness (via HE3/HM3 variants), RoHS-compliant matte tin terminations, and MSL Level 1 moisture sensitivity - critical for high-reliability automated SMT assembly and automotive-grade design-in.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias (VWM = 8.55 V), it exhibits ≤10 µA reverse leakage; when transient voltage exceeds VBR, it avalanches rapidly (<1 ns response) to clamp at VC = 14.5 V, diverting up to 27.6 A (10/1000 µs) away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
Thermally, it features RθJA = 120 °C/W (junction-to-ambient, on minimum pad layout) and RθJL = 30 °C/W (junction-to-lead), with TJ(max) = +150 °C and operating range from –65 °C to +150 °C. The cathode band identifies polarity, and its SMA package supports J-STD-002/JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications

Use Scenario: Guarding CC1/CC2 configuration channel pins in portable chargers against ESD (IEC 61000-4-2 ±15 kV contact) and cable-insertion spikes. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS (CJ ≈ 100 pF at VWM) placed inline with CC line, referenced to GND. Use Value: Preserves USB-C enumeration timing (sub-100 ms) by avoiding signal distortion; 14.5 V clamping prevents damage to 5 V-tolerant CC logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMA package, identical VBR (9.5–10.5 V), but lower PPPM = 400 W (same rating), higher VC = 16.0 V at same IPPM | Less effective clamping margin for 3.3 V/5 V logic; suitable where board space allows larger footprint alternatives | Select SMAJ10A only if existing layout uses legacy SMAJ footprint and VC margin ≥16 V is acceptable |
| 1.5SMC10A | Higher-power SMC package (PPPM = 1500 W), same VBR/VWM, but VC = 17.0 V at 87.2 A; larger footprint (7.11 × 6.22 mm vs. SMA 4.5 × 2.79 mm) | Overkill for signal-line protection; appropriate for primary-side AC/DC input or 24 V bus protection | Choose 1.5SMC10A only when surge energy exceeds 400 W or PCB layout accommodates SMC and requires higher IPPM |
Compared with SMAJ10A and 1.5SMC10A, P4SMA10A-E3/5A offers optimal balance of compact SMA footprint, tight 14.5 V clamping, and verified 400 W surge handling - making it preferred for space-constrained, low-voltage signal protection where minimal VC overshoot is critical.

FAQ
What is the breakdown voltage tolerance for P4SMA10A-E3/5A?
The P4SMA10A-E3/5A has a specified breakdown voltage range of 9.5 V to 10.5 V at 1.0 mA test current, representing ±5 % tolerance around the nominal 10 V rating. This tight VBR window ensures predictable turn-on behavior during transient events and supports accurate system-level overvoltage margining. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's 88367 datasheet revision 09-Jan-2024.
Is P4SMA10A-E3/5A RoHS-compliant and halogen-free?
Yes, P4SMA10A-E3/5A carries the "E3" suffix, indicating RoHS-compliance per EU Directive 2011/65/EU and exemption 7a, with matte tin-plated leads and UL 94 V-0 molding compound. It is not halogen-free; for halogen-free compliance, select the "M3" variant (e.g., P4SMA10A-M3/5A), which meets IEC 61249-2-21 requirements and contains <900 ppm bromine and <900 ppm chlorine.
What is the maximum clamping voltage of P4SMA10A-E3/5A under surge conditions?
The maximum clamping voltage (VC) of P4SMA10A-E3/5A is 14.5 V, measured at its rated peak pulse current of 27.6 A using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - critical for ensuring compatibility with 3.3 V and 5 V logic interfaces.
Does P4SMA10A-E3/5A meet AEC-Q101 for automotive use?
The base P4SMA10A-E3/5A is commercial-grade and not AEC-Q101 qualified. However, Vishay offers automotive-qualified versions under the HE3 (RoHS-compliant, AEC-Q101) and HM3 (halogen-free, RoHS-compliant, AEC-Q101) ordering codes - e.g., P4SMA10AHE3_A/5A. These variants undergo extended stress testing per AEC-Q101 Rev D and are intended for automotive body electronics, infotainment, and ADAS sensor interfaces.
What is the thermal resistance of P4SMA10A-E3/5A, and how does it affect layout?
P4SMA10A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C during repetitive surges, PCB layout must provide adequate copper area and avoid excessive trace length; increasing pad size or adding thermal vias reduces RθJA and improves power handling reliability.
