Product details
Overview
P4SMA110AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 110 V breakdown voltage (VBR = 105–116 V at IT = 1.0 mA), 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and automotive electronics.
For engineers reviewing the P4SMA110AHE3/5A datasheet, P4SMA110AHE3/5A pinout, P4SMA110AHE3/5A application, or P4SMA110AHE3/5A equivalent, this device delivers AEC-Q101 qualification, low incremental surge resistance, fast response time, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly on consumer, telecom, and embedded control systems.
Technical Context
This unidirectional TVS operates with a cathode-band polarity marking and exhibits a 0.107 %/°C temperature coefficient of VBR, ensuring stable clamping over temperature. Its glass-passivated junction enables robust surge handling up to 40 A IFSM (8.3 ms half-sine) and 150 °C maximum junction temperature.
The device is rated for 3.3 W steady-state power dissipation at TA = 50 °C on infinite heatsink, with thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive underhood applications.
Key Specifications

|---|---|
Use Scenario: Protecting 12 V/24 V power rails in engine control units (ECUs) and body control modules (BCMs) from load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between supply rail and chassis ground to clamp transients exceeding 94 V. Use Value: Limits voltage to ≤152 V during 400 W surges, preventing damage to microcontrollers and CAN transceivers operating at 5 V or 3.3 V logic levels. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops or 0–10 V sensors) in factory automation PLCs and motor drives. IC Role / Device Role / Timing Role: TVS connected across signal and return path to suppress ESD and switching noise coupled into sensor interfaces. Use Value: Clamps fast transients within nanoseconds while adding <1 pF junction capacitance - preserving signal integrity and bandwidth. |
| Telecom DC Power Input | Consumer Device USB/Power Port |
Use Scenario: Safeguarding primary DC input (e.g., 48 V PoE or AC/DC adapter outputs) in base station radios and network switches. IC Role / Device Role / Timing Role: Standoff-rated TVS installed upstream of DC-DC converters to absorb repetitive surges from grid coupling or lightning-induced induction. Use Value: Withstands 0.01 % duty cycle repetitive 400 W pulses and maintains <1 µA leakage at 94 V - minimizing standby power loss. |
Use Scenario: Adding secondary-level surge immunity to USB-C PD ports and external power inputs in smart home hubs and portable medical devices. IC Role / Device Role / Timing Role: Low-profile SMA-packaged TVS placed adjacent to connector to intercept ESD (IEC 61000-4-2 ±15 kV contact) before reaching PMIC or battery charger IC. Use Value: AEC-Q101 qualification ensures consistent performance across temperature extremes encountered in uncontrolled indoor environments. |
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 VBR range (105–116 V), but SMB package (DO-214AA); 600 W PPPM; higher IPPM (3.3 A) | Larger footprint; better thermal dissipation but incompatible with ultra-dense layouts requiring SMA | Select SMBJ110A only if board space allows larger package and higher surge margin is required |
| 1.5SMC110A | Same VBR and unidirectional function, but SMC (DO-214AB) package; 1500 W PPPM; VC = 177 V at 8.5 A | Higher clamping voltage and significantly larger thermal mass - suited for primary-level protection, not signal-line refinement | Choose 1.5SMC110A for front-end bulk protection; retain P4SMA110AHE3/5A for secondary-stage precision clamping |
Compared with SMBJ110A and 1.5SMC110A, the P4SMA110AHE3/5A offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and tight 152 V clamping - making it preferred for space-constrained, automotive-grade secondary protection where layout density and thermal management are jointly critical.

FAQ
What is the maximum clamping voltage of the P4SMA110AHE3/5A under a 10/1000 µs surge?
The P4SMA110AHE3/5A has a maximum clamping voltage (VC) of 152 V at 2.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and ensures downstream components experience limited overvoltage stress during transient events. The P4SMA110AHE3/5A maintains this clamping performance across its specified operating temperature range.
Is the P4SMA110AHE3/5A qualified for automotive applications?
Yes, the P4SMA110AHE3/5A is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and documented in Vishay's P4SMA series datasheet revision 09-Jan-2024. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock - validating suitability for automotive underhood and cabin electronics. The P4SMA110AHE3/5A meets these requirements in its SMA (DO-214AC) package.
What does the "HE3/5A" suffix indicate in P4SMA110AHE3/5A?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "/5A" specifies packaging in 13-inch diameter plastic tape and reel containing 7500 units. This format supports high-volume SMT placement and aligns with Vishay's ordering convention for automotive-grade parts. The P4SMA110AHE3/5A thus combines reliability certification with production-ready logistics.
How does the P4SMA110AHE3/5A compare to bidirectional TVS diodes like P4SMA110CA?
The P4SMA110AHE3/5A is unidirectional and features a cathode band for polarity identification, whereas P4SMA110CA is bidirectional with no polarity marking and symmetric breakdown in both directions. The P4SMA110AHE3/5A is intended for DC rail protection where polarity is fixed; using it in AC or floating signal paths would require careful circuit analysis. Its VBR and VC values apply only in reverse bias.
What is the thermal resistance and power derating behavior of the P4SMA110AHE3/5A?
The P4SMA110AHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. Its 400 W peak pulse power rating is derated linearly above TA = 25 °C per Figure 2 in the datasheet, dropping to zero at ~150 °C ambient. For continuous operation, the 3.3 W power dissipation limit applies at TA = 50 °C on infinite heatsink. The P4SMA110AHE3/5A must be mounted on minimum recommended 5.0 mm × 5.0 mm copper pads for rated performance.
