Product details
Overview
P4SMA150AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 150 V standoff voltage (VWM), 143–158 V breakdown voltage (VBR) at 1 mA, and 207 V clamping voltage (VC) at 1.4 A peak pulse current (IPPM), designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P4SMA150AHE3/61 datasheet, P4SMA150AHE3/61 pinout, P4SMA150AHE3/61 application, or P4SMA150AHE3/61 equivalent, this device delivers AEC-Q101 qualification, 400 W peak pulse power (10/1000 µs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECU and powertrain subsystem designs.
Technical Context
The P4SMA150AHE3/61 operates as a unidirectional avalanche-clamping TVS diode with glass-passivated junction, enabling fast response (<1 ns) to voltage transients and stable clamping performance across -65 °C to +150 °C junction temperature range. Its 120 °C/W junction-to-ambient thermal resistance requires minimum 0.2" × 0.2" copper pads for rated 400 W pulse handling.
It features a cathode-band polarity marking, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. The device is RoHS-compliant and qualified to AEC-Q101 for automotive applications, with no derating required up to 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 207 V at IPPM = 1.4 A (10/1000 µs) - Peak voltage seen by protected circuit under full-rated surge; limits stress on downstream components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | Same VWM (128 V), but SMB package (DO-214AA); 600 W PPPM rating; RθJA = 85 °C/W | Higher power handling and lower thermal resistance; requires larger PCB footprint | Select when higher surge margin or improved thermal performance is needed without layout change constraints |
| 1.5SMC150AHE3/A | Same VWM/VBR/VC specs; SMC (DO-214AB) package; 1500 W PPPM; RθJA = 50 °C/W | Triple the pulse power rating; suited for primary-level protection in harsher environments | Choose for front-end protection stages where IEC 61000-4-5 Level 5 compliance is required |
Compared with P4SMA150AHE3/61, SMBJ150A-E3/52 offers greater thermal efficiency in space-constrained layouts, while 1.5SMC150AHE3/A provides significantly higher surge robustness at the cost of larger footprint - both retain identical electrical clamping behavior but differ in package scalability and power envelope.

FAQ
What is the maximum clamping voltage of the P4SMA150AHE3/61 under a 10/1000 µs surge?
The P4SMA150AHE3/61 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 1.4 A with a 10/1000 µs waveform. This value is measured under standardized test conditions with the device mounted on 0.2" × 0.2" copper pads and represents the highest voltage imposed on the protected circuit during full-rated transient events. The P4SMA150AHE3/61 maintains this clamping performance across its specified operating temperature range.
Is the P4SMA150AHE3/61 qualified for automotive applications?
Yes, the P4SMA150AHE3/61 carries AEC-Q101 qualification, confirming its suitability for automotive electronic systems including engine control, body electronics, and infotainment power rails. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction. The P4SMA150AHE3/61 undergoes stress testing for temperature cycling, high-temperature reverse bias, and surge endurance per JESD47 requirements.
What is the standoff voltage (VWM) rating of the P4SMA150AHE3/61?
The P4SMA150AHE3/61 has a maximum working peak reverse voltage (VWM) of 128 V, meaning it remains in high-impedance blocking mode up to this DC or RMS voltage level. This rating ensures reliable operation on 100–120 V nominal systems such as telecom -48 V feeds with ripple or automotive 24 V systems with load-dump overshoot margins. The P4SMA150AHE3/61 exhibits only 1.0 µA maximum reverse leakage at this voltage.
Does the P4SMA150AHE3/61 have a bidirectional variant?
No, the P4SMA150AHE3/61 is strictly unidirectional, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P4SMA150CA). The P4SMA150AHE3/61 is intended for ground-referenced clamping topologies only; using it in AC-coupled or floating signal paths would result in unintended forward conduction. Always verify polarity during PCB layout.
What package type does the P4SMA150AHE3/61 use, and is it compatible with standard SMT assembly?
The P4SMA150AHE3/61 uses the SMA (DO-214AC) surface-mount package with 2.54 mm lead spacing and matte tin-plated terminations. It meets J-STD-002 solderability standards and is rated MSL Level 1 (peak reflow temperature 260 °C), making it fully compatible with standard lead-free reflow processes without pre-baking. The P4SMA150AHE3/61's low-profile design supports automated placement and high-density board layouts.
