Product details
Overview
P4SMA100AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V standoff voltage (VWM), 105 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 2.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for automotive-grade ESD and surge protection in sensor interfaces and power rails.
For engineers reviewing the P4SMA100AHE3/61 datasheet, P4SMA100AHE3/61 pinout, P4SMA100AHE3/61 application, or P4SMA100AHE3/61 equivalent, key selection criteria include its AEC-Q101 qualification, SMA (DO-214AC) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 120 °C/W) for board-level thermal design validation.
Technical Context
The P4SMA100AHE3/61 operates as a clamping-type TVS diode with avalanche breakdown behavior, triggered when reverse voltage exceeds its 95–105 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable leakage performance (<1 µA at 85.5 V) and fast response time (<1 ns) to transient events.
It is rated for 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports continuous power dissipation of 3.3 W on infinite heatsink at 50 °C, and maintains operation across -65 °C to +150 °C junction temperature range - enabling use in under-hood automotive and industrial environments where thermal derating must be modeled per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 137 V at IPPM = 2.2 A (10/1000 µs) - Peak voltage seen by protected circuit; critical for IC survivability margin. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standard lightning/surge waveform; derated above 25 °C. |
| IR (Reverse Leakage) | <1 µA at 85.5 V - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | +150 °C - Enables placement near heat sources (e.g., power MOSFETs, DC-DC converters) without thermal shutdown. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress-test requirements including HTRB, HTGB, and temperature cycling. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability and J-STD-002 solderability standards. Cathode indicated by band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients in bidirectional configs (not applicable here). |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail or CAN_H); avalanches into conduction when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensors. |
| 400 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges without degradation. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage under humidity, temperature cycling, and mechanical stress. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT assembly processes without moisture sensitivity concerns. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD >15 kV contact discharge). |
Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52 (Vishay) | Same VWM/VBR/VC specs but SMB (DO-214AA) package - 2.5 mm wider, higher RθJA (100 °C/W), 600 W PPPM rating. | Better suited for higher-power industrial designs where PCB space allows larger footprint and thermal relief. | Select when 600 W surge margin is required and layout accommodates 4.6 mm × 3.6 mm vs. SMA's 4.3 mm × 2.6 mm. |
| 1.5KE100A (ON Semiconductor) | Through-hole DO-201 package; identical 100 V VWM, but higher VC (148 V), lower IFSM (45 A), no AEC-Q101 qualification. | Limited to commercial/industrial prototyping; not approved for automotive production due to missing qualification. | Use only for cost-sensitive non-automotive applications where through-hole assembly is preferred and 11 V higher clamping is acceptable. |
Compared with SMBJ100A-E3/52 and 1.5KE100A, the P4SMA100AHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and verified 137 V clamping - making it the preferred choice for space-constrained automotive modules requiring zero-layout rework for qualification.

FAQ
What is the clamping voltage of P4SMA100AHE3/61 at its rated peak pulse current?
The P4SMA100AHE3/61 has a maximum clamping voltage (VC) of 137 V when subjected to its specified peak pulse current of 2.2 A using the 10/1000 µs waveform. This value is measured under standardized test conditions per JEDEC and is guaranteed across the full operating temperature range, ensuring consistent protection behavior in automotive and industrial deployments where voltage margin is critical.
Is P4SMA100AHE3/61 qualified for automotive applications?
Yes, P4SMA100AHE3/61 is explicitly AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics.
What does the "HE3" suffix indicate in P4SMA100AHE3/61?
The "HE3" suffix in P4SMA100AHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability standards. It distinguishes this variant from commercial-grade "E3" parts and halogen-free "HM3" versions, confirming its intended use in automotive production environments requiring both environmental compliance and reliability certification.
Can P4SMA100AHE3/61 be used in bidirectional configurations?
No, P4SMA100AHE3/61 is a unidirectional TVS diode, as indicated by the "A" suffix (vs. "CA" for bidirectional). Its cathode band marking and asymmetric IV curve mean it conducts only in reverse bias - for bidirectional protection, Vishay specifies parts like P4SMA100CAHE3/61, which exhibit symmetrical clamping in both polarities.
What is the thermal resistance junction-to-ambient for P4SMA100AHE3/61?
The P4SMA100AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended copper pad layout (0.2" x 0.2"). This value assumes no additional heatsinking and must be factored into thermal derating calculations - especially in automotive applications where ambient temperatures exceed 85 °C and power dissipation approaches 3.3 W.
