Product details
Overview
P4SMA10CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power capability with a 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P4SMA10CAHE3/61 datasheet, P4SMA10CAHE3/61 pinout, P4SMA10CAHE3/61 application, or P4SMA10CAHE3/61 equivalent, this AEC-Q101-qualified, RoHS-compliant TVS offers verified bidirectional surge suppression, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability PCB designs requiring transient immunity per IEC 61000-4-2/4-4/4-5.
Technical Context
The P4SMA10CAHE3/61 operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients above its breakdown voltage range of 10.5–11.6 V at 1 mA test current. Its glass-passivated junction ensures stable reverse leakage (<50 µA at 8.55 V) and fast response time (<1.0 ns), enabling protection against ESD, lightning-induced surges, and inductive switching spikes.
Thermally, it exhibits a junction-to-ambient thermal resistance of 120 °C/W and supports continuous power dissipation of 3.3 W at 50 °C ambient on infinite heatsink. The device is rated for operation from –65 °C to +150 °C and meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 10.5–11.6 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping threshold under transient stress. |
| VC (Clamping Voltage) | 14.5 V at 27.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress level. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 µs transients without failure; derates to 300 W above 91 V devices (not applicable here). |
| ID (Reverse Leakage) | ≤50 µA at VWM - Minimal standby current draw; preserves signal integrity and battery life in low-power systems. |
| TJ max. | +150 °C - Enables use in under-hood automotive or high-temperature industrial environments without thermal shutdown. |

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤14.5 V, preventing latch-up or damage to 3.3 V/5 V sensor signal conditioning circuits while maintaining signal fidelity. |
Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against field-wiring induced surges and relay contact bounce. IC Role / Device Role / Timing Role: Primary transient suppressor mounted at connector entry point, shunting surge energy to ground before reaching optocoupler or microcontroller input. Use Value: Withstands repetitive 400 W pulses and maintains <50 µA leakage at 8.55 V, ensuring reliable state detection and minimizing false triggers. |
| Consumer Device USB Port Protection | Telecom Line Card Surge Suppression |
Use Scenario: Shielding USB 2.0 data lines (D+/D−) and VBUS in set-top boxes or smart displays from human-body-model ESD events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at USB connector, referenced to local ground. Use Value: Clamps sub-100 ns ESD pulses to <14.5 V without distorting 480 Mbps data signals due to minimal parasitic capacitance and fast response. |
Use Scenario: Protecting Ethernet PHY interfaces and analog line drivers on telecom access equipment exposed to lightning-induced surges on copper pairs. IC Role / Device Role / Timing Role: Secondary-level protector located after gas discharge tube (GDT), absorbing residual energy and limiting let-through voltage. Use Value: Delivers precise 14.5 V clamping at 27.6 A, reducing stress on downstream silicon and meeting GR-1089-CORE Level 4 surge requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Higher package thermal resistance (RθJA = 140 °C/W vs. 120 °C/W); same VWM, VC, and PPPM ratings. | Less efficient heat dissipation in compact layouts; requires larger copper area for equivalent thermal performance. | Select when SMB footprint is already standardized and board space permits additional thermal relief. |
| 1.5KE10CA | Through-hole DO-201 package; higher peak pulse current (32.4 A) but slower response and larger footprint. | Not suitable for high-density SMT designs; limited to legacy or high-surge industrial power supplies. | Choose only for through-hole prototyping or where mechanical robustness outweighs size constraints. |
Compared with SMBJ10CA and 1.5KE10CA, the P4SMA10CAHE3/61 delivers superior thermal performance in a smaller SMA footprint and is uniquely qualified to AEC-Q101 - making it the preferred choice for automotive and space-constrained industrial designs requiring validated reliability.

FAQ
What is the clamping voltage of P4SMA10CAHE3/61 at its rated peak pulse current?
The P4SMA10CAHE3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces downstream of the P4SMA10CAHE3/61.
Is P4SMA10CAHE3/61 suitable for automotive applications?
Yes, P4SMA10CAHE3/61 is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS compliance and automotive-grade reliability. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD verification - making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where P4SMA10CAHE3/61 must operate continuously from –65 °C to +150 °C.
How does the bidirectional design of P4SMA10CAHE3/61 affect its circuit placement?
The bidirectional nature of P4SMA10CAHE3/61 eliminates polarity marking and allows placement across any two nodes subject to differential or AC-coupled transients - such as USB D+/D−, RS-485 lines, or transformer-coupled Ethernet pairs. Unlike unidirectional TVS diodes, P4SMA10CAHE3/61 requires no orientation check during automated placement, simplifying layout and reducing assembly errors in high-volume manufacturing.
What is the maximum steady-state power dissipation rating for P4SMA10CAHE3/61?
The P4SMA10CAHE3/61 has a maximum power dissipation (PD) of 3.3 W when mounted on an infinite heatsink at TA = 50 °C. In real-world PCB layouts, derating applies based on copper pad area and ambient temperature - for example, at 70 °C ambient with 0.2" × 0.2" copper pads per terminal, usable PD drops to approximately 1.8 W. This thermal behavior must be accounted for when sizing P4SMA10CAHE3/61 in continuous overvoltage scenarios.
Does P4SMA10CAHE3/61 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, P4SMA10CAHE3/61 meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means the device can be processed using standard lead-free SMT reflow profiles without baking or dry-pack requirements - significantly reducing handling complexity and cost in production environments deploying P4SMA10CAHE3/61.
