Product details
Overview
P4SMA75CAHE3/61 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 and power lines. It features a 75 V standoff voltage (VWM), 82.9 V minimum breakdown voltage (VBR), 104 V maximum clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the P4SMA75CAHE3/61 datasheet, P4SMA75CAHE3/61 pinout, P4SMA75CAHE3/61 application, or P4SMA75CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMA (DO-214AC) package compatibility, and thermal resistance (RθJA = 120 °C/W) for board-level surge protection design.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during ESD or lightning-induced transients.
The device meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive applications. With a 150 °C maximum junction temperature and 3.3 W steady-state power dissipation, it supports reliable operation under sustained transient stress when mounted on 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 75 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 82.9–91.6 V at 1 mA - Confirmed minimum/maximum voltage where device enters avalanche conduction; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 104 V at 3.9 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Energy-handling capacity for non-repetitive 10/1000 μs transients; derates to 300 W above 91 V per spec. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area for thermal management at 3.3 W PD. |
| TJ max. | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking - terminals are symmetrical anode/cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient path | Either terminal serves as input/output for clamping; no cathode band marking; enables placement flexibility on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line) when properly laid out with 5 mm² copper pads. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics where long-term reliability under thermal cycling and humidity is mandatory. |
| Glass passivated junction | Ensures stable VBR over lifetime and reduces parameter drift due to moisture or contamination exposure. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without pre-baking; eliminates manufacturing yield risk. |
| Low clamping ratio (VC/VBR ≈ 1.25) | Minimizes overvoltage overshoot during fast transients, improving protection margin for 3.3 V or 5 V logic interfaces. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Higher PPPM (600 W), larger SMB (DO-214AA) package, RθJA = 85 °C/W | Better suited for higher-energy surges; requires larger PCB footprint and different pad layout | Select when >400 W surge handling is required and board space allows SMB package |
| 1.5KE75CA | Through-hole DO-201 package, 1500 W PPPM, higher capacitance (>100 pF) | Not suitable for high-speed data lines; intended for AC mains or bulk power rail protection | Choose only for legacy through-hole designs or where higher peak power outweighs layout constraints |
Compared with SMBJ75CA and 1.5KE75CA, P4SMA75CAHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and 400 W surge rating - making it preferred for space-constrained automotive and industrial SMT designs requiring validated reliability.

FAQ
What does the "CA" suffix indicate in P4SMA75CAHE3/61?
The "CA" suffix in P4SMA75CAHE3/61 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with no cathode marking and identical electrical characteristics in either direction. This is essential for protecting AC-coupled or differential signal lines where polarity reversal may occur.
Is P4SMA75CAHE3/61 suitable for IEC 61000-4-5 surge testing?
Yes, P4SMA75CAHE3/61 can support IEC 61000-4-5 Level 4 (4 kV line-to-line) when implemented with recommended 5.0 mm × 5.0 mm copper pads per terminal and proper PCB layout. Its 400 W PPPM rating and 104 V clamping voltage provide sufficient margin for this standard, though system-level testing is required for full compliance.
How does the HE3 suffix affect P4SMA75CAHE3/61's qualifications?
The HE3 suffix in P4SMA75CAHE3/61 indicates RoHS-compliant construction and AEC-Q101 qualification - confirming that the device has passed automotive-grade stress tests including temperature cycling, high-temperature reverse bias, and ESD robustness. This makes it suitable for under-hood and safety-critical automotive applications.
What is the maximum operating temperature for P4SMA75CAHE3/61?
The maximum junction temperature (TJ max.) for P4SMA75CAHE3/61 is +150 °C, and its storage temperature range extends from –65 °C to +150 °C. This rating enables use in engine control units, industrial motor drives, and other high-ambient-temperature environments when thermal design accounts for RθJA = 120 °C/W.
Can P4SMA75CAHE3/61 replace unidirectional P4SMA75AHE3/61 in existing designs?
No - P4SMA75CAHE3/61 is bidirectional and lacks polarity marking, whereas P4SMA75AHE3/61 is unidirectional with a cathode band. Substitution requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating references, while unidirectional parts are needed for DC-biased rails where reverse conduction must be blocked.
