Product details
Overview
P4SMA100CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 100 V standoff voltage (VWM), 114 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the P4SMA100CAHE3/61 datasheet, P4SMA100CAHE3/61 pinout, P4SMA100CAHE3/61 application, or P4SMA100CAHE3/61 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 transient immunity design.
Technical Context
The P4SMA100CAHE3/61 operates as a bidirectional avalanche diode, providing symmetrical clamping in both polarities without polarity marking. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL Level 1 (peak reflow 260 °C), it supports automated SMT assembly. The device delivers 400 W peak pulse power up to 91 V and 300 W above 91 V, with derating per Fig. 2 for elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 114–126 V at 1 mA - Minimum and maximum voltage at which avalanche conduction begins; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 137 V at IPPM = 2.2 A - Maximum voltage seen across terminals during 10/1000 µs transient; determines protected circuit's stress level. |
| PPPM (Peak Pulse Power) | 400 W (≤91 V), 300 W (>91 V) - Surge energy handling capacity under standard waveform; sets robustness against repetitive transients. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature rating; defines thermal design limits for PCB copper pad layout and power cycling. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; guides heatsinking requirements when mounted on 0.2" × 0.2" copper pads. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetric; device functions identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Accepts reverse surge current during negative-going transients; connects to protected line or ground reference. |
| Cathode | Transient current entry (positive polarity) | Accepts reverse surge current during positive-going transients; connects to protected line or ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and ADAS sensor modules. |
| Glass passivated junction | Ensures stable avalanche characteristics and long-term parameter consistency across thermal and humidity stress conditions. |
| MSL Level 1 (260 °C peak) | Enables single-reflow SMT assembly without moisture sensitivity concerns - eliminates bake-out requirement pre-assembly. |
| 400 W peak pulse power (10/1000 µs) | Provides robust protection against IEC 61000-4-5 Level 3 (1 kV/2 Ω) surges on industrial control inputs and telecom ports. |
| Low clamping ratio (VC/VBR ≈ 1.20) | Minimizes overvoltage exposure to downstream ICs - critical for safeguarding 3.3 V or 5 V logic interfaces with tight voltage margins. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential signal pair or supply rail to shunt transient energy to ground.

Use Value: Prevents false triggering and latch-up in optocoupler input stages without adding series impedance or propagation delay. |
| Telecom Line Interface | Consumer Power Adapter EMI Filtering |
Use Scenario: Shielding Ethernet PHY interface pins and RS-485 transceivers from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Differential-mode TVS across twisted-pair lines to suppress common-mode transients before they reach isolation barriers. Use Value: Achieves >20 kV ESD (IEC 61000-4-2) and 1 kV surge (IEC 61000-4-5) immunity without degrading 100 Mbps signal integrity. |
Use Scenario: Suppressing fast-rising switching noise and line transients at AC-DC adapter secondary-side outputs feeding USB-C PD controllers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on 5–20 V output rails to prevent overvoltage damage during hot-plug or fault recovery. Use Value: Enables compact layout with <10 pF junction capacitance (typ.) - avoids resonance with output filter inductors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Higher package thermal mass (SMB/DO-214AA); RθJA = 85 °C/W; same VWM/VC ratings but 600 W PPPM rating. | Better suited for higher-duty-cycle surge environments due to lower thermal resistance and higher peak power. | Select SMBJ100CA when board space allows larger footprint and thermal performance outweighs size constraints. |
| 1.5KE100CA | Through-hole (DO-201AE) package; 1500 W PPPM; higher junction capacitance (~1000 pF); no AEC-Q101 qualification. | Used in legacy industrial power supplies where manual assembly and higher surge margin are prioritized over SMT compatibility. | Choose 1.5KE100CA only for non-automotive, non-SMT designs requiring >400 W surge handling and cost-sensitive through-hole manufacturing. |
Compared with SMBJ100CA and 1.5KE100CA, the P4SMA100CAHE3/61 offers optimal balance of AEC-Q101 compliance, SMT scalability, and compact DO-214AC footprint - making it preferred for new automotive and space-constrained industrial designs requiring validated reliability and automated assembly.

FAQ
What is the clamping voltage of the P4SMA100CAHE3/61 under a 10/1000 µs surge?
The P4SMA100CAHE3/61 has a maximum clamping voltage (VC) of 137 V at a peak pulse current (IPPM) of 2.2 A with a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet (Document Number: 88367) and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the P4SMA100CAHE3/61 suitable for automotive applications?
Yes, the P4SMA100CAHE3/61 is AEC-Q101 qualified and carries the HE3 suffix indicating automotive-grade qualification. It meets stress test requirements for temperature cycling, high-temperature reverse bias, and ESD, making it appropriate for use in engine control units, ADAS sensors, and body electronics where reliability under harsh conditions is mandatory.
What does the "CA" suffix mean in P4SMA100CAHE3/61?
The "CA" suffix in P4SMA100CAHE3/61 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4SMA100A), it has no cathode band marking and functions identically regardless of terminal orientation.
What is the thermal resistance of the P4SMA100CAHE3/61, and how does it affect layout?
The P4SMA100CAHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal PCB copper; increasing pad area or adding thermal vias reduces effective RθJA and improves sustained surge handling capability.
Does the P4SMA100CAHE3/61 require polarity-aware placement on the PCB?
No, the P4SMA100CAHE3/61 is a bidirectional TVS and has no polarity marking. Its symmetrical construction means either terminal can connect to the protected line or ground reference - eliminating orientation errors during automated placement and simplifying schematic symbol usage.
