Product details
Overview
P4KE100CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 100 V standoff voltage (VWM), 114–126 V breakdown range (VBR), 137 V maximum clamping voltage at 2.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE100CAHE3/54 datasheet, P4KE100CAHE3/54 pinout, P4KE100CAHE3/54 application, or P4KE100CAHE3/54 equivalent, this AEC-Q101 qualified TVS provides verified bidirectional surge protection for automotive sensor interfaces, industrial I/O lines, telecom line cards, and DC power rail inputs where fast response (<1 ns), low clamping ratio, and robust 175 °C junction operation are required.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling suppression of both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
The P4KE100CAHE3/54 is rated for 400 W peak pulse power (10/1000 μs), 1.5 W steady-state power dissipation, and supports operating junction temperatures from –55 °C to +175 °C - making it suitable for under-hood automotive and high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V/24 V/48 V systems. |
| VBR min/max | 114 V / 126 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 137 V at 2.9 A - Clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 400 W - Peak surge energy handling capability; sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3. |
| TJ max | +175 °C - Maximum junction temperature; enables use in engine control units and motor drive enclosures without derating. |
| ID @ VWM | 1.0 μA - Reverse leakage at rated standoff; negligible loading on high-impedance sensor or communication lines. |
| Package | DO-41 (DO-204AL) - Industry-standard axial-leaded package with UL 94 V-0 epoxy; compatible with through-hole assembly and manual repair. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional operation; lead length ≥9.5 mm for thermal derating compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 | Surface-mount SMB package; same 100 V VWM but lower 600 W PPPM rating; 100 pF typical junction capacitance vs. ~50 pF for P4KE100CAHE3/54. | Preferred for high-density PCBs where space is constrained; less suitable for high-temperature through-hole assemblies requiring mechanical robustness. | Select SMBJ100CA when board real estate is limited and reflow compatibility is required; verify thermal relief pad design for 1.5 W steady-state dissipation. |
| 1.5KE100CA | Higher 1500 W peak pulse power; larger DO-201AD package; identical VWM/VBR/VC specs; same AEC-Q101 qualification. | Better suited for severe surge environments (e.g., railway signaling, solar string inverters); requires larger PCB cutout and higher assembly torque. | Choose 1.5KE100CA when system-level testing reveals marginal margin with 400 W rating; retains identical electrical behavior with enhanced energy handling. |
Compared with SMBJ100CA and 1.5KE100CA, the P4KE100CAHE3/54 delivers optimal balance of proven automotive reliability, axial-leaded mechanical stability, and cost-effective 400 W surge immunity - ideal for volume production of industrial and automotive modules where DO-41 compatibility and AEC-Q101 traceability are mandatory.

FAQ
What is the clamping voltage of the P4KE100CAHE3/54 under a 10/1000 μs surge?
The P4KE100CAHE3/54 has a maximum clamping voltage (VC) of 137 V at 2.9 A peak pulse current (IPPM) for a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the P4KE100CAHE3/54 suitable for automotive applications?
Yes, the P4KE100CAHE3/54 is AEC-Q101 qualified (HE3 suffix), confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. It operates reliably from –55 °C to +175 °C and meets stringent stress-test requirements for humidity, temperature cycling, and surge endurance.
How does the bidirectional configuration of the P4KE100CAHE3/54 affect its circuit placement?
The P4KE100CAHE3/54 has no polarity marking and functions identically in both directions, allowing flexible placement across any two-node interface - such as differential signal lines, AC power inputs, or ungrounded DC rails. This eliminates orientation errors during assembly and simplifies layout for symmetric protection schemes.
What is the thermal resistance of the P4KE100CAHE3/54, and how does it impact PCB layout?
The P4KE100CAHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. To maintain safe operation at 1.5 W steady-state dissipation, PCB traces connected to both leads must provide adequate copper area and thermal relief - minimum 2.5 mm width and ≥10 mm length recommended for lead-to-copper heat transfer.
Does the P4KE100CAHE3/54 require additional series impedance for effective protection?
No, the P4KE100CAHE3/54 functions as a standalone shunt protector and does not require series resistors or inductors for basic transient suppression. Its low dynamic impedance and sub-nanosecond response enable direct parallel connection to protected nodes - though coordinated staging with GDTs or PTCs may be used for multi-level protection in high-energy threat environments.
