Product details
Overview
P4KE10CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform. Used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the P4KE10CAHE3/54 datasheet, P4KE10CAHE3/54 pinout, P4KE10CAHE3/54 application, or P4KE10CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or forward, in bidirectional mode) voltage exceeds its breakdown threshold (~10.5–11.6 V), it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-41 package supports lead-free soldering per J-STD-002 and JESD 22-B102.
Designed for repetitive transient suppression, it handles 400 W peak pulse power (10/1000 μs) at TA = 25 °C with 0.01 % duty cycle, derating linearly above 25 °C per Fig. 2. Junction temperature range is –55 °C to +175 °C, and it meets AEC-Q101 stress testing for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 10.5–11.6 V at 1 mA - Voltage at which device enters avalanche conduction; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 14.5 V at 27.6 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capacity under standardized 10/1000 μs waveform; validates robustness against lightning or EFT events. |
| ID (Reverse Leakage) | 10 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +175 °C - Enables operation in under-hood automotive or industrial environments without thermal shutdown. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

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 | DO-214AA package; 600 W PPPM; lower RθJA (50 °C/W); higher VC (17.0 V at 34.4 A) | Surface-mount layout; better thermal performance on PCB; less aggressive clamping than P4KE10CAHE3/54 | Select SMBJ10CA for space-constrained SMT designs needing higher surge rating; not pin-compatible due to different package and mounting. |
| 1.5KE10CA | DO-201AD package; 1500 W PPPM; higher VC (17.0 V at 88.2 A); same VWM/VBR range | Higher-energy surge handling; larger footprint; used in primary-side AC protection and industrial power supplies | Choose 1.5KE10CA where >400 W surge immunity is required; requires board redesign due to DO-201AD mechanical dimensions. |
Compared with SMBJ10CA and 1.5KE10CA, the P4KE10CAHE3/54 offers optimal balance of axial-lead serviceability, AEC-Q101 qualification, and precise 14.5 V clamping-making it preferred for automotive and industrial through-hole designs where reliability and standardized DO-41 replacement are critical.

FAQ
What is the clamping voltage of the P4KE10CAHE3/54 and how is it measured?
The P4KE10CAHE3/54 has a maximum clamping voltage (VC) of 14.5 V, measured at a peak pulse current (IPPM) of 27.6 A using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the highest voltage imposed on the protected circuit during surge conditions and is guaranteed across the full operating temperature range.
Is the P4KE10CAHE3/54 suitable for automotive applications?
Yes, the P4KE10CAHE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood and body electronics applications. Its bidirectional architecture, low leakage (≤10 μA), and DO-41 mechanical robustness align with automotive ECU, sensor, and infotainment system protection requirements.
Does the P4KE10CAHE3/54 have polarity markings?
No, the P4KE10CAHE3/54 is a bidirectional TVS diode and carries no cathode band or polarity marking on its DO-41 package. Its electrical characteristics-including breakdown and clamping-are identical in both directions, enabling straightforward placement across AC-coupled or floating signal paths without orientation concerns.
What is the thermal resistance of the P4KE10CAHE3/54 and why does it matter?
The P4KE10CAHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This parameter directly impacts power derating: at elevated ambient temperatures, the device's ability to dissipate surge energy decreases predictably. Engineers use RθJL to calculate safe operating margins in thermally constrained enclosures or high-power-density layouts.
How does the P4KE10CAHE3/54 differ from unidirectional P4KE10A variants?
The P4KE10CAHE3/54 is bidirectional with symmetric clamping in both polarities and no cathode marking, whereas the unidirectional P4KE10A has a cathode band and only clamps in reverse bias. The CA variant is specified for VBR min/max of 10.5–11.6 V (at 1 mA), while P4KE10A shares identical VWM and VC but lacks bidirectional capability-making P4KE10CAHE3/54 essential for AC or differential line protection.
