Product details
Overview
P6KE110-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 105 V minimum breakdown voltage (VBR), 94.0 V standoff voltage (VWM), 152 V maximum clamping voltage at 3.9 A peak pulse current (VC @ IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supply inputs.
For engineers reviewing the P6KE110-E3/73 datasheet, P6KE110-E3/73 pinout, P6KE110-E3/73 application, or P6KE110-E3/73 equivalent, this device is selected for robust surge immunity in 24 V–48 V systems where fast clamping (<1 ns response), low leakage (<1.0 μA at VWM), and AEC-Q101 qualification are required for reliability-critical transient suppression.
Technical Context
The P6KE110-E3/73 operates as a silicon avalanche diode with glass-passivated junction, optimized for unidirectional clamping in series with the protected line. Its thermal resistance (RθJL = 20 °C/W) enables effective heat dissipation through leads under repetitive surge conditions, while its 175 °C maximum junction temperature supports operation in under-hood automotive environments.
Clamping behavior is defined by two key points: VBR measured at 1.0 mA test current (105–116 V range), and VC = 152 V at IPPM = 3.9 A (10/1000 μs), yielding a dynamic impedance of ~39 Ω. The device exhibits +0.107 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 94.0 V - Maximum continuous DC or RMS voltage before significant leakage; sets upper limit for normal operating rail voltage. |
| VBR (Breakdown Voltage) | 105–116 V at 1.0 mA - Avalanche onset range; ensures reliable conduction only during overvoltage events above system nominal. |
| VC @ IPPM | 152 V at 3.9 A (10/1000 μs) - Clamped voltage seen by downstream circuitry; defines worst-case stress on protected ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustains single 10/1000 μs transients without failure; derates linearly above 25 °C ambient per Fig. 2. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - Withstands high-energy inductive switch-off surges without bond-wire fusing. |
| Leakage Current (ID) | <1.0 μA at 94.0 V - Negligible loading on 24 V/48 V supply rails during normal operation. |
| Junction Temp Range | –55 to +175 °C - Validated for under-hood automotive, industrial motor drive, and outdoor telecom enclosures. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with matte tin-plated leads. Cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end opposite) | Current entry during forward conduction | Connected to ground or low-side return path in unidirectional configuration; not used for clamping. |
| Cathode (banded end) | Transient current sink during reverse avalanche | Connected to protected line (e.g., 24 V rail); conducts surge current to ground when VLINE exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under thermal cycling. |
| 600 W peak pulse power (10/1000 μs) | Handles ISO 7637-2 Pulse 1/2a/5a transients in 24 V automotive systems without degradation. |
| AEC-Q101 qualified (E3 suffix) | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients, protecting sensitive gate drivers and microcontrollers. |
| RoHS-compliant, JESD201 Class 1A whisker tested | Ensures solder joint integrity in lead-free reflow processes and long-term field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A | Same VWM (94 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB redesign for SMD layout; unsuitable for through-hole legacy designs or high-temperature lead soldering. | Select when board space is constrained and reflow assembly is used; verify thermal pad design for 400 W pulse handling. |
| 1.5KE110A | Same VWM/VBR specs, identical DO-204AC package, but rated for 1500 W PPPM (10/1000 μs) | Higher surge margin for infrequent extreme transients (e.g., direct lightning coupling); larger junction capacitance may affect high-speed signal lines. | Choose when system-level testing reveals marginal margin with 600 W rating; confirm mechanical fit and thermal mass compatibility. |
Compared with SMAJ110A and 1.5KE110A, the P6KE110-E3/73 delivers optimal balance of proven 600 W surge capability, through-hole manufacturability, AEC-Q101 qualification, and cost efficiency for volume automotive and industrial power rail protection - without requiring PCB redesign or over-spec'ed power handling.

FAQ
What is the maximum clamping voltage of the P6KE110-E3/73 under standard test conditions?
The P6KE110-E3/73 has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 μs peak pulse current of 3.9 A. This value is measured per JEDEC standards and represents the worst-case voltage imposed on protected circuitry during a defined transient event - critical for verifying voltage margins of downstream ICs like microcontrollers or gate drivers in the P6KE110-E3/73 application circuit.
Is the P6KE110-E3/73 suitable for automotive applications?
Yes, the P6KE110-E3/73 carries the E3 suffix indicating RoHS compliance and AEC-Q101 qualification per Vishay documentation. It meets stress test requirements for temperature cycling, high-temperature operating life, and ESD robustness, making it appropriate for under-hood and chassis-mounted automotive subsystems such as body control modules and engine control units using the P6KE110-E3/73 for power rail protection.
How does the P6KE110-E3/73 differ from bi-directional TVS diodes like P6KE110CA?
The P6KE110-E3/73 is unidirectional and features a cathode band for polarity identification, conducting only in reverse avalanche mode - ideal for DC rail protection with defined ground reference. In contrast, P6KE110CA is bi-directional, symmetric in both polarities, and lacks marking; it suits AC-coupled or floating signal lines. The P6KE110-E3/73 cannot replace P6KE110CA in AC applications without circuit redesign.
What is the thermal resistance specification for the P6KE110-E3/73?
The P6KE110-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard mounting conditions with 0.375" lead length. This parameter governs temperature rise during repetitive surge events and informs heatsinking decisions - for example, limiting duty cycle above 25 °C ambient per the derating curve in Figure 2 of the P6KE110-E3/73 datasheet.
Can the P6KE110-E3/73 be used in place of the older P6KE110A part?
Yes, the P6KE110-E3/73 is a direct replacement for P6KE110A, sharing identical electrical specifications, DO-204AC package, and performance characteristics. The "E3/73" suffix denotes RoHS-compliant, commercial-grade packaging with matte tin plating and JESD201 Class 1A whisker resistance - no changes to schematic, layout, or thermal design are needed when migrating from P6KE110A to P6KE110-E3/73.
