Product details
Overview
P6KE110CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 110 V breakdown voltage (min 105 V, max 116 V at 1 mA), 152 V maximum clamping voltage at 3.9 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE110CAHE3/54 datasheet, P6KE110CAHE3/54 pinout, P6KE110CAHE3/54 application, or P6KE110CAHE3/54 equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O modules, and telecom line drivers where bidirectional surge immunity and low clamping ratio are critical.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, with no polarity marking on the DO-15 body. Its glass-passivated junction enables fast response (<1 ns) and stable clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and TJmax = +175 °C, supporting operation in high-temperature environments such as engine control units and power supply front-ends without derating below 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1 mA - defines reliable conduction onset across manufacturing lot and temperature range |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 152 V at 3.9 A - clamping voltage during worst-case 600 W transient, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, enabling IEC 61000-4-5 Level 4 compliance |
| IPPM | 3.9 A - peak pulse current corresponding to VC, used to size series impedance for energy absorption |
| TJmax | +175 °C - junction temperature limit allowing placement near heat sources in automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VBR (105–116 V), lower PPPM (600 W → 600 W), but SMB package (smaller footprint, higher thermal resistance RθJA = 110 °C/W vs. 75 °C/W) | Preferred for space-constrained PCBs; less suitable for sustained surge duty cycles above 25 °C ambient | Select SMBJ110CA when board area is critical and thermal management is assured via copper pour or airflow |
| 1.5KE110CA | Same VBR and VC, identical DO-15 package, but higher PPPM (1500 W) and larger junction area (higher IPPM = 9.4 A) | Better suited for high-energy transients (e.g., ISO 7637-2 pulse 5b); overqualified for typical IEC 61000-4-5 use cases | Choose 1.5KE110CA only when legacy designs require backward compatibility or surge test margins exceed 600 W |
Compared with SMBJ110CA and 1.5KE110CA, P6KE110CAHE3/54 delivers optimal balance of AEC-Q101 qualification, DO-15 mechanical robustness, and 600 W surge capacity-making it the preferred choice for cost-sensitive automotive and industrial designs requiring proven reliability without overengineering.

FAQ
What is the clamping voltage of P6KE110CAHE3/54 under maximum rated surge current?
The P6KE110CAHE3/54 has a maximum clamping voltage (VC) of 152 V when subjected to its peak pulse current (IPPM) of 3.9 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and ensures downstream circuitry remains below destructive voltage thresholds during standardized surge events. The P6KE110CAHE3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE110CAHE3/54 suitable for automotive applications?
Yes, P6KE110CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its DO-15 package, glass-passivated junction, and operation from –55 °C to +175 °C junction temperature meet stringent automotive environmental requirements. The P6KE110CAHE3/54 HE3 suffix confirms AEC-Q101 compliance per Vishay documentation.
How does the bidirectional design of P6KE110CAHE3/54 affect its circuit implementation?
The bidirectional design of P6KE110CAHE3/54 eliminates polarity concerns-both terminals are functionally identical, so no cathode band marking exists. It is installed across protected lines (e.g., signal-to-ground or differential pair) without orientation constraints, simplifying layout and assembly. This symmetry ensures equal clamping for positive and negative transients, making P6KE110CAHE3/54 ideal for AC-coupled or floating interfaces.
What is the maximum steady-state power dissipation of P6KE110CAHE3/54?
P6KE110CAHE3/54 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. Under normal operating conditions with no surge, its reverse leakage current is ≤1 μA at VWM = 94.0 V, resulting in negligible static power draw. The P6KE110CAHE3/54 is not intended for continuous conduction but for transient-only protection.
Does P6KE110CAHE3/54 require a series impedance for optimal protection?
Yes, P6KE110CAHE3/54 should be used with a series impedance (e.g., resistor or ferrite bead) to limit peak current during clamping and coordinate with upstream protectors like MOVs. Without series impedance, the low dynamic impedance of P6KE110CAHE3/54 may draw excessive current during long-duration transients, risking thermal runaway. Proper coordination ensures the P6KE110CAHE3/54 handles fast edges while upstream devices absorb bulk energy.
