Product details
Overview
P6KE150CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal lines. It features a 150 V breakdown voltage (VBR min/max = 143 V / 158 V), 128 V standoff voltage (VWM), 207 A peak pulse current (IPPM), 207 V clamping voltage (VC) at IPPM, and 600 W peak pulse power (10/1000 μs waveform). It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor interfaces in automotive power systems.
For engineers reviewing the P6KE150CAHE3/54 datasheet, P6KE150CAHE3/54 pinout, P6KE150CAHE3/54 application, or P6KE150CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 thermal resistance (RθJL = 20 °C/W), low leakage (<1.0 μA at VWM), AEC-Q101 qualification, and compatibility with 100 A surge current (IFSM) in automotive front-end protection circuits.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR. Its bidirectional symmetry enables use on AC lines or differential signal pairs without polarity concerns.
The junction is glass passivated for stable avalanche characteristics and long-term reliability. Thermal design relies on lead-to-ambient path (RθJA = 75 °C/W) and lead-to-case conduction (RθJL = 20 °C/W), supporting operation up to TJ = +175 °C with derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines guaranteed avalanche onset range at 1 mA test current; ensures consistent clamping threshold across production lot |
| VWM | 128 V - maximum continuous reverse operating voltage; must exceed system's peak steady-state voltage to prevent leakage-induced heating |
| VC @ IPPM | 207 V - clamped voltage during 600 W transient (10/1000 μs); determines maximum stress imposed on protected downstream components |
| IPPM | 207 A - peak surge current survivable per pulse; sets minimum upstream fuse rating and PCB trace width requirements |
| PPPM | 600 W - standardized transient energy handling (10/1000 μs); enables direct comparison with IEC 61000-4-5 Level 4 surge immunity requirements |
| ID @ VWM | <1.0 μA - reverse leakage at standoff voltage; critical for low-power sensor bias networks where leakage could shift reference points |
| TJ max. | +175 °C - maximum junction temperature; supports under-hood automotive placement with appropriate board-level thermal relief |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads. Dimensions: 3.3–3.5 mm diameter × 6.15–6.55 mm body length; lead length ≥25.4 mm. RoHS compliant, AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward conduction mode | Not functional in bidirectional TVS operation; symmetric terminals enable mounting without orientation check |
| Cathode (unmarked end) | Current exit point in forward conduction mode | Identical electrical behavior to anode; no polarity marking required per datasheet note for CA types |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, repeatable avalanche characteristics over 1000+ surge events and >15-year field life |
| 600 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity for industrial and automotive power inputs without external series impedance |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive under-hood applications including engine control units and body electronics modules |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a), improving protection margin |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed automotive or industrial enclosures during catastrophic failure modes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | DO-214AA package; lower RθJA (50 °C/W); same VBR/VC specs but 600 W rating at 10/1000 μs | Better thermal performance in surface-mount layouts; requires PCB rework for through-hole replacement | Select SMBJ150CA when board space is constrained and SMT assembly is available |
| 1.5KE150CA | Higher 1500 W peak power rating; larger DO-201AD package; identical VBR/VC and bidirectional structure | Supports higher-energy transients (e.g., IEC 61000-4-5 Level 5); requires larger footprint and higher mounting torque | Choose 1.5KE150CA where legacy designs mandate higher surge margin or mechanical robustness is prioritized |
Compared with SMBJ150CA and 1.5KE150CA, P6KE150CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-15 through-hole manufacturability, and 600 W surge handling-making it preferred for cost-sensitive, high-volume automotive and industrial through-hole assemblies where thermal budget allows RθJA = 75 °C/W.

FAQ
What is the clamping voltage of P6KE150CAHE3/54 at its rated peak pulse current?
The clamping voltage (VC) of P6KE150CAHE3/54 is 207 V when subjected to its maximum peak pulse current (IPPM) of 207 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE150CAHE3/54 maintains this clamping performance across its qualified temperature range (−55 °C to +175 °C) with minimal drift.
Is P6KE150CAHE3/54 suitable for automotive under-hood applications?
Yes, P6KE150CAHE3/54 is AEC-Q101 qualified (denoted by HE3 suffix) and rated for junction temperatures up to +175 °C, making it suitable for under-hood automotive environments such as engine control units and body control modules. Its DO-15 package provides mechanical robustness against vibration, and its glass-passivated junction ensures long-term stability under thermal cycling. The P6KE150CAHE3/54 meets requirements for load dump (ISO 16750-2) and conducted transients (ISO 7637-2) when properly mounted with adequate copper pour.
How does the bidirectional configuration of P6KE150CAHE3/54 affect its usage compared to unidirectional variants?
The CA suffix in P6KE150CAHE3/54 indicates bidirectional construction, meaning it provides symmetrical clamping for both positive and negative voltage transients without polarity sensitivity. Unlike unidirectional P6KE150A, which requires correct cathode orientation, the P6KE150CAHE3/54 can be installed in either direction-ideal for AC lines, differential buses (e.g., RS-485), or floating grounds. Its VBR and VC values apply identically in both directions, simplifying layout and reducing BOM complexity.
What is the maximum leakage current of P6KE150CAHE3/54 at its standoff voltage?
The maximum reverse leakage current (ID) of P6KE150CAHE3/54 is 1.0 μA at its standoff voltage (VWM) of 128 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss and avoids interference in high-impedance sensing circuits such as thermistor or potentiometer interfaces. The P6KE150CAHE3/54 maintains leakage below 5 μA even at elevated temperatures up to +125 °C, as confirmed by Vishay's derating curves in document 88369.
Can P6KE150CAHE3/54 replace P6KE150A in an existing design?
No-P6KE150CAHE3/54 cannot directly replace unidirectional P6KE150A without circuit review. While both share identical VBR, VWM, and VC ratings, the P6KE150A is unidirectional and requires correct polarity orientation, whereas the P6KE150CAHE3/54 is bidirectional with no polarity marking. Substituting P6KE150CAHE3/54 may alter grounding schemes or fail-safe behavior in DC-coupled circuits. Verify system-level surge path symmetry before using P6KE150CAHE3/54 as a drop-in alternative.
