Product details
Overview
P6KE20CAHE3/54 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), 20 V breakdown voltage (VBR min/max = 19.0–21.0 V at 1.0 mA), and clamps to ≤27.7 V at 21.7 A peak pulse current. Used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE20CAHE3/54 datasheet, P6KE20CAHE3/54 pinout, P6KE20CAHE3/54 application, or P6KE20CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating under transient stress.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 17.1 V stand-off), while the 20 °C/W junction-to-lead thermal resistance supports reliable energy dissipation during repetitive surges.
The P6KE20CAHE3/54 is rated for 600 W peak pulse power per 10/1000 μs waveform at 0.01% duty cycle, with clamping voltage tightly specified at 27.7 V (max) at 21.7 A - critical for safeguarding downstream MOSFET gates or microcontroller I/O pins against lightning-induced or inductive-switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.0 V / 21.0 V at 1.0 mA - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 17.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤27.7 V at 21.7 A - ensures protected circuit sees no more than 27.7 V during worst-case 600 W transient |
| PPPM | 600 W (10/1000 μs) - delivers industry-standard surge immunity for IEC 61000-4-5 Level 3/4 compliance |
| TJ max | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| Package | DO-15 (DO-204AC) - through-hole mount compatible with legacy PCB designs and automated insertion |

Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; bidirectional construction has no polarity marking - both terminals are electrically symmetric and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Either terminal conducts during overvoltage in either polarity - no orientation required during placement |
| Leads (both) | Thermal and electrical interface | Provide mechanical mounting and conduct surge energy to PCB copper; RθJL = 20 °C/W enables effective heat transfer to board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20CA | Same VBR range (19.0–21.0 V) and bidirectional function, but SMC (DO-214AB) surface-mount package - 600 W rating, lower RθJA (50 °C/W vs. 75 °C/W) | Requires PCB redesign for SMT assembly; better suited for space-constrained, high-density layouts | Select SMBJ20CA when migrating to surface-mount manufacturing or improving thermal performance on thermally optimized boards |
| 1.5KE20CA | Same DO-15 package and bidirectional configuration, but higher 1500 W peak pulse power (10/1000 μs); VBR identical (19.0–21.0 V), VC = 32.4 V at 46.3 A | Higher clamping voltage reduces margin for low-voltage ICs; preferred where larger surge margins are needed | Choose 1.5KE20CA when protecting circuits subject to repeated high-energy transients exceeding 600 W capability |
Compared with SMBJ20CA and 1.5KE20CA, the P6KE20CAHE3/54 offers AEC-Q101 qualification and optimal balance of through-hole manufacturability, 600 W surge rating, and 27.7 V clamping - making it ideal for cost-sensitive, automotive-qualified, or legacy through-hole designs.

FAQ
What is the breakdown voltage tolerance for P6KE20CAHE3/54?
The P6KE20CAHE3/54 has a minimum breakdown voltage of 19.0 V and maximum of 21.0 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 20 V rating. This tight VBR window ensures consistent clamping behavior across production lots and temperature ranges, critical for predictable circuit protection design using the P6KE20CAHE3/54.
Is P6KE20CAHE3/54 suitable for automotive applications?
Yes, the P6KE20CAHE3/54 carries the HE3 suffix indicating AEC-Q101 qualification - verified for automotive-grade reliability including temperature cycling, humidity resistance, and mechanical shock. Its 175 °C maximum junction temperature and bidirectional clamping make it appropriate for under-hood sensor protection and body electronics where the P6KE20CAHE3/54 must survive harsh environmental stress.
What does the "CA" suffix mean in P6KE20CAHE3/54?
The "CA" suffix in P6KE20CAHE3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6KE20A), the P6KE20CAHE3/54 has no cathode marking and functions identically regardless of terminal orientation, simplifying layout for AC-coupled or floating signal paths.
How does P6KE20CAHE3/54 compare to P6KE20A in terms of application use?
The P6KE20CAHE3/54 differs from P6KE20A solely in polarity: P6KE20A is unidirectional (cathode-marked, forward-biased conduction), while P6KE20CAHE3/54 is bidirectional (no marking, symmetrical clamping). Use P6KE20CAHE3/54 for differential lines, AC signals, or any application where polarity reversal or unknown signal direction exists - the P6KE20CAHE3/54 eliminates orientation errors during assembly.
What is the maximum clamping voltage of P6KE20CAHE3/54 at rated surge current?
The P6KE20CAHE3/54 clamps to a maximum of 27.7 V at its rated peak pulse current of 21.7 A (10/1000 μs waveform). This value is guaranteed across temperature and production lot, ensuring downstream components like microcontrollers or transceivers remain within safe absolute maximum ratings during surge events - a key specification confirmed in the official Vishay datasheet for P6KE20CAHE3/54.
