Product details
Overview
P6KE56CAHE3/54 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), 53.2–58.8 V breakdown voltage at 1 mA, and clamps to ≤77.0 V at 7.8 A peak pulse current. Used in automotive sensor interfaces and industrial I/O protection where bidirectional surge immunity is required.
For engineers reviewing the P6KE56CAHE3/54 datasheet, P6KE56CAHE3/54 pinout, P6KE56CAHE3/54 application, or P6KE56CAHE3/54 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-clamped crowbar during ESD or lightning-induced surges, leveraging avalanche breakdown in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for repeatable clamping performance across thermal cycles.
The P6KE56CAHE3/54 is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 0.103 %/°C temperature coefficient of VBR, enabling predictable voltage margining in automotive under-hood environments up to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 53.2–58.8 V at 1 mA - defines minimum clamping threshold before conduction begins in either polarity |
| Stand-off Voltage VWM | 47.8 V - maximum continuous reverse voltage without significant leakage (<1 μA) |
| Clamping Voltage VC | ≤77.0 V at 7.8 A (10/1000 μs) - limits downstream IC stress during worst-case surge events |
| Peak Pulse Power | 600 W (10/1000 μs waveform) - supports high-energy transients common in automotive load-dump or inductive switching |
| Junction Temperature Range | −55 to +175 °C - enables operation in engine control units and industrial motor drives with minimal derating |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded outline compatible with legacy through-hole assembly and automated taping |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy body, matte tin-plated leads compliant with J-STD-002 solderability. No polarity marking - bidirectional symmetry eliminates orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity - no fixed polarity assignment |
| Lead 1 | Current path input/output | Conducts surge current in either direction; requires ≥0.375″ (9.5 mm) lead length for rated power dissipation |
| Lead 2 | Current path input/output | Paired with Lead 1 to complete low-inductance surge path; thermal resistance RθJL = 20 °C/W referenced to lead |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables ±5 % VBR tolerance and stable leakage (<1 μA at VWM) over 1000-hour HTOL stress |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 5a (load dump) energy without degradation when mounted per JEDEC standards |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling (−40 to +125 °C, 1000 cycles) and unbiased HTRB at 175 °C |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes overvoltage exposure to protected ICs - e.g., clamps 56 V nominal line to ≤77 V during 7.8 A surge |
| UL 94 V-0 molding compound | Meets flammability requirements for enclosed industrial enclosures and automotive junction boxes |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | DO-214AA package, 58 V VBR, same 600 W rating but lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for surface-mount PCBs with limited board space; not axial-compatible | Select SMBJ58CA for SMT designs requiring higher thermal efficiency and smaller footprint. |
| 1.5KE56CA | Same DO-15 package, identical VBR range, but rated for 1500 W peak pulse power (10/1000 μs) | Used where higher single-event surge margin is needed (e.g., outdoor telecom cabinets) | Choose 1.5KE56CA when system-level testing reveals need for >600 W headroom without changing layout. |
Compared with SMBJ58CA and 1.5KE56CA, the P6KE56CAHE3/54 offers optimal balance of AEC-Q101 qualification, axial lead compatibility, and cost-effective 600 W surge handling - making it preferred for automotive and industrial through-hole production where qualification and legacy assembly are mandatory.

FAQ
What is the meaning of the 'CA' suffix in P6KE56CAHE3/54?
The 'CA' suffix in P6KE56CAHE3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, unlike unidirectional variants (e.g., P6KE56A) that require correct cathode orientation. This eliminates polarity-dependent placement errors in AC-coupled or differential signal paths.
Is P6KE56CAHE3/54 suitable for automotive applications?
Yes, P6KE56CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its −55 to +175 °C junction temperature range, validated thermal cycling performance, and compliance with load-dump surge profiles make it appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the clamping voltage of P6KE56CAHE3/54 compare to its breakdown voltage?
The P6KE56CAHE3/54 has a breakdown voltage (VBR) of 53.2–58.8 V at 1 mA and clamps to ≤77.0 V at 7.8 A (10/1000 μs). This clamping ratio of ~1.34 ensures protected circuits experience only moderate overvoltage during surge events - critical for safeguarding 3.3 V or 5 V logic interfaces downstream.
What is the significance of the 'HE3/54' suffix in P6KE56CAHE3/54?
The 'HE3' suffix indicates RoHS-compliant, AEC-Q101-qualified construction with JESD 201 Class 2 whisker resistance; '54' specifies the packaging format - 4000-piece 13-inch paper tape and reel. This ensures consistent assembly performance and regulatory compliance for high-reliability production runs.
Can P6KE56CAHE3/54 replace unidirectional TVS diodes like P6KE56A?
No - P6KE56CAHE3/54 is bidirectional and lacks polarity marking, while P6KE56A is unidirectional with a cathode band. Substituting them requires circuit review: P6KE56CAHE3/54 may be used in AC or floating applications, but will not provide correct forward conduction behavior in DC-biased unidirectional protection schemes.
