Product details
Overview
P6KE24C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 22.8 V to 25.2 V breakdown voltage at 1 mA, 20.5 V stand-off voltage, 33.2 V maximum clamping voltage at 18.1 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE24C-E3/73 datasheet, P6KE24C-E3/73 pinout, P6KE24C-E3/73 application, or P6KE24C-E3/73 equivalent, this device serves as a robust, low-leakage (≤1.0 μA at 20.5 V), fast-response (<1 ns) protection solution for sensitive analog inputs, sensor interfaces, and 24 V industrial control bus lines where bidirectional surge immunity is required.
Technical Context
The P6KE24C-E3/73 implements a glass-passivated silicon junction optimized for bi-directional transient suppression without polarity dependence. Its clamping behavior is defined by a 33.2 V maximum VC at 18.1 A IPPM under 10/1000 μs waveform, with thermal resistance RθJL of 20 °C/W enabling reliable operation up to 175 °C junction temperature.
It operates across -55 °C to +175 °C, supports 100 A non-repetitive forward surge (IFSM), and maintains ≤1.0 μA reverse leakage at its 20.5 V stand-off voltage - critical for low-power sensor nodes and battery-backed systems where standby current must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 22.8 V min / 25.2 V max at 1 mA - defines precise voltage threshold where clamping initiates in both directions |
| Stand-off Voltage (VWM) | 20.5 V - maximum continuous working voltage before leakage exceeds 1.0 μA; sets safe operating margin below VBR |
| Clamping Voltage (VC) | 33.2 V at 18.1 A IPPM - limits transient-induced overvoltage seen by protected ICs during 10/1000 μs surges |
| Peak Pulse Power (PPPM) | 600 W (10/1000 μs) - sustains high-energy transients common in automotive load-dump or inductive switching events |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy, compatible with through-hole assembly |
| Qualification | AEC-Q101 qualified - validated for automotive applications including engine control units and body electronics |
| Leakage Current (ID) | ≤1.0 μA at 20.5 V - ensures minimal impact on high-impedance sensor bias networks and precision reference circuits |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy-molded case with matte tin-plated leads solderable per J-STD-002. Bi-directional construction means no cathode marking; terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | Both leads function identically - conducts surge current in either direction when voltage exceeds ±22.8 V |
| Lead 1 / Lead 2 | Connection to protected line and ground/reference | Placed across circuit node and return path; no polarity orientation required during placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable breakdown characteristics and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients from inductive load switching in 24 V industrial PLCs and automotive ECUs |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD >15 kV), improving protection margin for downstream ICs |
| UL 94 V-0 flammability rating | Ensures flame-retardant encapsulation for safety-critical applications in consumer and industrial equipment |
Applications
| Automotive Sensor Protection | Industrial 24 V I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA (SMB) package; same 24 V bi-directional rating but lower 600 W PPPM limited to 10/1000 μs; RθJA = 40 °C/W vs. 75 °C/W for P6KE24C-E3/73 | Better suited for surface-mount PCBs with space constraints; less effective in high-ambient-temperature through-hole designs | Select SMBJ24CA when board real estate is limited and thermal management via PCB copper is feasible. |
| 1.5KE24CA | Higher 1500 W PPPM rating; larger DO-201AD (DO-27) package; 33.2 V VC at 45.5 A IPPM; same VBR/VWM specs | Used where higher surge energy (e.g., IEC 61000-4-5 Level 4) must be absorbed without derating | Choose 1.5KE24CA when system-level surge testing requires >600 W headroom and board layout accommodates larger axial package. |
Compared with SMBJ24CA and 1.5KE24CA, the P6KE24C-E3/73 offers optimal balance of proven AEC-Q101 reliability, DO-15 through-hole compatibility, and sufficient 600 W surge handling for cost-sensitive automotive and industrial control applications - without requiring PCB redesign or thermal derating penalties.

FAQ
What does the "C" suffix in P6KE24C-E3/73 indicate?
The "C" in P6KE24C-E3/73 denotes bi-directional configuration - meaning the device clamps voltage transients equally in both polarities, with no cathode marking required. This distinguishes it from uni-directional variants like P6KE24A-E3/73, which have a cathode band and conduct only in reverse bias. The P6KE24C-E3/73 is specified for symmetric breakdown (22.8–25.2 V) and clamping in either direction.
Is P6KE24C-E3/73 RoHS compliant and halogen-free?
Yes, P6KE24C-E3/73 carries the "E3" suffix, confirming RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. Its matte tin-plated leads meet J-STD-002 solderability standards, and the UL 94 V-0 epoxy molding compound ensures flame-retardant operation without brominated or chlorinated additives.
How does P6KE24C-E3/73 perform under elevated ambient temperatures?
P6KE24C-E3/73 derates linearly above 25 °C ambient: its 600 W peak pulse power drops to ~400 W at 75 °C and ~200 W at 125 °C, per Figure 2 in the datasheet. Junction temperature must remain ≤175 °C; thermal resistance RθJL = 20 °C/W allows direct lead-to-heatsink conduction, making it suitable for thermally constrained through-hole layouts.
Can P6KE24C-E3/73 replace P6KE24A-E3/73 in a circuit?
No - P6KE24C-E3/73 is bi-directional while P6KE24A-E3/73 is uni-directional with a defined cathode. Substituting them requires verifying circuit polarity: P6KE24C-E3/73 may be used in place of P6KE24A-E3/73 only if the protected node has no DC bias or if symmetrical clamping is acceptable. Reverse-bias-only applications (e.g., DC power rail protection) require the uni-directional version.
What is the maximum clamping voltage of P6KE24C-E3/73 under standard test conditions?
The maximum clamping voltage (VC) of P6KE24C-E3/73 is 33.2 V, measured at 18.1 A peak pulse current (IPPM) using a 10/1000 μs waveform per Figure 1. This value represents the upper limit of voltage imposed on the protected circuit during worst-case surge events and is guaranteed across the full operating temperature range (-55 °C to +175 °C).
