Product details
Overview
P6KE43CA-E3/54 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 43 V breakdown voltage (VBR min/max = 40.9–45.2 V at 1.0 mA), 36.8 V standoff voltage (VWM), 59.3 V maximum clamping voltage (VC) at 10.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE43CA-E3/54 datasheet, P6KE43CA-E3/54 pinout, P6KE43CA-E3/54 application, or P6KE43CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
Clamping performance is defined by VC = 59.3 V at IPPM = 10.1 A (10/1000 μs), with temperature coefficient of VBR = +0.101 %/°C. Junction-to-lead thermal resistance is 20 °C/W, supporting reliable operation up to TJ = 175 °C with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V / 45.2 V at 1.0 mA - defines precise voltage threshold where clamping initiates in both directions |
| VWM | 36.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 59.3 V at 10.1 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - surge energy handling capacity per single transient event, derated above 25 °C ambient |
| RθJL | 20 °C/W - enables thermal design with lead-mounted heatsinking; limits junction rise to ≤20 °C per watt dissipated |
| TJ max | +175 °C - supports operation in under-hood automotive environments and high-temperature industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads. Dimensions: 3.3–3.5 mm diameter × 25.4 mm minimum length; lead spacing ≥9.5 mm. RoHS-compliant (E3 suffix), UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; identical electrical behavior in either direction - connects across protected line and return |
| Lead 1 / Lead 2 | Current path terminals | Leads serve as both electrical interface and primary heat conduction path to PCB; RθJL = 20 °C/W assumes 0.375" (9.5 mm) lead length |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5 %) and long-term leakage stability under humidity and bias stress |
| 600 W peak pulse power (10/1000 μs) | Withstands common lightning-induced surges (IEC 61000-4-5 Level 3: 1 kV/2 Ω) without degradation |
| Fast response time <1 ns | Clamps transients before sensitive downstream components (e.g., MCU I/O pins) experience overvoltage damage |
| AEC-Q101 qualification | Validated for automotive powertrain, body electronics, and ADAS modules requiring zero-failure field reliability |
| UL 497B recognition (QVGQ2) | Meets safety standard for telecom/data line protectors - simplifies system-level certification for industrial gateways |
Applications
| Automotive Body Control Module | Industrial PLC Analog Input Protection |

IC Role / Device Role / Timing Role: Bidirectional clamp between signal and return lines, absorbing ±8 kV contact ESD per IEC 61000-4-2. Use Value: Maintains signal integrity below 36.8 V operating range while clamping fast transients to 59.3 V - no false triggering or offset drift. |
| Telecom Power Feeding Interface | Consumer Appliance Motor Drive Protection |
|
Use Scenario: Guarding PoE-powered Ethernet switch ports against induced surges from nearby AC mains cabling. IC Role / Device Role / Timing Role: Line-to-line TVS on data pairs, leveraging bidirectional symmetry to handle differential-mode transients.

Use Scenario: Shielding BLDC motor driver ICs from back-EMF spikes generated during commutation in HVAC blowers. IC Role / Device Role / Timing Role: Rail-to-rail suppressor across VDD and GND of gate drivers, activated only during >40 V flyback events. Use Value: Absorbs 600 W pulses without failure, enabling use of cost-optimized 60 V-rated MOSFETs instead of 100 V+ devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43CA | Same VBR range (40.9–45.2 V) and VC (59.3 V), but SMC (DO-214AB) package - 1.5× smaller footprint, higher IPPM (12.3 A) | Preferred for space-constrained PCBs; requires re-layout due to different pad geometry and thermal path | Select SMBJ43CA when board area is limited and thermal management uses copper pour rather than lead conduction |
| 1.5KE43CA | Same electrical specs but larger DO-201AD package - higher PPPM (1500 W), lower RθJA (30 °C/W vs. 75 °C/W), same DO-15 lead form factor | Used where higher surge margin is required (e.g., outdoor telecom cabinets), with identical mounting compatibility | Choose 1.5KE43CA if system-level surge testing exceeds IEC 61000-4-5 Level 4 and DO-15 mechanical fit is mandatory |
Compared with SMBJ43CA and 1.5KE43CA, P6KE43CA-E3/54 offers optimal balance of DO-15 legacy compatibility, AEC-Q101 qualification, and UL 497B recognition - making it preferred for automotive replacement modules and industrial retrofits where footprint and qualification alignment are critical.

FAQ
What is the breakdown voltage tolerance for P6KE43CA-E3/54?
The P6KE43CA-E3/54 has a specified breakdown voltage range of 40.9 V to 45.2 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 43 V rating. This tight tolerance ensures consistent clamping initiation across production lots and supports predictable system-level surge margin calculations in designs using P6KE43CA-E3/54.
Is P6KE43CA-E3/54 suitable for automotive applications?
Yes, P6KE43CA-E3/54 is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade product documentation. Its construction - glass-passivated junction, DO-15 leadframe, and UL 497B recognition - meets requirements for under-hood and cabin electronics. The P6KE43CA-E3/54 is deployed in body control modules, lighting drivers, and sensor interfaces where transient immunity and long-term reliability are mandatory.
How does the clamping voltage of P6KE43CA-E3/54 compare to its standoff voltage?
P6KE43CA-E3/54 has a standoff voltage (VWM) of 36.8 V and a maximum clamping voltage (VC) of 59.3 V at 10.1 A. This 22.5 V differential defines the protective window: the device remains non-conductive below 36.8 V, then limits transient excursions to no more than 59.3 V - ensuring downstream 40 V-rated components remain within safe operating area during surge events.
Can P6KE43CA-E3/54 be used in bidirectional AC signal lines?
Yes, P6KE43CA-E3/54 is specifically designed for bidirectional applications, as indicated by the "CA" suffix. Its symmetrical VBR and VC characteristics in both polarities allow direct placement across AC-coupled data lines (e.g., RS-485, CAN FD), audio paths, or transformer secondaries without polarity concerns - unlike unidirectional variants such as P6KE43A.
What is the thermal resistance profile of P6KE43CA-E3/54?
P6KE43CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. In practical layout, this means that with 0.375" (9.5 mm) lead length and minimal copper, 1 W of surge dissipation raises junction temperature by 20 °C above lead temperature - critical for ensuring TJ stays below 175 °C during repetitive surge testing.
