Product details
Overview
P6KE47CAHE3/54 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 47 V breakdown voltage (VBR min/max = 44.7–49.4 V), 40.2 V standoff voltage (VWM), 64.8 V maximum clamping voltage at 9.3 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 P6KE47CAHE3/54 datasheet, P6KE47CAHE3/54 pinout, P6KE47CAHE3/54 application, or P6KE47CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and low leakage (<1 μA at VWM) under standby conditions.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche breakdown in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response time (<1 ns), while the DO-15 package supports manual or automated through-hole assembly with matte tin-plated leads compliant to J-STD-002.
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), allowing reliable operation up to TJ = 175 °C. The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V - defines guaranteed avalanche conduction onset range under 1 mA test current; critical for margin-based transient threshold setting |
| VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for normal-mode circuit bias |
| VC @ IPPM | 64.8 V at 9.3 A - clamped voltage during 10/1000 μs surge; determines worst-case stress on downstream components |
| PPPM | 600 W - peak pulse power handling with 0.01 % duty cycle; enables robust protection against lightning-induced surges |
| IPPM | 9.3 A - maximum non-repetitive surge current for 10/1000 μs waveform; used to size series impedance and fuse coordination |
| TJ max. | 175 °C - maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for engine control and ADAS subsystems |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with axial leads; no polarity marking for bidirectional configuration; matte tin-plated terminals solderable per J-STD-002; flammability rating UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between leads; either terminal serves as cathode or anode depending on transient polarity - eliminates orientation errors during placement |
| Lead 1 / Lead 2 | Current path to PCB trace or heatsink | Leads conduct surge current to external copper; thermal resistance RθJL = 20 °C/W assumes 9.5 mm lead length - impacts layout-dependent power derating |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables ±5 % VBR tolerance and stable leakage (<1 μA at VWM) across -55 °C to +175 °C operating range |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when paired with appropriate series impedance |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including powertrain and body electronics - includes HTGB, TC, and H3TRB testing |
| UL 497B recognized (QVGQ2) | Meets safety requirements for telecom line interface protection; eliminates need for separate certification in end equipment |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), reducing risk of latch-up in protected ICs |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |

IC Role / Device Role / Timing Role: UL 497B recognition (QVGQ2) permits direct use in telecom safety isolation barriers without additional certification overhead. Use Value: Symmetrical bidirectional behavior eliminates need for polarity-aware routing - simplifies PCB layout for differential pairs like RS-485 or USB D+/D−. |
Use Scenario: Clamping back-EMF spikes generated by brushed DC motors in washing machine control boards during commutation. IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge outputs to absorb inductive kickback energy before MOSFET drain-source breakdown. Use Value: 100 A IFSM rating handles repetitive motor stall currents; DO-15 package fits standard through-hole footprints used in cost-sensitive white goods designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ45CA | DO-214AA package, 45 V VBR, 600 W rating, lower RθJA (50 °C/W) but no AEC-Q101 qualification | Suitable for space-constrained consumer electronics; lacks automotive reliability validation | Select SMBJ45CA only when board space is limited and AEC-Q101 is not required |
| 1.5KE47CA | Same DO-15 package, identical VBR/VWM/VC, but commercial-grade (E3 suffix), not AEC-Q101 qualified | Acceptable for industrial/commercial systems where automotive qualification is unnecessary | Choose 1.5KE47CA for cost-sensitive non-automotive applications requiring identical electrical specs |
Compared with SMBJ45CA and 1.5KE47CA, P6KE47CAHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and UL 497B recognition - making it the only option among the three qualified for automotive powertrain and body control modules requiring full safety certification.

FAQ
What is the breakdown voltage tolerance for P6KE47CAHE3/54?
The P6KE47CAHE3/54 has a specified breakdown voltage range of 44.7 V to 49.4 V at 1 mA test current, corresponding to a ±5 % tolerance around the nominal 47 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature extremes from -55 °C to +175 °C, which is essential for consistent protection in automotive and industrial applications where margin analysis is critical.
Is P6KE47CAHE3/54 suitable for automotive applications?
Yes, P6KE47CAHE3/54 is AEC-Q101 qualified (indicated by the HE3 suffix) and tested for temperature cycling, high-temperature reverse bias, and humidity robustness. It is explicitly intended for automotive use cases such as LIN bus protection, body control modules, and sensor interfaces where reliability under harsh thermal and electrical stress is mandatory - unlike commercial-grade variants like P6KE47CAE3/54.
How does the bidirectional nature of P6KE47CAHE3/54 affect its PCB layout?
The bidirectional design of P6KE47CAHE3/54 means both leads are functionally identical - there is no anode or cathode marking, and orientation during placement has no electrical impact. This eliminates polarity-check steps in assembly and simplifies routing for AC-coupled or floating signal lines, such as RS-485 buses or transformer-isolated power supplies, where traditional unidirectional TVS diodes would require careful orientation verification.
What is the maximum clamping voltage of P6KE47CAHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE47CAHE3/54 is 64.8 V at 9.3 A peak pulse current with a 10/1000 μs waveform. This value represents the worst-case voltage seen by downstream components during a standardized surge event and is used to verify that protected ICs remain within their absolute maximum ratings - for example, ensuring 5 V logic interfaces do not experience more than ~13 V overvoltage margin.
Does P6KE47CAHE3/54 meet any safety certifications?
Yes, P6KE47CAHE3/54 carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional devices, complying with UL 497B for telecommunications protectors. This certification validates its suitability in safety-critical telecom line interfaces and reduces end-equipment certification burden - a key differentiator versus non-recognized alternatives.
