Product details
Overview
P6KE56A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary-level overvoltage protection of sensitive electronics. It features a 56 V breakdown voltage (VBR min/max = 53.2–58.8 V), 47.8 V stand-off voltage (VWM), 77.0 V maximum clamping voltage (VC) at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and DC power rail protection.
For engineers reviewing the P6KE56A-E3/54 datasheet, P6KE56A-E3/54 pinout, P6KE56A-E3/54 application, or P6KE56A-E3/54 equivalent, key selection criteria include clamping performance under 7.8 A surge, unidirectional polarity with cathode band marking, DO-15 mechanical compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE56A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) to transient events and low incremental surge resistance for effective voltage clamping. Its unidirectional configuration enables asymmetric protection on DC-biased lines, where reverse conduction is blocked until breakdown threshold is exceeded.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting continuous power dissipation of 5.0 W at TL = 75 °C. It sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits +0.103 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across -55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at IT = 1.0 mA - defines precise avalanche onset window for reliable triggering without premature conduction |
| VWM | 47.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA, sets safe DC bias margin |
| VC @ IPPM | 77.0 V at 7.8 A (10/1000 μs) - clamping voltage limiting downstream component stress during surge events |
| PPPM | 600 W - peak transient energy absorption capacity, enabling protection against IEC 61000-4-5 Level 4 surges |
| IFSM | 100 A (8.3 ms half-sine) - surge current handling for inductive switch-off transients in motor control or relay circuits |
| TJ max. | +175 °C - high-temperature junction rating supports under-hood automotive and industrial ambient conditions |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.242–0.258 inch body length, UL 94 V-0 compliant molding |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; no polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional protection configurations |
| Cathode | Avalanche conduction terminal | Marked with color band; connected to protected line (e.g., 48 V rail or sensor output) to clamp positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable avalanche characteristics and long-term reliability under repeated surge stress without degradation |
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and inductive switching spikes in industrial power systems |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control modules and body electronics requiring extended temperature cycling |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage exposure to downstream ICs such as CAN transceivers or microcontrollers during transient events |
| Solderable per J-STD-002/JESD 22-B102 | Ensures consistent lead wetting and joint integrity during wave or reflow soldering processes in high-volume manufacturing |
Applications
| Automotive Sensor Protection | Industrial DC Power Rail |
|---|---|
|
Use Scenario: Protecting analog outputs of pressure/temperature sensors in engine bay environments exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and ground to clamp positive transients while blocking reverse leakage. Use Value: Limits voltage seen by downstream op-amp or ADC input to ≤77.0 V during 7.8 A surge, preventing latch-up or oxide damage. |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on main rail, coordinated with upstream fuse for fail-safe short-circuit behavior. Use Value: Absorbs 600 W transient energy without degradation, maintaining system uptime during frequent relay switching cycles. |
| Telecom Line Interface | Consumer Power Adapter Output |
|
Use Scenario: Secondary-side surge suppression on Ethernet PHY power pins or RS-485 VCC rails subjected to ESD and fast transients. IC Role / Device Role / Timing Role: Standoff-rated protector (VWM = 47.8 V) placed directly at IC supply pin to minimize trace inductance impact. Use Value: Clamps 10/1000 μs surges to 77.0 V within <1 ns, preserving signal integrity and preventing reset corruption in communication ICs. |
Use Scenario: Output overvoltage protection in USB-C PD adapters where secondary-side regulation failure could expose connected devices. IC Role / Device Role / Timing Role: Last-line defense TVS between transformer secondary and synchronous rectifier MOSFET drain. Use Value: Triggers at 53.2 V and clamps to 77.0 V before downstream capacitors exceed rated voltage, avoiding catastrophic rupture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | DO-214AA package, 58 V VBR, 600 W rating, but lower IPPM (6.8 A) and higher VC (93.6 V) | Suitable for PCB space-constrained designs; less effective clamping on high-current surges | Select when board real estate is limited and surge currents remain below 6.8 A |
| 1.5KE56A | Same DO-15 package, identical VBR/VWM/VC, but 1.5 kW rating (10/1000 μs) and higher IFSM (200 A) | Better suited for high-energy industrial transients where 600 W is marginal | Choose when legacy DO-15 footprint must be retained but higher surge margin is required |
Compared with SMBJ58A and 1.5KE56A, the P6KE56A-E3/54 offers optimal balance of clamping performance (77.0 V), compact DO-15 fit, and AEC-Q101 qualification - making it preferred for cost-sensitive automotive and industrial applications where 600 W surge capacity suffices.

FAQ
What is the polarity configuration of the P6KE56A-E3/54?
The P6KE56A-E3/54 is a unidirectional TVS diode, with cathode identified by a color band on the package body. It conducts only in reverse bias above its breakdown voltage, blocking forward current up to 3.5 V at 50 A. This configuration makes the P6KE56A-E3/54 ideal for DC-biased signal or power lines where negative transients are not expected.
Does the P6KE56A-E3/54 meet automotive qualification standards?
Yes, the P6KE56A-E3/54 carries the E3 suffix, indicating RoHS compliance and AEC-Q101 qualification per Vishay documentation. This certification validates its suitability for automotive applications including engine control units, body electronics, and ADAS sensor modules operating across -55 °C to +175 °C junction temperatures.
What is the maximum clamping voltage of the P6KE56A-E3/54 under surge conditions?
The P6KE56A-E3/54 has a maximum clamping voltage (VC) of 77.0 V at 7.8 A peak pulse current with a 10/1000 μs waveform. This value represents the upper voltage limit imposed on protected circuitry during standardized surge events, ensuring downstream components like microcontrollers or transceivers remain within safe operating limits.
How does the P6KE56A-E3/54 compare to the 1.5KE56A in terms of surge capability?
The P6KE56A-E3/54 delivers 600 W peak pulse power, whereas the 1.5KE56A provides 1500 W - a 2.5× higher surge rating. Both share identical VBR (53.2–58.8 V), VWM (47.8 V), and DO-15 packaging, but the 1.5KE56A supports 200 A IFSM versus 100 A for the P6KE56A-E3/54, making it better suited for high-energy industrial transients.
What is the thermal resistance specification for the P6KE56A-E3/54?
The P6KE56A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W. These values enable 5.0 W continuous power dissipation at lead temperature (TL) of 75 °C, guiding heatsinking decisions and layout for sustained operation in enclosed industrial enclosures.
