Product details
Overview
P6KE56CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 56 V breakdown voltage (VBR min = 53.2 V, max = 58.8 V), 47.8 V stand-off voltage (VWM), 77.0 V maximum clamping voltage at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE56CHE3/54 datasheet, P6KE56CHE3/54 pinout, P6KE56CHE3/54 application, or P6KE56CHE3/54 equivalent, key selection criteria include bi-directional clamping symmetry, AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, and verified 175 °C junction temperature operation under transient stress.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding VWM = 47.8 V, it avalanches symmetrically in both directions to clamp voltage at ≤77.0 V while diverting up to 7.8 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at VWM) across -55 °C to +175 °C.
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); power derating begins above 25 °C ambient, with full 5.0 W dissipation only at TL = 75 °C on infinite heatsink. No polarity marking is present - consistent with bi-directional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at 1.0 mA test current - defines reliable avalanche initiation threshold in both directions |
| VWM | 47.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 77.0 V at 7.8 A (10/1000 µs) - peak clamped voltage seen by protected circuit during surge |
| PPPM | 600 W - surge energy handling capacity per single transient, enabling robust ESD and load-dump immunity |
| TJ max | +175 °C - supports under-hood automotive placement and high-temperature industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with matte tin-plated leads, UL 94 V-0 molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with glass-passivated chip; no polarity marking (bi-directional); leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets JESD 201 class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction - either lead serves as input/output; clamps equally for positive or negative transients |
| Lead 1 / Lead 2 | Current path to PCB trace or heatsink | Leads conduct surge current to ground plane; thermal resistance RθJL = 20 °C/W enables direct lead-to-copper thermal coupling |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and low leakage (<1 µA) over lifetime and temperature |
| 600 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and IEC 61000-4-5 Level 3 surges without degradation |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics - includes HTGB, TC, and uHAST testing |
| Bi-directional clamping symmetry | Identical VBR, VC, and leakage in both polarities - eliminates need for orientation-aware layout |
| UL 94 V-0 molding compound | Self-extinguishing epoxy prevents flame propagation in enclosed enclosures and battery management systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | DO-214AA package; 58 V VBR; 600 W rating; lower RθJA (50 °C/W) but no AEC-Q101 qualification | Preferred for space-constrained SMT layouts; unsuitable for under-hood automotive use | Select when board area is limited and automotive qualification is not required |
| 1.5KE56CA | Same DO-204AC package; 56 V VBR; 1500 W rating; higher VC = 93.6 V; commercial grade only | Higher surge margin for infrequent, high-energy events; larger footprint and higher clamping voltage | Choose for non-automotive industrial systems needing >600 W headroom and accepting higher clamping |
Compared with SMBJ58CA and 1.5KE56CA, P6KE56CHE3/54 uniquely combines AEC-Q101 qualification, DO-204AC axial form factor, and precise 77.0 V clamping - making it optimal for cost-sensitive, thermally constrained automotive and industrial designs requiring certified reliability.

FAQ
What does the 'HE3/54' suffix mean in P6KE56CHE3/54?
The HE3 suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 class 2 whisker resistance; '/54' denotes packaging in 13-inch paper tape and reel with 4000 units per reel. This makes P6KE56CHE3/54 suitable for automated SMT assembly in automotive production lines where traceability and reliability are mandatory. The full designation P6KE56CHE3/54 reflects both performance grade and logistics format.
Is P6KE56CHE3/54 unidirectional or bidirectional?
P6KE56CHE3/54 is a bi-directional TVS diode - confirmed by the 'C' in its part number (P6KE56C) and absence of cathode band marking. Electrical characteristics apply identically in both polarities: VBR = 53.2–58.8 V, VC = 77.0 V, and leakage <1.0 µA at VWM = 47.8 V regardless of voltage polarity. This symmetry simplifies layout in AC-coupled or floating signal paths where polarity reversal may occur.
What is the maximum clamping voltage of P6KE56CHE3/54 under surge conditions?
The maximum clamping voltage of P6KE56CHE3/54 is 77.0 V, measured at IPPM = 7.8 A using the standard 10/1000 µs double-exponential surge waveform. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events and is guaranteed across the full operating temperature range (-55 °C to +175 °C). Designers must ensure downstream components tolerate ≤77.0 V peak.
Can P6KE56CHE3/54 replace P6KE56A in an existing design?
No - P6KE56CHE3/54 is bi-directional (P6KE56C), while P6KE56A is unidirectional. Their VBR and VC values differ: P6KE56A has VC = 77.0 V but requires correct cathode orientation and exhibits forward conduction below 3.5 V. Substituting P6KE56CHE3/54 would eliminate polarity sensitivity but introduce unintended conduction during normal forward bias. Always verify circuit topology before interchanging uni- and bi-directional variants of P6KE56CHE3/54.
What is the thermal resistance specification for P6KE56CHE3/54?
P6KE56CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W, measured under standard conditions (TA = 25 °C, infinite heatsink). These values govern power derating: at TL = 75 °C, the device sustains 5.0 W continuous dissipation; above that, linear derating applies per Figure 5 in the datasheet. Proper PCB copper land area directly contacting the leads is essential to achieve rated thermal performance for P6KE56CHE3/54.
