Product details
Overview
P6KE11C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 11 V breakdown voltage (VBR min = 10.5 V, max = 11.6 V), 9.4 V stand-off voltage (VWM), 15.6 V maximum clamping voltage at 38.5 A peak pulse current (IPPM), 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 P6KE11C-E3/73 datasheet, P6KE11C-E3/73 pinout, P6KE11C-E3/73 application, or P6KE11C-E3/73 equivalent, key selection criteria include its bi-directional polarity, DO-204AC (DO-15) package, low clamping ratio (VC/VWM ≈ 1.66), AEC-Q101 qualification (via HE3 variant), and compatibility with 8.3 ms surge waveforms per JESD22-A112.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 9.4 V), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5 μA at VWM).
The P6KE11C-E3/73 is rated for -55 °C to +175 °C operating junction temperature, with thermal resistance RθJL = 20 °C/W and RθJA = 75 °C/W. It supports repetitive 0.01% duty cycle pulses and complies with UL 497B recognition (QVGQ2) for telecom and industrial surge protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1.0 mA test current - defines precise clamping onset threshold for bi-directional overvoltage events |
| VWM | 9.4 V - maximum continuous working voltage before leakage exceeds 5 μA; sets safe operating margin below breakdown |
| VC @ IPPM | 15.6 V at 38.5 A (10/1000 μs) - actual worst-case clamped voltage seen by protected circuit during surge |
| PPPM | 600 W - peak transient energy absorption capability without failure; enables robust protection against lightning-induced surges |
| IPPM | 38.5 A - maximum non-repetitive surge current the device safely clamps; determines minimum series impedance required |
| TJ max | +175 °C - high-temperature operation support for under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.300" lead length, UL 94 V-0 molded epoxy body |
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 polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional clamping node | Either terminal serves as transient sink; no cathode band marking - enables flexible PCB layout without orientation constraints |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads provide mechanical mounting and thermal conduction path; RθJL = 20 °C/W enables effective heat dissipation into PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity stress |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) when paired with appropriate series impedance |
| AEC-Q101 qualified variant available (P6KE11CHE3) | Validated for automotive powertrain and body electronics where qualification to stress-test standards is mandatory |
| Low clamping ratio (VC/VWM = 1.66) | Minimizes voltage overshoot during clamping - critical for protecting 12 V logic interfaces and analog sensor inputs |
| UL 497B recognized (QVGQ2) | Meets safety requirements for telecom and industrial signal-line protectors without additional certification effort |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same VWM (9.4 V) and VC (19.9 V), but SMC package (higher IPPM = 43.2 A); lower RθJA (50 °C/W) | Better thermal performance in high-density layouts; requires rework of footprint and stencil | Select when higher surge margin or improved thermal management is needed; not drop-in compatible |
| 1.5KE11CA | Same electrical specs but higher PPPM = 1500 W; larger DO-201AD package; VF = 3.5 V | Used where legacy 1.5 kW surge standards apply (e.g., older telecom specs); less space-constrained designs | Choose for applications requiring higher single-pulse energy handling; board area and cost penalty applies |
Compared with SMBJ11CA and 1.5KE11CA, the P6KE11C-E3/73 offers optimal balance of compact DO-15 footprint, AEC-Q101-ready variants, and proven field reliability in cost-sensitive automotive and industrial modules - making it preferred where board space and qualification alignment outweigh raw power rating.

FAQ
What is the polarity configuration of the P6KE11C-E3/73?
The P6KE11C-E3/73 is a bi-directional TVS diode, meaning it provides symmetrical clamping for positive and negative transients without polarity marking on the DO-204AC package. This allows flexible placement across AC-coupled lines or differential pairs, and eliminates orientation errors during assembly. Its VBR and VC values apply identically in both directions, as confirmed in Vishay's 88369 datasheet.
Does the P6KE11C-E3/73 meet AEC-Q101 requirements?
The P6KE11C-E3/73 itself is the commercial-grade variant (E3 suffix); however, the functionally identical P6KE11CHE3 is AEC-Q101 qualified. Both share identical electrical specs and DO-204AC packaging, differing only in test documentation and traceability. For automotive applications requiring formal qualification, P6KE11CHE3 must be specified - the P6KE11C-E3/73 remains suitable for industrial and consumer use where AEC-Q101 is not mandated.
What is the maximum clamping voltage of the P6KE11C-E3/73 under surge conditions?
The P6KE11C-E3/73 has a maximum clamping voltage (VC) of 15.6 V at 38.5 A peak pulse current with a 10/1000 μs waveform, as specified in the Vishay 88369 datasheet. This value represents the worst-case voltage imposed on the protected circuit during standardized surge testing and is critical for ensuring downstream components (e.g., 12 V logic ICs) remain within absolute maximum ratings.
How does the P6KE11C-E3/73 compare to the P6KE11A variant?
The P6KE11C-E3/73 is bi-directional, whereas the P6KE11A is uni-directional with a cathode band marking. Their VBR, VWM, and VC values are identical, but the P6KE11A conducts forward current up to 100 A (IFSM), while the P6KE11C-E3/73 does not specify IFSM due to symmetrical structure. Use P6KE11C-E3/73 for AC or bidirectional signal lines; choose P6KE11A only when unidirectional clamping with high forward surge capability is required.
What package type and lead finish does the P6KE11C-E3/73 use?
The P6KE11C-E3/73 uses the DO-204AC (DO-15) package: axial-leaded, 0.300" minimum lead length, with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The epoxy body meets UL 94 V-0 flammability rating, and the E3 suffix confirms RoHS compliance per Directive 2011/65/EU.
