Product details
Overview
P6KE30CA-E3/73 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 30 V breakdown voltage (VBR min/max = 28.5–31.5 V at 1.0 mA), 41.4 V maximum clamping voltage (VC) at 14.5 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 P6KE30CA-E3/73 datasheet, P6KE30CA-E3/73 pinout, P6KE30CA-E3/73 application, or P6KE30CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at 25.6 V), and AEC-Q101 qualification status for automotive-grade reliability.
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 constraints. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping under repetitive transients.
The P6KE30CA-E3/73 delivers fast response time (<1.0 ns), low thermal resistance (RθJL = 20 °C/W), and operates across –55 °C to +175 °C junction range. It is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 0.097 %/°C temperature coefficient of VBR, supporting stable performance in thermally varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at IT = 1.0 mA - defines reliable conduction onset threshold for transient suppression |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 41.4 V at 14.5 A (10/1000 μs) - clamping voltage limiting downstream component stress during surge |
| PPPM | 600 W - peak transient energy handling capacity without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current robustness for inductive load switching events |
| TJ max | +175 °C - enables operation in high-temperature engine bay or industrial power supply environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports efficient heat dissipation through PCB traces |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Bidirectional construction means no polarity marking; terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetric) | Bidirectional avalanche junction terminal | Either lead serves as input/output path; identical clamping behavior in both directions |
| Lead 1 / Lead 2 | Current conduction path | Leads conduct surge current to ground or rail; require ≥0.375″ (9.5 mm) lead length for rated power derating |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) in industrial interfaces |
| AEC-Q101 qualified (HE3 suffix variant) | P6KE30CA-E3/73 is commercial grade; HE3 variant meets automotive stress test requirements |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio TVS devices |
| UL 94 V-0 molded compound | Flame-retardant encapsulation meets safety standards for enclosed power electronics |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Use Value: Supports IEEE 802.3 compliance with <1.0 μA leakage at 25.6 V, minimizing impact on signal integrity and bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA package, 33 V VBR, 600 W rating, lower RθJA (50 °C/W vs. 75 °C/W), surface-mount only | Requires PCB re-layout; better suited for high-density SMT designs with limited board space | Select SMBJ33CA when automated assembly and thermal performance on copper pour are prioritized over through-hole serviceability. |
| 1.5KE33CA | DO-201AD package, same VBR range, 1500 W PPPM, larger footprint, higher IPPM (38.2 A) | Over-spec'd for 600 W use cases; preferred where legacy through-hole designs demand higher surge margin | Choose 1.5KE33CA only if system-level testing confirms need for >600 W surge headroom or existing DO-201AD footprint reuse. |
Compared with SMBJ33CA and 1.5KE33CA, P6KE30CA-E3/73 offers optimal balance of cost, DO-15 through-hole compatibility, and verified 600 W surge handling - making it ideal for mid-volume industrial controls and automotive sub-systems where manual repairability and thermal derating predictability matter.

FAQ
What is the breakdown voltage tolerance for P6KE30CA-E3/73?
The P6KE30CA-E3/73 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current, representing ±5 % tolerance around the nominal 30 V rating. This tight VBR window ensures predictable clamping onset and consistent protection behavior across production lots. The value is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's 88369 datasheet revision 27-Sep-2021.
Is P6KE30CA-E3/73 RoHS compliant and halogen-free?
Yes, P6KE30CA-E3/73 carries the E3 suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and halogen-free status per IEC 61249-2-21. The molding compound meets UL 94 V-0 flammability rating, and matte tin plating satisfies J-STD-002 solderability requirements. These attributes are documented in Vishay's ordering information table and material categorization notice (doc?99912).
How does P6KE30CA-E3/73 differ from unidirectional P6KE30A?
P6KE30CA-E3/73 is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas P6KE30A is unidirectional with a band-marked cathode and forward voltage drop (VF = 3.5 V at 50 A). The CA version supports AC signal line protection and floating bus architectures, while the A version suits DC rail-to-ground clamping. Both share identical VBR, VC, and PPPM ratings.
What is the maximum allowable lead temperature during soldering for P6KE30CA-E3/73?
The maximum solder dip temperature for P6KE30CA-E3/73 is 275 °C for up to 10 seconds, per JESD 22-B106. This limit applies to wave soldering or hand-soldering processes. Exceeding this condition risks internal bond wire damage or delamination. The device's DO-15 package uses matte tin-plated leads qualified to J-STD-002, ensuring wetting integrity within this thermal envelope.
Can P6KE30CA-E3/73 be used in AEC-Q101 qualified designs?
P6KE30CA-E3/73 itself is commercial-grade (E3 suffix); however, the functionally identical P6KE30CAHE3/73 variant is AEC-Q101 qualified. For automotive applications requiring formal qualification, the HE3 version must be selected. Both share identical electrical specs and DO-15 packaging, differing only in test documentation and whisker resistance class (E3 = JESD 201 Class 1A, HE3 = Class 2).
