Product details
Overview
1.5KE130CA/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 130 V breakdown voltage (VBR = 124–137 V), 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤179 V at 8.4 A, making it suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial and automotive systems.
For engineers reviewing the 1.5KE130CA/54 datasheet, 1.5KE130CA/54 pinout, 1.5KE130CA/54 application, or 1.5KE130CA/54 equivalent, this device delivers verified bidirectional clamping performance with glass-passivated junction reliability, AEC-Q101 qualification availability, and UL 94 V-0 molded epoxy packaging - critical for robust overvoltage protection design.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its silicon avalanche junction provides sub-nanosecond response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation up to TJ = 175 °C. Standoff voltage is 111 V (VWM), with <1 µA reverse leakage at that level - ensuring minimal system loading during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - ensures reliable avalanche conduction onset across manufacturing tolerance and temperature |
| VWM | 111 V - maximum continuous working voltage before significant leakage begins |
| VC @ IPPM | ≤179 V at 8.4 A - defines worst-case clamped voltage during 1500 W transient event |
| PPPM | 1500 W - peak surge power handling capability per 10/1000 µs waveform |
| IPPM | 8.4 A - maximum non-repetitive peak current the device safely clamps |
| TJ max. | +175 °C - enables use in under-hood automotive and high-ambient industrial environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 compliant |
Pinout & Package
1.5KE130CA/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package. No polarity marking is present on bidirectional variants; terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead may connect to line or return; no cathode band - enables AC or floating protection without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|

| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-earth) when properly implemented |
| Sub-nanosecond response time | Clamps transients before sensitive downstream components experience damaging overvoltage |
| UL 94 V-0 epoxy molding | Meets flammability safety requirements for end equipment certification in consumer, industrial, and telecom applications |
| AEC-Q101 qualified versions available | Enables direct use in automotive electronics where qualification to stress-test standards is mandatory |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPPM (600 W), smaller SMB package (surface-mount), higher VC (219 V @ 2.7 A) | Best for space-constrained PCBs with lower surge exposure (e.g., USB ports, low-power sensors) | Select when board real estate is limited and full 1500 W rating is not required |
| 1.5KE130A | Unidirectional version; same VBR, VC, and PPPM; includes cathode band marking | Required only for DC-biased lines where polarity is fixed and reverse conduction must be blocked | Choose only if circuit topology mandates unidirectional clamping (e.g., +12 V supply rail with ground reference) |
Compared with SMBJ130CA and 1.5KE130A, the 1.5KE130CA/54 uniquely combines high-power bidirectional clamping in an axial-leaded through-hole package - ideal for legacy industrial designs, high-surge test fixtures, and applications requiring mechanical robustness and field-replaceability.

FAQ
What is the breakdown voltage range for the 1.5KE130CA/54?
The 1.5KE130CA/54 has a guaranteed breakdown voltage range of 124 V to 137 V at 1.0 mA test current (IT). This specification ensures predictable avalanche initiation across temperature and unit-to-unit variation, directly supporting design margin calculations for protected circuits. The 1.5KE130CA/54 maintains this VBR tolerance under JEDEC-standard test conditions and is validated per Vishay Document Number 88301.
Is the 1.5KE130CA/54 suitable for automotive applications?
Yes - while the base 1.5KE130CA/54 is commercial-grade, AEC-Q101 qualified versions (e.g., 1.5KE130CAHE3_B) are available and explicitly listed in the Vishay datasheet for automotive use. These variants undergo stress testing per AEC-Q101 including HTGB, HTRB, and temperature cycling, making them appropriate for body electronics, infotainment, and ADAS subsystems where qualification is mandatory. The 1.5KE130CA/54 itself shares identical electrical specs and package construction.
What is the clamping voltage of the 1.5KE130CA/54 at its rated peak pulse current?
The 1.5KE130CA/54 clamps to a maximum of 179 V at its rated peak pulse current of 8.4 A (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C) and represents the worst-case voltage seen by downstream components during a full 1500 W surge event. Designers use this VC to verify that protected ICs remain within their absolute maximum ratings.
Does the 1.5KE130CA/54 have polarity markings?
No - the 1.5KE130CA/54 is a bidirectional TVS diode and carries no polarity marking (e.g., cathode band) on its molded epoxy body. Its symmetrical construction allows either lead to be connected to line or return, simplifying layout for AC-coupled, differential, or floating signal paths. This distinguishes it from unidirectional variants like 1.5KE130A, which feature a visible cathode band.
What package type does the 1.5KE130CA/54 use, and what are its key mechanical properties?
The 1.5KE130CA/54 uses the DO-201AD (Case Style 1.5KE) axial-leaded package with 0.375" (9.5 mm) lead length. Its molded epoxy body meets UL 94 V-0 flammability rating, and matte tin-plated leads comply with J-STD-002 solderability and JESD 22-B102 whisker resistance standards. The 1.5KE130CA/54 weighs 0.968 g and is supplied in 13" paper tape and reel (54 per reel).
