Product details
Overview
1.5KE130CAHE3_B/C 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), clamping voltage of 179 V at 8.4 A, 1.0 µA max reverse leakage at 111 V, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges in industrial and automotive systems.
For engineers reviewing the 1.5KE130CAHE3_B/C datasheet, 1.5KE130CAHE3_B/C pinout, 1.5KE130CAHE3_B/C application, or 1.5KE130CAHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant HE3 packaging, and real-world clamping behavior under standardized 10/1000 µs surge conditions.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its symmetrical clamping behavior applies equally in both directions, with no polarity marking on the case - distinguishing it from unidirectional variants like 1.5KE130A.
The device is rated for 1500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and supports repetitive surge duty cycles up to 0.01 %. It meets UL 497B recognition (QVGQ2) and JESD 201 Class 2 whisker resistance due to its matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V at IT = 1.0 mA - defines precise voltage threshold where clamping initiates |

Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of IGBT gate driver inputs against inductive kickback from relay coils and solenoid switching. IC Role / Device Role: Bidirectional clamping element placed across gate-to-source terminals. Use Value: Limits transient voltage to ≤179 V, preventing gate oxide rupture in 600 V-class IGBTs while surviving repeated 1500 W pulses. |
Use Scenario: Surge suppression on LIN bus lines exposed to load dump and jump-start events in vehicle cabin networks. IC Role / Device Role: Standoff protector between LIN transceiver and wiring harness. Use Value: Maintains 111 V working voltage margin above 12 V nominal, clamps 10/1000 µs surges to 179 V without latch-up or parametric shift. |
| Telecom Power Feeds | Industrial Sensor Signal Conditioning |
Use Scenario: Primary protection on -48 V DC telecom power input against lightning-induced common-mode surges. IC Role / Device Role: Bidirectional shunt clamp on input rail referenced to chassis ground. Use Value: Absorbs 1500 W surges while holding rail voltage below 179 V - preserving upstream DC/DC converter integrity. |
Use Scenario: Protection of 4–20 mA current loop analog inputs in PLC analog input modules subjected to field wiring ESD and cable coupling. IC Role / Device Role: Differential-mode suppressor across loop terminals. Use Value: Clamps fast transients to <180 V with <1 µA leakage at 111 V - avoids measurement offset or saturation in precision op-amp front ends. |
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 (vs. axial 1.5KE), higher VC (219 V @ 2.7 A) | Better suited for space-constrained PCBs but cannot replace 1.5KE130CAHE3_B/C in high-energy surge zones | Select when board area is critical and surge threat level is ≤600 W; not drop-in for 1500 W requirements |
| 1.5KE130CAHE3_A | Same electrical specs, identical package, but earlier revision code (A vs. B/C); no functional difference | Identical use cases; differs only in manufacturing lot traceability and internal process control version | Acceptable interchange if BOM allows revision flexibility; B/C includes updated whisker test compliance (JESD 201 Class 2) |
Compared with SMBJ130CA and 1.5KE130CAHE3_A, the 1.5KE130CAHE3_B/C uniquely combines 1500 W surge handling, AEC-Q101 qualification, and axial-leaded thermal robustness - making it irreplaceable in high-reliability industrial power stages and automotive under-hood locations where sustained thermal dissipation matters.

FAQ
What is the clamping voltage of the 1.5KE130CAHE3_B/C under a 1500 W surge?
The 1.5KE130CAHE3_B/C clamps to 179 V at its peak pulse current of 8.4 A, measured under the standardized 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet (Document Number: 88301, Rev. 09-Aug-2022) and reflects the maximum voltage seen downstream during worst-case surge events. Engineers must verify system-level margin between this clamping voltage and the absolute maximum ratings of protected components.
Is the 1.5KE130CAHE3_B/C suitable for automotive applications?
Yes - the 1.5KE130CAHE3_B/C carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay's ordering information (Note 2, Page 3). It has passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. The 1.5KE130CAHE3_B/C is deployed in automotive body control modules and power distribution units where bidirectional surge immunity and extended temperature operation (–55 °C to +175 °C) are required.
Does the 1.5KE130CAHE3_B/C have polarity markings?
No - the 1.5KE130CAHE3_B/C is a bidirectional TVS diode and carries no color band or other polarity marking. Its symmetrical structure allows installation in either orientation across AC lines, differential signal pairs, or ungrounded rails. This contrasts with unidirectional variants like 1.5KE130A, which feature a cathode band and must be oriented correctly relative to circuit ground.
What is the maximum reverse leakage current for the 1.5KE130CAHE3_B/C at its working voltage?
At its maximum steady-state working voltage (VWM = 111 V), the 1.5KE130CAHE3_B/C exhibits ≤1.0 µA reverse leakage current at TA = 25 °C. This low leakage ensures minimal power loss and signal distortion in always-on protection circuits such as 4–20 mA loops or LIN bus nodes, where even microamp-level currents could affect accuracy or bias points.
How does the thermal performance of the 1.5KE130CAHE3_B/C compare to surface-mount TVS diodes?
The 1.5KE130CAHE3_B/C offers RθJL = 15.4 °C/W (junction-to-lead), significantly lower than typical SMC/SMB packages (>30 °C/W). Its axial-leaded construction and larger epoxy body enable superior heat transfer into PCB copper pours or heatsinks - critical for applications with repetitive surges or elevated ambient temperatures. This makes the 1.5KE130CAHE3_B/C preferable over SMT alternatives in high-power industrial drives where thermal runaway risk exists.
