Overview
1.5KE130CAHE3/51 from Vishay General Semiconductor is a bi-directional 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 at IT = 1 mA), 179 V maximum clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the 1.5KE130CAHE3/51 datasheet, 1.5KE130CAHE3/51 pinout, 1.5KE130CAHE3/51 application, or 1.5KE130CAHE3/51 equivalent, this device offers AEC-Q101 qualification, RoHS-compliant HE3 packaging, bi-directional clamping symmetry, low incremental surge resistance, and fast sub-nanosecond response time - critical for lightning-induced transient suppression in telecom and automotive ECUs.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at VWM = 111 V), while the molded epoxy case meets UL 94 V-0 flammability rating.
The device delivers 1500 W peak pulse power handling under standardized 10/1000 µs transients, with thermal resistance of RθJA = 75 °C/W and RθJL = 15.4 °C/W - enabling reliable operation up to TJ = +175 °C. It supports repetitive surge duty cycles ≤ 0.01% and complies with JESD 201 Class 2 whisker testing.
Key Specifications

FAQ
What does the "CA" suffix indicate in 1.5KE130CAHE3/51?
The "CA" suffix in 1.5KE130CAHE3/51 denotes a bi-directional configuration - meaning the device clamps voltage transients equally in both polarities, with identical breakdown and clamping characteristics in forward and reverse directions. This eliminates polarity-dependent installation errors and simplifies layout for AC-coupled or floating signal lines. The 1.5KE130CAHE3/51 has no color band or marking, confirming its symmetrical construction.
Is 1.5KE130CAHE3/51 qualified for automotive applications?
Yes, 1.5KE130CAHE3/51 is AEC-Q101 qualified, as confirmed in Vishay's datasheet revision 11-Oct-16 (Document Number: 88301). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive electronics such as engine control modules and ADAS power supplies.
What is the maximum clamping voltage of 1.5KE130CAHE3/51 and at what current is it specified?
The maximum clamping voltage (VC) of 1.5KE130CAHE3/51 is 179 V, measured at a peak pulse current (IPPM) of 8.4 A using the standard 10/1000 µs waveform. This value represents the worst-case voltage seen by downstream circuitry during a full-rated 1500 W transient event - critical for ensuring compatibility with 200 V-rated capacitors and 175 V MOSFETs in protected circuits.
How does the HE3 suffix differ from E3 in Vishay's 1.5KE part numbering?
The HE3 suffix in 1.5KE130CAHE3/51 indicates RoHS compliance plus AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance only (commercial grade). The HE3 variant undergoes additional automotive-specific reliability testing and uses enhanced plating - making 1.5KE130CAHE3/51 appropriate for automotive Tier 1 suppliers, unlike the E3-only 1.5KE130CA-E3/54.
Can 1.5KE130CAHE3/51 be used in parallel to increase surge current handling?
Yes, 1.5KE130CAHE3/51 can be paralleled to increase total peak pulse current capacity, but only with careful attention to matching - devices must be from the same manufacturing lot to ensure balanced current sharing due to VBR tolerance (±5%). Unmatched units may cause thermal runaway; Vishay recommends using a single higher-power device (e.g., 3KP130CA) instead unless layout constraints require parallel placement.
