Product details
Overview
1.5KE130CAHE3_A/D 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), 179 V maximum clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform. It is RoHS-compliant, AEC-Q101 qualified, and used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5KE130CAHE3_A/D datasheet, 1.5KE130CAHE3_A/D pinout, 1.5KE130CAHE3_A/D application, or 1.5KE130CAHE3_A/D equivalent, this device serves as a robust, unidirectional/bidirectional transient suppressor with verified clamping performance, thermal stability up to +175 °C junction temperature, and JEDEC-standard 1.5KE package compatibility - critical for automotive, industrial, and telecom front-end protection design.
Technical Context
This TVS diode operates bidirectionally with symmetrical breakdown characteristics in both polarities, enabling use across AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, directly supporting fast (<1 ns) response to ESD and surge events per IEC 61000-4-2/4-5.
The device delivers 1500 W peak pulse power under 10/1000 µs waveform with derating above 25 °C ambient, supported by RθJA = 75 °C/W and RθJL = 15.4 °C/W thermal metrics. Its 111 V stand-off voltage (VWM) and ≤1.0 µA reverse leakage at VWM ensure minimal standby loading on protected circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient 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) | Not suitable for 1500 W surge events; limited to board-level secondary protection | Select when space-constrained PCB layout requires SMT and surge levels are ≤600 W |
| 1.5KE130CA | Same electrical specs but commercial-grade (non-AEC-Q101), E3 suffix only (no HE3) | Lacks automotive qualification; not approved for under-hood or safety-critical modules | Select for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated |
Compared with 1.5KE130CAHE3_A/D, SMBJ130CA trades peak power and ruggedness for compactness, while 1.5KE130CA retains identical clamping behavior but omits automotive qualification - making the HE3 variant the sole choice for production automotive designs requiring traceable AEC-Q101 validation.

FAQ
What is the breakdown voltage range of the 1.5KE130CAHE3_A/D?
The 1.5KE130CAHE3_A/D has a guaranteed breakdown voltage range of 124 V to 137 V at 1.0 mA test current (IT), per Vishay's 88301 datasheet. This ±5 % tolerance ensures predictable clamping onset and allows designers to verify margin between VWM (111 V) and minimum VBR in their system-level overvoltage protection scheme. The 1.5KE130CAHE3_A/D maintains this specification across -55 °C to +175 °C junction temperature.
Is the 1.5KE130CAHE3_A/D suitable for automotive applications?
Yes, the 1.5KE130CAHE3_A/D is AEC-Q101 qualified per Vishay documentation (note 2 on page 3 of document 88301), covering stress tests including temperature cycling, high-temperature reverse bias, and surge endurance. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and RoHS requirements - making the 1.5KE130CAHE3_A/D appropriate for engine control, body electronics, and ADAS subsystems where automotive-grade reliability is mandatory.
What is the maximum clamping voltage of the 1.5KE130CAHE3_A/D and at what current is it specified?
The 1.5KE130CAHE3_A/D has a maximum clamping voltage (VC) of 179 V, measured at its peak pulse current (IPPM) of 8.4 A using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is critical for ensuring downstream components remain within their absolute maximum ratings. The 1.5KE130CAHE3_A/D achieves this with low incremental surge resistance, minimizing overshoot.
Does the 1.5KE130CAHE3_A/D have polarity markings on its package?
No, the 1.5KE130CAHE3_A/D does not feature polarity markings such as a cathode band because it is a bidirectional TVS diode. Its internal structure consists of two opposing avalanche junctions, resulting in symmetrical clamping behavior in both directions. This eliminates orientation dependency during PCB assembly and enables direct use in AC-coupled or floating signal paths - a key distinction from unidirectional variants like 1.5KE130AHE3_A/D, which do include a cathode band.
What is the thermal resistance of the 1.5KE130CAHE3_A/D and how does it affect power dissipation?
The 1.5KE130CAHE3_A/D has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15.4 °C/W. These values govern steady-state power handling: at 25 °C ambient, its 6.5 W continuous power dissipation (PD) derates linearly above that temperature, reaching zero at ~120 °C ambient. For surge conditions, the low RθJL enables efficient heat transfer to PCB copper or heatsinks, preserving the 1500 W pulse rating during repetitive events.
