Product details
Overview
1.5KE130CA-E3/51 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage 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 dissipation with a 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5KE130CA-E3/51 datasheet, 1.5KE130CA-E3/51 pinout, 1.5KE130CA-E3/51 application, or 1.5KE130CA-E3/51 equivalent, this device is selected for high-energy transient suppression where bidirectional polarity, low clamping ratio (VC/VBR ≈ 1.40), and AEC-Q101-qualified variants are critical - especially in automotive power distribution, industrial I/O protection, and telecom line interface circuits.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: during transient events exceeding its standoff voltage (VWM = 111 V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
The 1.5KE130CA-E3/51 is rated for bidirectional operation only (no cathode marking), supports repetitive 0.01% duty cycle pulses, and is thermally characterized with RθJA = 75 °C/W and RθJL = 15.4 °C/W - enabling reliable operation up to TJ = 175 °C under controlled PCB layout and lead temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - defines precise avalanche onset range; ensures consistent clamping behavior across production lots |
| VWM | 111 V - maximum continuous reverse working voltage; sets safe operating margin below breakdown |
| VC @ IPPM | 179 V at 8.4 A - clamping voltage under 10/1000 µs surge; determines protected circuit's peak stress level |
| PPPM | 1500 W - peak pulse power handling; enables protection against high-energy transients like ISO 7637-2 Pulse 5a |
| IPPM | 8.4 A - peak pulse current capacity; defines minimum trace width and fuse coordination requirements |
| TJ max. | 175 °C - maximum junction temperature; supports operation in under-hood automotive or industrial enclosures |
| Package | DO-201AD (Case Style 1.5KE) - axial-leaded, through-hole package with 0.375" lead length; compatible with standard wave-solder processes |
Pinout & Package
1.5KE130CA-E3/51 uses a DO-201AD (Case Style 1.5KE) axial-leaded package with no polarity marking - consistent with bidirectional TVS construction. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and rated for solder dip at 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (during positive half-cycle) | Connects to protected line; forms symmetrical conduction path with cathode during bidirectional clamping |
| Cathode | Transient current sink (during negative half-cycle) | Electrically identical to anode in bidirectional configuration; no color band or marking distinguishes terminals |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables single-device protection against severe transients such as IEC 61000-4-5 Level 4 (4 kV, 2 Ω source) |
| Clamping ratio VC/VBR ≈ 1.40 | Minimizes voltage overshoot during clamping - critical for protecting 130 V-rated bus systems |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage performance under thermal cycling |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test; suitable for commercial-grade high-reliability applications |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial surge protection systems requiring safety certification |

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/VBR ratio (~1.45) | Preferred for space-constrained PCBs; unsuitable for >1 kV surge testing or high-current line protection | Select when board area is limited and surge energy is ≤600 W; verify thermal relief for SMB footprint |
| 1.5KE130A-E3/51 | Unidirectional version; includes cathode band; identical VBR, VC, and PPPM; same DO-201AD package | Required where polarity-sensitive clamping is needed (e.g., DC rail with defined ground reference) | Choose for unidirectional DC systems; avoid in AC-coupled or floating signal paths |
Compared with SMBJ130CA and 1.5KE130A-E3/51, the 1.5KE130CA-E3/51 uniquely delivers bidirectional 1500 W surge immunity in a through-hole package - making it optimal for high-energy, polarity-agnostic protection where mechanical robustness and legacy assembly compatibility are required.

FAQ
What is the breakdown voltage tolerance for 1.5KE130CA-E3/51?
The 1.5KE130CA-E3/51 has a specified breakdown voltage range of 124 V to 137 V at 1.0 mA test current (VBR min/max). This ±5.4% tolerance ensures predictable clamping onset while accommodating process variation - critical for coordinating with downstream overvoltage lockout thresholds in protected circuits. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet.
Is 1.5KE130CA-E3/51 RoHS compliant and lead-free?
Yes, the 1.5KE130CA-E3/51 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and exemption 7a. Its matte tin-plated leads meet JESD 201 Class 1A whisker resistance, and the molding compound satisfies UL 94 V-0 flammability. No lead or other restricted substances exceed threshold limits, and the part is qualified for commercial-grade applications.
Can 1.5KE130CA-E3/51 be used in automotive applications?
The 1.5KE130CA-E3/51 is rated for operation from –55 °C to +175 °C and meets UL 497B for telecom safety, but it is not AEC-Q101 qualified. For automotive use, Vishay offers the HE3 variant (e.g., 1.5KE130CAHE3_B); the standard 1.5KE130CA-E3/51 is suitable for non-safety-critical aftermarket or industrial-automotive hybrid systems where qualification is not mandated.
What is the maximum clamping voltage of 1.5KE130CA-E3/51 under surge conditions?
The 1.5KE130CA-E3/51 exhibits a maximum clamping voltage (VC) of 179 V when subjected to its rated 8.4 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed per datasheet Table on page 2 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does the bidirectional nature of 1.5KE130CA-E3/51 affect PCB layout?
Because 1.5KE130CA-E3/51 is bidirectional, it has no polarity marking - both leads are functionally identical. PCB layout requires symmetric placement with equal trace lengths and impedance to ground on both sides; no cathode orientation check is needed. This simplifies routing in AC-coupled or floating signal paths but mandates careful coordination with upstream protection devices to avoid unintended conduction paths.
