Product details
Overview
1.5KE130CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on power and signal lines. It features a 130 V breakdown voltage (VBR = 124–137 V), 1500 W peak pulse power (10/1000 µs), 179 V maximum clamping voltage at rated current, 1.0 mA test current, and operates across –55 °C to +175 °C junction temperature range. It protects MOSFETs and ICs in industrial power supplies and automotive sensor interfaces.
For engineers reviewing the 1.5KE130CA-E3/54 datasheet, 1.5KE130CA-E3/54 pinout, 1.5KE130CA-E3/54 application, or 1.5KE130CA-E3/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal derating curves, RoHS-compliant packaging (E3 suffix), and AEC-Q101-qualified alternatives - all critical for surge protection design validation and BOM selection.
Technical Context
This device uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating circuits without polarity sensitivity, unlike unidirectional TVS diodes requiring cathode orientation.
Rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01 % duty cycle, it sustains repetitive surges when thermally managed per its RθJA = 75 °C/W and RθJL = 15.4 °C/W thermal resistances. Stand-off voltage is 111 V, reverse leakage ≤1.0 µA at VWM, and clamping occurs at 179 V @ 8.4 A IPPM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 111 V - maximum continuous working voltage before significant leakage begins; sets safe margin below breakdown |
| VC @ IPPM | 179 V - clamped voltage during 8.4 A 10/1000 µs surge; defines worst-case stress on protected downstream circuitry |
| PPPM | 1500 W - peak transient energy absorption capacity; supports high-energy lightning or inductive-switching events |
| IPPM | 8.4 A - maximum non-repetitive surge current the device safely clamps without degradation |
| TJ Range | –55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with matte tin-plated leads, UL 94 V-0 molding compound |
Pinout & Package
1.5KE130CA-E3/54 is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package. Bidirectional construction means no polarity marking; both leads are electrically symmetric and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Either lead serves as input/output node; clamping occurs identically in both directions during overvoltage events |
| Leads (matte tin plated) | Thermal and electrical interface | Supports J-STD-002 solderability and 275 °C/10 s solder dip; provides primary heat path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Handles high-energy transients common in 24 V/48 V industrial control systems and automotive battery line surges |
| Sub-nanosecond response time | Clamps before sensitive ICs experience damaging overvoltage - critical for protecting microcontrollers and CAN transceivers |
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness (for HE3 variants) |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for lead-free reflow and high-reliability commercial applications |

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 peak power (600 W), smaller SMB package (vs. DO-201AD), higher VC (219 V @ 2.7 A) | Better suited for space-constrained PCBs but requires derating in high-energy surge environments | Select when board area is critical and surge threat level is moderate (e.g., consumer USB ports) |
| 1.5KE130CAHE3_B | Identical electrical specs; AEC-Q101 qualified, HE3 whisker rating (Class 2), revision-coded "B" lot traceability | Required for automotive production programs needing PPAP documentation and extended reliability validation | Choose for Tier-1 automotive designs where qualification evidence and lifecycle continuity are mandatory |
Compared with 1.5KE130CA-E3/54, SMBJ130CA trades peak power and thermal mass for compactness, while 1.5KE130CAHE3_B adds automotive qualification without altering clamping performance - enabling direct use in validated production lines where compliance evidence is required.

FAQ
What is the breakdown voltage tolerance for 1.5KE130CA-E3/54?
The 1.5KE130CA-E3/54 has a specified breakdown voltage range of 124 V to 137 V at 1.0 mA test current (IT). This ±5.4 % tolerance ensures consistent clamping behavior across production lots while allowing margin for temperature drift and aging. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is 1.5KE130CA-E3/54 suitable for automotive applications?
The 1.5KE130CA-E3/54 is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified. For automotive use, select the 1.5KE130CAHE3_B variant, which carries full AEC-Q101 certification including temperature cycling, HTRB, and ESD testing. The 1.5KE130CA-E3/54 may be used in non-safety-critical aftermarket or prototyping contexts but lacks formal automotive qualification.
What is the maximum clamping voltage of 1.5KE130CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE130CA-E3/54 is 179 V, measured at its rated peak pulse current (IPPM) of 8.4 A using a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range.
How does the bidirectional configuration of 1.5KE130CA-E3/54 affect PCB layout?
The bidirectional configuration of 1.5KE130CA-E3/54 eliminates polarity constraints: either lead can connect to line or ground, simplifying layout and reducing assembly errors. Unlike unidirectional TVS diodes, no band marking exists - the DO-201AD package is symmetric, enabling placement flexibility in AC-coupled or floating signal paths without orientation verification.
What thermal derating applies to 1.5KE130CA-E3/54 above 25 °C ambient?
1.5KE130CA-E3/54 follows a linear derating curve starting at 25 °C: power dissipation drops from 6.5 W at TL = 75 °C, with full derating to zero at 175 °C junction temperature. Its RθJA = 75 °C/W and RθJL = 15.4 °C/W define thermal limits; PCB copper area and lead length directly impact achievable power handling in real-world layouts.
