Product details
Overview
1.5KE130 from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage VBR = 117–143 V at IT = 1.0 mA, clamping voltage VC = 187 V at IPP = 8.4 A (10/1000 µs), and working stand-off voltage VWM = 105 V - designed for automotive ECU power rail protection against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE130 datasheet, 1.5KE130 pinout, 1.5KE130 application, or 1.5KE130 equivalent, key selection criteria include its 187 V clamping performance at 8.4 A surge, DO-201 mechanical compatibility with high-reliability PCB layouts, AEC-Q101 qualification status (via 1.5KE130A variant), and compliance with ISO 7637-2 immunity requirements for 12 V automotive systems.
Technical Context
The 1.5KE130 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 117–143 V breakdown range. It delivers 1500 W peak pulse power handling per 10/1000 µs waveform and exhibits low dynamic impedance to limit transient overvoltage during fast-rising events.
Its junction temperature range spans −55 °C to +175 °C, enabling deployment in under-hood automotive environments. The device features pure tin-plated leads compliant with J-STD-002 solderability and meets JESD 201 Class 2 whisker resistance, supporting long-term reliability in thermally stressed applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0 mA | 117–143 V - defines precise avalanche initiation threshold for accurate overvoltage triggering |
| VWM | 105 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP = 8.4 A | 187 V - clamped voltage during full 1500 W surge, limiting downstream IC stress |
| PPK | 1500 W - peak pulse power rating at TA = 25 °C, derated above ambient per Fig.2 |
| IPP (10/1000 µs) | 8.4 A - maximum non-repetitive surge current the device safely clamps without failure |
| TJ max | +175 °C - enables operation in high-temperature engine bay locations without thermal shutdown |
| Package | DO-201 - industry-standard axial leaded package with 0.090 g mass and UL 94V-0 molding compound |
Pinout & Package
DO-201 package: axial-leaded, cylindrical glass-passivated body with cathode band marking; leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker test requirements. Polarity is marked by a single band indicating cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to system ground or low-side reference; carries full surge current during transient suppression |
| Cathode | Reverse-biased input / high-voltage transient entry point | Connected to protected line (e.g., battery rail); avalanche breakdown initiates here when VREV > VBR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | DO-214AA package, 600 W rating, VC = 211 V @ 5.3 A, lower surge capacity | Surface-mount only; unsuitable for through-hole designs or 1500 W-level transients | Select when board space constraints require SMD and surge energy is ≤ 600 W |
| 1N6298A | Same family, tighter VBR tolerance (124–137 V), identical DO-201 package and 187 V clamping | Direct functional replacement with improved consistency; AEC-Q101 qualified | Prefer for new automotive designs requiring qualification evidence and tighter parametric control |
Compared with 1.5KE130, SMBJ130A offers smaller footprint but sacrifices 60% peak power handling and raises clamping voltage, while 1N6298A delivers identical protection performance with tighter VBR spread and formal AEC-Q101 validation - making it the preferred upgrade for safety-critical deployments.

FAQ
What is the clamping voltage of the 1.5KE130 under standard 10/1000 µs surge conditions?
The 1.5KE130 clamps to a maximum of 187 V when subjected to an 8.4 A peak impulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures protected circuitry remains below critical overvoltage thresholds during load dump or inductive switching events. The 1.5KE130 achieves this performance while maintaining low dynamic impedance and sub-nanosecond response time.
Is the 1.5KE130 suitable for automotive applications requiring AEC-Q101 qualification?
The base 1.5KE130 is not AEC-Q101 qualified; however, its direct variant 1.5KE130A (JEDEC type 1N6298A) is fully AEC-Q101 certified. Engineers specifying 1.5KE130 for automotive use should select the 'A' suffix version to meet qualification requirements. Both share identical electrical parameters including VBR, VC, and PPK, but only 1.5KE130A carries formal stress-test validation per AEC-Q101.
How does the 1.5KE130 differ from the SMBJ130A in terms of physical implementation and surge handling?
The 1.5KE130 uses a DO-201 axial package with through-hole mounting, whereas SMBJ130A uses DO-214AA surface-mount packaging. Electrically, 1.5KE130 handles 1500 W at 8.4 A with 187 V clamping, while SMBJ130A is rated for 600 W at 5.3 A with 211 V clamping. Thus, 1.5KE130 provides higher surge margin and lower clamping voltage but requires different PCB layout and assembly processes than SMBJ130A.
What is the maximum working stand-off voltage (VWM) for the 1.5KE130, and why is it important for circuit design?
The 1.5KE130 has a VWM of 105 V, meaning it remains in high-impedance blocking mode up to this reverse voltage without significant leakage. This parameter ensures compatibility with 12 V and 24 V automotive systems where normal operating voltages must stay well below VBR to avoid false triggering. Designers use VWM to verify margin between nominal rail voltage and TVS activation threshold - critical for avoiding nuisance conduction during cranking or ripple.
Can the 1.5KE130 be used in bidirectional configurations?
No - the 1.5KE130 is strictly unidirectional and marked with a cathode band. For bidirectional protection, Taiwan Semiconductor offers the 1.5KE130CA variant (JEDEC type 1N6298CA), which features symmetrical breakdown in both polarities. Using 1.5KE130 in reverse-biased AC or floating applications risks permanent damage due to lack of forward conduction path and undefined behavior beyond VF limits.
