Product details
Overview
1V5KE130A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 124V minimum breakdown voltage (VBR), 111V reverse stand-off voltage (VRWM), and 179V clamping voltage (VC) at 8.4A peak pulse current. It protects power rails and I/O lines in industrial motor drives against ESD and inductive switching transients.
For engineers reviewing the 1V5KE130A datasheet, 1V5KE130A pinout, 1V5KE130A application, or 1V5KE130A equivalent, key selection criteria include its 179V clamping performance at 8.4A, 111V working voltage margin for 100V DC bus systems, low 5μA leakage at VRWM, and UL 94V-0 molded case for high-reliability PCB mounting.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of 10/1000μs waveform transients. Its unidirectional polarity provides asymmetric protection ideal for DC-biased signal or power lines.
The device operates across –55°C to +175°C junction temperature range and sustains 200A non-repetitive forward surge current (8.3ms half-sine), making it suitable for high-energy inductive load switching in industrial controls and power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 111 V - Maximum continuous reverse operating voltage before significant leakage begins; sets usable DC rail margin. |
| VBR min/max | 124 V / 137 V - Breakdown occurs within this band at 1 mA test current; defines turn-on threshold tolerance. |
| VC @ IPPM | 179 V - Clamped voltage during 8.4 A 10/1000μs transient; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling at 1 ms pulse width; certifies robustness against IEC 61000-4-5 Level 4 surges. |
| IR @ VRWM | <5 μA - Reverse leakage at rated stand-off voltage; ensures minimal standby power loss in battery-powered systems. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in enclosed enclosures or near heat sources. |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with pure tin-plated leads (J-STD-002 compliant), UL 94V-0 molding compound, and cathode band marking for polarity identification. Weight: 0.090 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration. |
| Cathode | Reverse-biased terminal | Connected to protected line (e.g., 100V DC rail); conducts only during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity stress. |
| 1500W peak pulse power (1 ms) | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment up to Level 4 (4 kV line-to-line). |
| Clamping ratio VC/VBR ≈ 1.44 | Indicates low dynamic impedance; delivers tighter voltage control during transient events than higher-ratio TVS devices. |
| RoHS & halogen-free compliance | Fulfills EU environmental directives and IPC/JEDEC J-STD-020 moisture sensitivity level (MSL) compatibility for lead-free reflow. |
Applications
| Industrial Motor Drive Protection | DC Power Supply Input Protection |
|---|---|
Use Scenario: Suppresses voltage spikes caused by contactor switching or regenerative braking in 100V DC bus systems. IC Role / Device Role: Unidirectional TVS placed between DC+ and chassis ground to clamp transients below MOSFET drain-source rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Lower PPPM (600W), SMC package, 110V VRWM, 177V VC @ 3.4A | Surface-mount only; insufficient for 1500W IEC 61000-4-5 Level 4 testing | Choose when space-constrained PCB layout requires SMT and surge threat level is ≤Level 2. |
| 1N6298A | Same manufacturer, identical specs and DO-201 package; obsolete JEDEC part number for 1V5KE130A | No functional difference; legacy marking used in older designs | Select 1V5KE130A for new designs to ensure supply continuity and updated manufacturing traceability. |

FAQ
What is the clamping voltage of the 1V5KE130A under standard 10/1000μs surge conditions?
The 1V5KE130A clamps to 179 V when subjected to an 8.4 A peak pulse current with a 10/1000μs waveform. This value is measured per JEDEC standards and defines the maximum voltage seen by protected circuitry during a defined transient event. The 1V5KE130A maintains this clamping performance across its full operating temperature range.
Is the 1V5KE130A suitable for bidirectional transient protection?
No-the 1V5KE130A is a unidirectional TVS diode and must be used with correct polarity (cathode to protected line). For bidirectional protection, the variant 1V5KE130CA is required. The 1V5KE130A lacks symmetrical breakdown characteristics and will conduct heavily in reverse bias beyond its VRWM, potentially failing catastrophically if misapplied.
What is the maximum junction temperature rating for the 1V5KE130A?
The 1V5KE130A has a maximum junction temperature (TJ) rating of +175°C, allowing reliable operation in high-ambient environments such as enclosed motor drive cabinets or near power transformers. Derating curves confirm ≥5 W steady-state power dissipation at 75°C ambient with 0.375-inch lead length.
How does the 1V5KE130A compare to the older 1N6298A part number?
The 1V5KE130A is the current production replacement for the obsolete 1N6298A, sharing identical electrical specifications, DO-201 package, and marking conventions. Taiwan Semiconductor transitioned to the 1V5KE prefix for improved traceability and process control; no design changes or performance differences exist between 1V5KE130A and 1N6298A.
What packaging options are available for the 1V5KE130A?
The 1V5KE130A is supplied in two standard configurations: 1,250 pieces per tape-and-reel (for automated assembly) and 500 pieces per ammo box (for manual or low-volume prototyping). Both use DO-201 axial-leaded packaging with green molding compound and cathode band polarity marking per TSC specification D2112.
