Product details
Overview
1V5KE62CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 58.9–65.1 V at 1 mA, clamping voltage 85.0 V at 17.7 A peak pulse current, and reverse stand-off voltage 53.0 V. It protects power rails and signal lines in industrial power supplies, motor drives, and telecom interfaces against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE62CA datasheet, 1V5KE62CA pinout, 1V5KE62CA application, or 1V5KE62CA equivalent, key selection criteria include bidirectional clamping performance, 1 ms surge rating, DO-201 mechanical compatibility, junction temperature range (−55°C to +175°C), and compliance with IEC 61000-4-2/4-4/4-5 immunity standards.
Technical Context
The 1V5KE62CA operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its low incremental surge resistance ensures stable voltage limiting during fast transients, while sub-1 µA leakage above 10 V supports low-power standby integrity.
Designed for unclamped inductive switching and electrical fast transient (EFT) protection, the device meets JEDEC JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Its 1 ms pulse waveform rating aligns with IEC 61000-4-5 Level 4 surge testing (4 kV line-to-earth).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W at 1 ms - sustains high-energy surges without thermal runaway |
| Breakdown Voltage VBR | 58.9–65.1 V @ 1 mA - defines minimum clamping onset threshold |
| Clamping Voltage VC | 85.0 V @ 17.7 A - maximum voltage seen by protected circuit during worst-case surge |
| Reverse Stand-off Voltage VRWM | 53.0 V - maximum continuous operating voltage before leakage rises significantly |
| Junction Temperature Range | −55°C to +175°C - enables deployment in under-hood automotive or industrial enclosures |
| Package | DO-201 - industry-standard axial leaded package with 0.090 g mass and tin-plated leads |
| Leakage Current IR | <1 µA @ VRWM - preserves low-power system sleep modes |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking for unidirectional variants; for 1V5KE62CA (bidirectional), polarity is non-directional - terminals are interchangeable. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional polarity - either terminal may connect to line or ground |
| Lead 1 / Lead 2 | Surge current path | Carries full IPPM (17.7 A) during 10/1000 µs transient without bond wire failure |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability and stable VBR over 1000+ surge events |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 4 kV surge on 2 Ω source impedance |
| Low incremental surge resistance | Minimizes voltage overshoot during rapid di/dt transients (e.g., relay coil de-energization) |
| RoHS & halogen-free compliance | Fulfills IPC-1752A material declaration and EU Directive 2011/65/EU requirements |
| Fast response time <1 ns | Activates before MOSFET gate oxide or MCU I/O structures experience damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | 600 W rating, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 | Select when space-constrained PCB layout prioritizes size over 1500 W capability |
| 1N6290A | Same die, identical specs - JEDEC registered part number for same device | No functional difference; used interchangeably in legacy designs | Preferred for designs requiring JEDEC-standardized nomenclature and traceability |
Compared with SMBJ58CA and 1N6290A, the 1V5KE62CA offers higher surge robustness in DO-201 form factor, enabling direct replacement of older 1N6290A while providing superior thermal dissipation versus surface-mount SMBJ58CA in high-reliability industrial systems.

FAQ
What is the clamping voltage of the 1V5KE62CA under standard test conditions?
The 1V5KE62CA has a maximum clamping voltage (VC) of 85.0 V at 17.7 A peak pulse current (IPPM), measured using a 10/1000 µs double-exponential waveform. This value is guaranteed per the manufacturer's electrical specifications table and defines the upper voltage limit imposed on protected circuits during surge events. The 1V5KE62CA maintains this clamping performance across its full operating temperature range (−55°C to +175°C).
Is the 1V5KE62CA unidirectional or bidirectional, and how does that affect circuit placement?
The 1V5KE62CA is a bidirectional TVS diode, indicated by the "CA" suffix and confirmed by symmetric breakdown voltage (58.9–65.1 V) in both polarities. Unlike unidirectional variants, it requires no polarity orientation during placement - either lead connects to line or ground. This simplifies layout in AC-coupled or floating systems such as RS-485 buses or isolated DC-DC feedback paths, where polarity reversal is possible.
What is the maximum continuous reverse voltage the 1V5KE62CA can withstand without significant leakage?
The 1V5KE62CA has a reverse stand-off voltage (VRWM) of 53.0 V - the highest DC or RMS voltage it can block continuously while maintaining leakage current below 5 µA. Operating above this voltage risks premature conduction and thermal instability. Designers must ensure normal operating voltages (e.g., 48 V telecom rails) remain at least 10% below VRWM to accommodate ripple and tolerance margins, preserving long-term reliability of the 1V5KE62CA.
Does the 1V5KE62CA meet RoHS and halogen-free requirements?
Yes, the 1V5KE62CA is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These attributes are verified in TSC's material declarations and support compliance with environmental directives in EU, China, and South Korea markets - critical for industrial equipment certified to CE or CCC marks.
Can the 1V5KE62CA be used in place of the JEDEC-standard 1N6290A?
Yes, the 1V5KE62CA is functionally and electrically identical to the JEDEC-standard 1N6290A - same breakdown voltage, clamping behavior, package (DO-201), and surge rating. TSC explicitly lists 1N6290A as the JEDEC type number for 1V5KE62CA in its datasheet. No PCB or schematic changes are needed when substituting 1V5KE62CA for 1N6290A, and the 1V5KE62CA retains full compatibility with existing 1N6290A qualification data.
