Product details
Overview
1V5KE62A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 58.9V minimum breakdown voltage (VBR), 53.0V reverse stand-off voltage (VRWM), and 85.0V clamping voltage (VC) at 17.7A peak pulse current. It protects power rails and I/O lines against ESD, lightning surges, and inductive switching transients in industrial power supplies and automotive ECUs.
For engineers reviewing the 1V5KE62A datasheet, 1V5KE62A pinout, 1V5KE62A application, or 1V5KE62A equivalent, key selection criteria include its 1ms 1500W peak pulse rating, low 175°C maximum junction temperature, glass-passivated junction for reliability, and compliance with RoHS and halogen-free standards per IEC 61249-2-21.
Technical Context
The 1V5KE62A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds VRWM = 53.0V and fully clamps at VC = 85.0V under 17.7A (10/1000μs waveform). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1μA above 10V).
Designed for single-pulse surge immunity, it supports 200A non-repetitive forward surge current (IFSM) and exhibits fast response time (<1ns), low incremental surge resistance, and thermal stability across –55°C to +175°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 53.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 58.9 V @ 1 mA - Guaranteed avalanche initiation threshold under specified test current |
| VC | 85.0 V @ 17.7 A - Clamped voltage during 10/1000μs surge, limiting downstream stress |
| PPPM | 1500 W - Peak pulse power handling capability at 1 ms pulse width |
| IR (max) | <1 μA @ 10 V - Ultra-low reverse leakage preserves signal integrity and standby power |
| TJ (max) | +175 °C - High junction temperature rating enables operation in under-hood or high-power environments |
| Package | DO-201 - Industry-standard axial-leaded package with tin-plated leads, UL 94V-0 molding |
Pinout & Package
DO-201 package: axial-leaded, cylindrical body with cathode band marking polarity. Leads are pure tin-plated, solderable per J-STD-002; weight ≈ 0.090 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Lower PPPM (600W), SMC package, VRWM = 58.0V, VC = 93.6V @ 6.4A | Less robust for high-energy 1ms surges; better suited for space-constrained PCBs | Select SMBJ58A only if board area is critical and surge energy is ≤600W |
| 1N6290A | Same manufacturer, identical electrical specs and DO-201 package; JEDEC-registered part number | No functional difference; used interchangeably in legacy designs and BOMs | 1N6290A is a direct JEDEC-compliant alternative with identical performance and sourcing |
Compared with SMBJ58A and 1N6290A, the 1V5KE62A offers higher surge robustness (1500W vs. 600W) and tighter clamping (85.0V vs. 93.6V), while 1N6290A provides full form-fit-function equivalence with JEDEC standardization for procurement traceability.

FAQ
What is the breakdown voltage range for 1V5KE62A?
The 1V5KE62A has a guaranteed breakdown voltage (VBR) range of 58.9V to 65.1V at 1mA test current, per Taiwan Semiconductor's D2112 specification sheet. This ensures consistent clamping behavior across production lots and supports reliable design margining against overvoltage events.
Is 1V5KE62A unidirectional or bidirectional?
The 1V5KE62A is a unidirectional TVS diode, indicated by the absence of "C" suffix in its marking and confirmed by its asymmetric electrical specifications (e.g., VRWM = 53.0V, no bidirectional VRWM value listed). It conducts only in reverse avalanche mode and must be oriented with cathode toward the protected line.
What is the maximum clamping voltage of 1V5KE62A under surge conditions?
The 1V5KE62A clamps to a maximum of 85.0V at 17.7A peak pulse current (10/1000μs waveform), as specified in the Electrical Characteristics table. This VC value defines the upper voltage limit imposed on protected circuitry during standardized surge testing.
Does 1V5KE62A meet RoHS and halogen-free requirements?
Yes, the 1V5KE62A is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the official Taiwan Semiconductor datasheet (Version D2112). This makes it suitable for export to EU, China, and other regulated markets.
What package type does 1V5KE62A use and what are its mechanical features?
The 1V5KE62A uses the DO-201 axial package with pure tin-plated leads solderable per J-STD-002, UL 94V-0 flammability-rated molding compound, and cathode band polarity marking. Its approximate weight is 0.090g, and it meets JESD 201 Class 2 whisker resistance requirements.
