Product details
Overview
1V5KE82A from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with breakdown voltage 77.9–86.1 V at 1 mA, reverse stand-off voltage 70.1 V, clamping voltage 113 V at 13.3 A, and junction temperature range −55 °C to +175 °C. It protects power rails and I/O lines in industrial motor drives, AC/DC power supplies, and telecom interface circuits against ESD and lightning-induced surges.
For engineers reviewing the 1V5KE82A datasheet, 1V5KE82A pinout, 1V5KE82A application, or 1V5KE82A equivalent, key selection criteria include its 113 V clamping voltage at 13.3 A peak pulse current, 70.1 V maximum reverse stand-off voltage, DO-201 mechanical outline, unidirectional polarity marking, and compliance with JEDEC JESD201 Class 2 whisker testing.
Technical Context
The 1V5KE82A operates as a silicon avalanche diode, triggered when transient voltage exceeds its reverse stand-off threshold of 70.1 V. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, and low incremental surge resistance enables effective energy diversion during 10/1000 µs waveform transients.
Designed for single-polarity protection, it exhibits typical reverse leakage <1 µA above 10 V and supports peak forward surge current up to 200 A (8.3 ms half-sine). Thermal performance is rated for 5 W continuous power dissipation at 75 °C lead temperature, with full derating to zero at 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 70.1 V - Maximum DC or continuous AC reverse voltage before significant leakage begins |
| VBR @ IT=1 mA | 77.9–86.1 V - Breakdown voltage range defining reliable avalanche onset under standardized test current |
| VC @ IPPM=13.3 A | 113 V - Clamping voltage limiting protected circuit voltage during worst-case 1500 W surge event |
| PPPM | 1500 W - Peak pulse power handling capability per 1 ms waveform, defining surge energy absorption capacity |
| TJ Range | −55 °C to +175 °C - Operating junction temperature range supporting industrial and automotive under-hood environments |
| IR @ VRWM | <1 µA - Low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Package | DO-201 - Standard axial-leaded through-hole package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
1V5KE82A uses the DO-201 package: axial-leaded, cylindrical epoxy-molded body with cathode band marking for unidirectional polarity. Leads are pure tin-plated, RoHS-compliant, and meet UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower potential node; defines current path during reverse-biased clamping |
| Cathode (banded end) | High-side connection point | Connected to protected line; avalanche conduction occurs when voltage at cathode exceeds VRWM relative to anode |
Key Features

|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche characteristics over lifetime and thermal cycling |
| 1500 W peak pulse power (1 ms) | Supports robust protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge events |
| Clamping ratio VC/VBR ≈ 1.34 | Indicates tight voltage control during conduction-lower ratio improves system margin |
| Fast response time <1 ps | Enables suppression of ESD transients (IEC 61000-4-2) before downstream IC damage occurs |
| RoHS and halogen-free | Complies with environmental regulations including IEC 61249-2-21 for printed wiring board assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | Lower peak power (600 W), smaller SMB package, VRWM = 80 V, VC = 130 V @ 4.6 A | Not suitable for 1500 W surge requirements; limited to lower-energy IEC 61000-4-5 Level 2 events | Select only where space constraints outweigh surge energy needs and clamping voltage margin allows |
| 1N6293A | Same manufacturer, identical electrical specs and DO-201 package; obsolete JEDEC prefix vs. TSC's 1V5KE82A branding | No functional or layout difference; direct second-source part within same product family | Preferred for legacy design continuity or dual-sourcing programs requiring identical form-fit-function |
Compared with SMBJ80A and 1N6293A, the 1V5KE82A delivers higher surge robustness (1500 W vs. 600 W) and tighter clamping (113 V vs. 130 V), while 1N6293A offers identical performance with JEDEC-standardized marking-making 1V5KE82A optimal for new designs needing certified high-energy protection.

FAQ
What is the maximum clamping voltage of the 1V5KE82A under a 1500 W surge?
The 1V5KE82A clamps to 113 V at 13.3 A peak pulse current, corresponding to a 1500 W surge per the standard 10/1000 µs waveform. This value is measured and guaranteed per the manufacturer's electrical specifications table and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 1V5KE82A unidirectional or bidirectional?
The 1V5KE82A is a unidirectional TVS diode, indicated by the absence of "C" suffix in its marking and confirmed by its specified reverse stand-off voltage (70.1 V) and breakdown voltage range (77.9–86.1 V). It conducts only when cathode voltage exceeds anode voltage by more than VRWM, making it suitable for DC rail protection with defined polarity.
What package type does the 1V5KE82A use, and is it lead-free?
The 1V5KE82A uses the DO-201 axial-leaded package with pure tin-plated leads, fully compliant with RoHS and J-STD-002 solderability standards. The molding compound meets UL 94V-0 flammability rating, and the device is halogen-free per IEC 61249-2-21-ensuring compatibility with lead-free reflow and wave soldering processes.
Can the 1V5KE82A replace the 1N6293A in existing designs?
Yes-the 1V5KE82A is functionally and physically identical to 1N6293A, sharing the same DO-201 package, electrical parameters (VBR, VRWM, VC, PPPM), and thermal ratings. Taiwan Semiconductor lists both as members of the same product family, enabling drop-in replacement without PCB or schematic changes in legacy or dual-sourced applications.
What is the junction temperature rating for continuous operation of the 1V5KE82A?
The 1V5KE82A has a maximum junction temperature of +175 °C and a minimum of −55 °C. For continuous operation, its power dissipation is rated at 5 W with 0.375 inch lead length at ambient temperature of 75 °C, derating linearly to zero at 175 °C-supporting use in high-temperature industrial enclosures and under-hood automotive locations.
