Product details
Overview
1.5KE82C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 82 V, working stand-off voltage 66.4 V, clamping voltage 118 V at 13 A peak pulse current, and junction temperature range −55 °C to +175 °C. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE82C datasheet, 1.5KE82C pinout, 1.5KE82C application, or 1.5KE82C equivalent, this page delivers verified electrical parameters, mechanical package data, real-world protection use cases, and qualified alternatives for ESD and inductive switching surge immunity design.
Technical Context
The 1.5KE82C operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 73.8–90.2 V breakdown range (tested at 1 mA), clamping transient energy within 1.0 ps response time. Its low dynamic impedance ensures stable clamping under 10/1000 μs surges up to 1500 W.
It meets AEC-Q101 qualification and ISO 7637-2 immunity requirements for automotive electronics, with pure tin-plated leads compliant to J-STD-002 and JEDEC DO-201 outline. Polarity is marked by cathode band; no forward conduction occurs below 3.5 V at 50 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 82 V - defines rated suppression threshold for system-level overvoltage coordination |
| Breakdown Voltage VBR @ 1 mA | 73.8–90.2 V - guaranteed avalanche initiation window under standardized test conditions |
| Working Stand-off Voltage VWM | 66.4 V - maximum continuous reverse voltage before leakage exceeds 1 µA |
| Clamping Voltage VC @ IPP = 13 A | 118 V - peak voltage seen by protected circuit during full 1500 W surge event |
| Peak Pulse Power PPK | 1500 W - non-repetitive surge handling capability per 10/1000 μs waveform |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive and high-temp industrial deployment |
| Leakage Current ID @ VWM | <1 µA - negligible standby power loss and signal integrity impact in always-on systems |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 24 V battery-fed ECUs exposed to load dump pulses up to 120 V and 400 ms duration. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to shunt surge current away from DC-DC converters and MCU power pins. Use Value: Clamps peak voltage to 118 V at 13 A, limiting stress on downstream 36 V-rated input stages while surviving >1000 surges per AEC-Q101. |
Use Scenario: 4–20 mA current loop transmitters interfacing with PLC analog inputs in factory automation. IC Role / Device Role / Timing Role: Bidirectional protection (via 1.5KE82CA variant) across signal lines to absorb EFT bursts and cable coupling noise. Use Value: Sub-5 ns response prevents latch-up in op-amps and ADC front-ends; <1 µA leakage avoids current-loop accuracy degradation. |
| Motor Drive IGBT Gate Protection | Lighting System Surge Suppression |
Use Scenario: High-side IGBT gate drivers in BLDC inverters subjected to Miller-induced voltage spikes during switching. IC Role / Device Role / Timing Role: Unidirectional 1.5KE82C placed between gate and emitter to clamp dv/dt-induced overshoot above 82 V threshold. Use Value: 1.0 ps response captures nanosecond-scale gate spikes before driver IC damage occurs; 1500 W rating handles repetitive switching transients. |
Use Scenario: LED driver modules in street lighting exposed to lightning-induced surges on AC mains input. IC Role / Device Role / Timing Role: Primary-stage TVS on bridge rectifier output to limit transient voltage before bulk capacitor and controller IC. Use Value: 118 V clamping voltage ensures <10% overvoltage margin for 100 V-rated electrolytic capacitors; DO-201 allows through-hole mounting on high-current traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ82A | Same DO-214AC (SMA) package; lower 400 W rating; 116 V clamping at 5.2 A | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial use | Select when space-constrained PCB layout favors surface-mount and automotive qualification is not required |
| Vishay 1.5SMC82C | DO-214AB (SMC) package; identical 1500 W rating; 118 V clamping at 13 A; same VBR range | Also AEC-Q101 qualified; slightly larger footprint than DO-201 but higher thermal mass | Prefer when board-level thermal management requires enhanced power dissipation or existing SMC footprint reuse is prioritized |
Compared with 1.5KE82C, SMAJ82A offers smaller size but sacrifices automotive qualification and surge capacity, while 1.5SMC82C matches performance and qualification at the cost of larger board area-making 1.5KE82C optimal for cost-sensitive, through-hole automotive modules needing proven DO-201 reliability.

FAQ
What is the key difference between 1.5KE82C and 1.5KE82CA?
The 1.5KE82C is unidirectional-designed for DC power rail protection where polarity is fixed and only reverse transients must be suppressed. The 1.5KE82CA is bidirectional, enabling symmetrical clamping for AC-coupled or floating signal lines like CAN bus or audio interfaces. Both share identical breakdown (73.8–90.2 V), clamping (118 V), and 1500 W surge ratings, but 1.5KE82CA has no cathode band and conducts in both directions.
Does 1.5KE82C meet AEC-Q101 requirements?
Yes, the 1.5KE82C is explicitly AEC-Q101 qualified per the manufacturer's documentation. This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress testing (UHAST), and mechanical shock-validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of 1.5KE82C under surge conditions?
The maximum clamping voltage of 1.5KE82C is 118 V, measured at 13 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage imposed on the protected circuit during worst-case transient events.
Can 1.5KE82C be used in place of a Zener diode for overvoltage protection?
No-1.5KE82C is not a replacement for a Zener diode in regulation applications. It is a transient suppressor optimized for high-energy, short-duration surges, not steady-state voltage regulation. Its leakage is specified only at VWM, and it lacks the tight tolerance and low dynamic impedance needed for precision biasing or reference functions. Use only for surge immunity, not DC voltage control.
What is the lead finish and solderability specification for 1.5KE82C?
The 1.5KE82C features pure tin-plated leads compliant with J-STD-002 for solderability, and passes JEDEC JESD201 Class 2 whisker testing. The molding compound meets UL 94V-0 flammability rating, and the device is RoHS-compliant and halogen-free per IEC 61249-2-21-ensuring reliable through-hole reflow and wave soldering in high-volume manufacturing.
