Product details
Overview
1.5KE8.2C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-201 package, designed for high-energy surge protection in automotive and industrial systems. It features a nominal breakdown voltage of 8.2 V, 1500 W peak pulse power rating at 10/1000 μs waveform, clamping voltage of 12.5 V at 200 A peak impulse current, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements.
For engineers reviewing the 1.5KE8.2C datasheet, 1.5KE8.2C pinout, 1.5KE8.2C application, or 1.5KE8.2C equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, DO-201 mechanical data, AEC-Q101 qualification status, and real-world ESD/inductive switching protection use cases - all confirmed from Taiwan Semiconductor's official O2104 specification document.
Technical Context
The 1.5KE8.2C operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal lines without polarity concerns. Its breakdown voltage range is 7.38–9.02 V at 10 mA test current, and it maintains low dynamic impedance to limit voltage overshoot during fast transients.
It delivers 1500 W surge capability per JEDEC standard 10/1000 μs waveform, with clamping voltage capped at 12.5 V under 200 A peak impulse current. Thermal performance supports junction temperatures from –55 °C to +175 °C, and its DO-201 package enables surface-mount-compatible through-hole mounting with pure tin-plated leads compliant with J-STD-002.
Key Specifications

Pinout & Package
1.5KE8.2C is a two-terminal bidirectional TVS diode in DO-201 package. No polarity marking is used; terminals are functionally identical and interchangeable. The device has no cathode band - consistent with bipolar construction for symmetrical transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Both terminals serve as interchangeable surge conduction paths; no DC polarity dependency |
| Lead 1 / Lead 2 | Current path interface | Through-hole solderable terminals with pure tin plating; compatible with wave and hand soldering per J-STD-002 |

| ISO 7637-2 compliance | Validated against Pulse 1 (inductive load disconnect), Pulse 2a/2b (battery interruption), and Pulse 3a/3b (switching noise) |
| AEC-Q101 qualified option | 1.5KE8.2CH variant available for automotive-grade reliability; standard 1.5KE8.2C is industrial-qualified |
| Low clamping ratio (VC/VBR ≈ 1.52) | Minimizes overvoltage margin between breakdown and clamping, improving system-level robustness |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting LIN bus transceivers and body control module inputs from battery load dump and alternator ripple. IC Role / Device Role: Bidirectional TVS placed across power rail and ground to clamp transients before they reach sensitive analog front-ends. Use Value: Limits voltage excursion to ≤12.5 V during 200 A surges, preventing latch-up or permanent damage to 5 V/3.3 V ICs. |
Use Scenario: Safeguarding 4–20 mA current loop transmitters against ESD and field wiring faults in factory automation. IC Role / Device Role: Placed differentially across loop terminals to absorb ±8 kV contact ESD (IEC 61000-4-2) and inductive kickback. Use Value: Symmetrical clamping ensures equal protection regardless of fault polarity, eliminating need for dual unidirectional devices. |
| LED Driver Input Stage | RS-485 Transceiver Port |
|

Use Value: Clamps to 12.5 V within <5 ns, preventing receiver saturation and maintaining data validity during transient events. |
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 SMAJ8.0CA | DO-214AC (SMA) package; 8.0 V nominal VBR; 400 W rating; lower IPP (45.5 A) | Lower power handling limits suitability to sub-100 V surges; better suited for PCB space-constrained consumer designs | Select when board area is critical and surge energy is ≤400 W; not drop-in due to package and power mismatch |
| ON Semiconductor 1.5SMC8.2CA | DO-214AB (SMC) package; same 8.2 V nominal VBR; 1500 W rating; identical VC (12.5 V) | Same clamping performance but larger SMC footprint; higher thermal mass improves repetitive surge endurance | Choose for enhanced thermal cycling reliability in high-duty-cycle industrial environments; requires PCB layout change |
Compared with 1.5KE8.2C, SMAJ8.0CA trades surge capacity for compactness, while 1.5SMC8.2CA matches power rating but demands more board area and offers superior thermal resilience - making 1.5KE8.2C optimal for cost-sensitive, medium-energy automotive and industrial point-of-load protection where DO-201 is already standardized.

FAQ
What does the 'C' suffix mean in 1.5KE8.2C?
The 'C' suffix in 1.5KE8.2C denotes bidirectional configuration - meaning the device provides symmetrical clamping in both polarities, with identical breakdown and clamping characteristics across either terminal pair. This distinguishes it from unidirectional variants like 1.5KE8.2, which include a cathode band and conduct only in reverse bias. The 1.5KE8.2C has no polarity marking and is used where AC or floating signal protection is required.
Is 1.5KE8.2C AEC-Q101 qualified?
The base 1.5KE8.2C part is not AEC-Q101 qualified; however, Taiwan Semiconductor offers the 1.5KE8.2CH variant (with 'H' suffix) that is fully AEC-Q101 qualified for automotive applications. The 'H' version undergoes additional stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification per AEC standards - while maintaining identical electrical specs and DO-201 packaging as the 1.5KE8.2C.
What is the maximum clamping voltage of 1.5KE8.2C under surge conditions?
The maximum clamping voltage (VC) of 1.5KE8.2C is 12.5 V, measured at a peak impulse current (IPP) of 200 A using the standard 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage the device allows to appear across protected circuitry during worst-case transient events.
Can 1.5KE8.2C replace 1.5KE8.2 in an existing design?
No - 1.5KE8.2C and 1.5KE8.2 are not interchangeable without circuit review. The 1.5KE8.2 is unidirectional (cathode-banded) and conducts only in reverse bias, while the 1.5KE8.2C is bidirectional with no polarity. Substituting one for the other may cause unintended conduction or failed protection depending on placement. Always verify schematic polarity and protection topology before replacement.
What is the leakage current specification for 1.5KE8.2C at its working voltage?
At its maximum working stand-off voltage (VWM) of 6.63 V, the 1.5KE8.2C exhibits a maximum blocking leakage current (ID) of 1 µA at 25 °C. This low leakage ensures minimal power loss and signal interference in always-on circuits such as automotive wake-up lines or sensor bias networks - a key advantage over higher-leakage alternatives in battery-powered systems.
