Product details

Overview

1.5KE8.2CA R0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 8.2V, working stand-off voltage 6.63V, clamping voltage 12.5V at 200A peak pulse current, and fast response time <5.0ns. It protects automotive power-line and industrial control interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.

For engineers reviewing the 1.5KE8.2CA R0G datasheet, 1.5KE8.2CA R0G pinout, 1.5KE8.2CA R0G application, or 1.5KE8.2CA R0G equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, DO-201 mechanical data, AEC-Q101 qualification status, and real-world ESD/inductive-spike protection use cases.

Technical Context

This bidirectional TVS operates symmetrically in both polarities, delivering identical V_BR (7.38–9.02V), I_PP (200A), and V_C (12.5V) characteristics across forward and reverse directions. Its low dynamic impedance ensures stable clamping under fast-rising transients up to 10/1000μs waveform.

Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and ISO 7637-2 immunity standards without derating at ambient temperatures up to 125°C. Junction temperature range spans –55°C to +175°C, supporting under-hood and industrial power rail deployments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR @ I_T = 10mA	7.38–9.02V: Ensures reliable turn-on before system-level overvoltage damages downstream ICs
V_WM	6.63V: Maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1000μA
V_C @ I_PP = 200A	12.5V: Clamped voltage seen by protected circuit during worst-case 10/1000μs surge-critical for 5V/3.3V logic survival
P_PK	1500W: Peak pulse power handling per single non-repetitive event, enabling robust protection against load dump and inductive kick
Response Time	<5.0ns (bidirectional): Guarantees suppression activation before transient energy couples into sensitive analog/digital inputs
Junction Temp Range	–55°C to +175°C: Supports operation in engine compartments, motor drives, and industrial PLC environments

Pinout & Package

Package: DO-201 axial-leaded plastic case with cathode band marking; RoHS-compliant, halogen-free molding compound (UL 94V-0); pure tin-plated leads solderable per J-STD-002; weight ≈ 0.090g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry point in forward bias	One terminal of symmetrical bidirectional structure-no fixed polarity; functions as cathode when reverse-biased
Cathode	Current exit point in forward bias	Marked band indicates terminal orientation; in bidirectional mode, either terminal serves as anode/cathode depending on transient polarity

Key Features

Feature	Design Value
Bidirectional clamping	Identical V_BR, V_C, and I_PP in both directions-eliminates need for polarity-aware board layout
AEC-Q101 qualification	Validated for automotive powertrain and body electronics-supports PPAP and long-term reliability requirements
ISO 7637-2 compliance	Withstands Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (ESD-related spikes)
Low dynamic impedance	Minimizes voltage overshoot during fast transients-critical for protecting 3.3V microcontrollers and CAN transceivers

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient voltage suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SMBJ8.0CA	Lower P_PK (600W), smaller SMB package, V_C = 12.6V @ 43.5A	Not suitable for 1500W ISO 7637-2 Pulse 1; limited to lower-energy ESD/inductive spikes	Select only for space-constrained consumer or telecom designs where peak surge energy is ≤600W
1.5SMC8.2CA	Same 1500W rating and DO-214AB package, V_C = 12.5V @ 200A, but not AEC-Q101 qualified	Lacks automotive qualification-requires additional validation for automotive OEM programs	Prefer when cost sensitivity outweighs AEC-Q101 requirement and DO-214AB footprint is acceptable

FAQ

What is the maximum clamping voltage of the 1.5KE8.2CA R0G during a 200A transient?

The 1.5KE8.2CA R0G exhibits a maximum clamping voltage (V_C) of 12.5V at 200A peak pulse current (I_PP) under the standard 10/1000μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage margining-ensuring compatibility with 5V logic families and automotive microcontrollers.

Is the 1.5KE8.2CA R0G qualified to AEC-Q101 standards?

Yes, the 1.5KE8.2CA R0G is AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "R0G" indicating automotive-grade screening. This qualification covers stress tests including HTGB, HTRB, TST, and mechanical shock-validating its suitability for automotive powertrain and body electronics applications.

How does the bidirectional design of the 1.5KE8.2CA R0G affect PCB layout?

The 1.5KE8.2CA R0G has no polarity-dependent function due to its symmetrical bidirectional construction-its marked cathode band is for mechanical orientation only. Engineers may place it in either direction across differential lines or unidirectional buses without altering protection behavior, simplifying layout and reducing BOM variants compared to unidirectional TVS diodes.

What is the working stand-off voltage (V_WM) of the 1.5KE8.2CA R0G, and why does it matter?

The 1.5KE8.2CA R0G has a working stand-off voltage (V_WM) of 6.63V, meaning it remains in high-impedance blocking state below this DC or RMS voltage while leaking less than 1000μA. This parameter ensures compatibility with 5V systems-allowing normal operation without false triggering while still responding rapidly to transients exceeding V_WM.

Does the 1.5KE8.2CA R0G meet ISO 7637-2 immunity requirements?

Yes, the 1.5KE8.2CA R0G is explicitly rated to meet ISO 7637-2 Pulse 1 (inductive load disconnect), Pulse 2a/2b (supply line transients), and Pulse 3a/3b (capacitive coupled fast transients). Taiwan Semiconductor confirms this compliance in the device's datasheet, making it suitable for direct integration into automotive 12V power distribution networks.
