Product details
Overview
1.5KE8.2CA B0G 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 junction temperature range −55°C to +175°C. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE8.2CA B0G datasheet, 1.5KE8.2CA B0G pinout, 1.5KE8.2CA B0G application, or 1.5KE8.2CA B0G equivalent, key selection criteria include bidirectional clamping capability, 12.5V VC@200A, DO-201 mechanical compatibility, AEC-Q101 qualification status, and compliance with ISO 7637-2 immunity requirements.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance regardless of transient polarity. Its low dynamic impedance and sub-nanosecond response time (<5.0ns from 0V to VBR) enable effective suppression of fast electrical fast transients (EFT) and inductive switching spikes.
The device meets ISO 7637-2 test pulses 1, 2a, 2b, 3a, and 3b without derating at ambient temperatures up to 75°C when mounted on a 16mm × 16mm copper pad. Its 1500W peak pulse power rating at 10/1000μs waveform and 12.5V clamping voltage at 200A IPP ensure robust protection for 12V automotive electronics and industrial control inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR Min/Max | 7.38V / 9.02V at 10mA test current - defines reliable conduction onset window for bidirectional clamping |
| VWM | 6.63V - maximum continuous reverse voltage before leakage exceeds 1000μA, sets safe operating margin below VBR |
| VC@IPP | 12.5V at 200A peak pulse - limits protected circuit voltage during worst-case 10/1000μs surge |
| PPK | 1500W - peak pulse power handling per JEDEC standard, supports high-energy automotive load dump events |
| IPP | 200A - maximum non-repetitive peak impulse current, determines minimum series impedance required for full protection |
| TJ Range | −55°C to +175°C - enables deployment in under-hood automotive and industrial environments without thermal derating |
| Package | DO-201 - industry-standard axial leaded package with 0.090g mass, UL 94V-0 molding compound, and tin-plated leads |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional variants; for bidirectional 1.5KE8.2CA B0G, polarity is symmetrical and cathode band is not functional - terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient conduction path | Either terminal serves as input/output - no polarity sensitivity; connects across protected line and ground or between differential lines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPP in both directions - eliminates need for polarity-aware layout in DC bus or signal line protection |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for ASIL-B system interfaces |
| ISO 7637-2 compliance | Passes Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) - reduces validation effort for automotive ECUs |
| Low clamping ratio | VC/VBR = 12.5/7.38 ≈ 1.7 - minimizes overvoltage stress on downstream ICs compared to higher-ratio suppressors |
| Fast response time | <5.0ns rise-to-clamp - captures sub-microsecond transients before sensitive logic or analog circuits are damaged |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | DO-214AA package, 600W PPK, VC = 13.6V @ 17.3A - lower power rating and higher clamping voltage | Surface-mount only; unsuitable for through-hole PCBs or high-energy load dump events | Select when board space is constrained and peak surge energy is ≤600W |
| 1.5SMC8.2CA | DO-214AB package, 1500W PPK, VC = 12.6V @ 192A - same clamping performance but SMC footprint | Requires rework of mounting pads and thermal relief; incompatible with DO-201 socket or axial lead routing | Select when migrating to surface-mount assembly and thermal management allows SMC footprint |
Compared with SMBJ8.0CA and 1.5SMC8.2CA, the 1.5KE8.2CA B0G provides proven axial-lead mechanical robustness for high-vibration environments, maintains lowest clamping voltage among 1500W DO-201 options, and delivers AEC-Q101 qualification without requiring redesign of existing through-hole layouts.

FAQ
What does the "CA" suffix indicate in 1.5KE8.2CA B0G?
The "CA" suffix in 1.5KE8.2CA B0G denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions. This distinguishes it from unidirectional "A" variants like 1.5KE8.2A, and ensures protection against voltage transients of either polarity without requiring orientation-specific placement on the PCB. The 1.5KE8.2CA B0G is fully specified for bidirectional use per Taiwan Semiconductor's 1.5KE series documentation.
Is 1.5KE8.2CA B0G AEC-Q101 qualified?
Yes, 1.5KE8.2CA B0G is AEC-Q101 qualified. The "B0G" ordering code indicates green, halogen-free packaging and confirms qualification to the AEC-Q101 stress test standard for discrete semiconductors. This includes testing for high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge - making the 1.5KE8.2CA B0G suitable for automotive applications up to ASIL-B safety integrity level.
What is the clamping voltage of 1.5KE8.2CA B0G at its rated peak pulse current?
The clamping voltage (VC) of 1.5KE8.2CA B0G is 12.5V at 200A peak pulse current (IPP) under the standard 10/1000μs waveform. This value is measured across the device terminals during surge conduction and represents the maximum voltage imposed on the protected circuit during worst-case transient events. The 1.5KE8.2CA B0G maintains this clamping performance consistently in both directions due to its bidirectional design.
Can 1.5KE8.2CA B0G be used in place of a unidirectional TVS diode?
No - 1.5KE8.2CA B0G must not replace a unidirectional TVS diode in circuits where DC bias polarity is fixed and reverse conduction must be blocked. As a bidirectional device, the 1.5KE8.2CA B0G conducts in both directions once VBR is exceeded, which could cause unintended current paths or increased leakage in DC-coupled applications. Use only where symmetrical transient protection is required, such as AC lines, differential buses, or floating DC rails.
What is the maximum working stand-off voltage (VWM) for 1.5KE8.2CA B0G?
The maximum working stand-off voltage (VWM) for 1.5KE8.2CA B0G is 6.63V. This is the highest continuous DC or RMS voltage the device can withstand without exceeding 1000μA leakage current. It establishes the safe operating margin below the minimum breakdown voltage (7.38V), ensuring the 1.5KE8.2CA B0G remains non-conductive during normal operation while remaining responsive to transients exceeding VWM.
