Product details
Overview
1.5KE82CA B0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 82V, working stand-off voltage 66.4V, clamping voltage 118V at 13A peak pulse current, and AEC-Q101 qualification for automotive use. It protects power rails and signal lines against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients in vehicle ECUs.
For engineers reviewing the 1.5KE82CA B0G datasheet, 1.5KE82CA B0G pinout, 1.5KE82CA B0G application, or 1.5KE82CA B0G equivalent, key selection criteria include bidirectional clamping performance, 10/1000μs surge rating, junction temperature range (−55°C to +175°C), and compliance with automotive ESD and EFT immunity standards.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, delivering consistent clamping behavior across positive and negative transients. Its low dynamic impedance and sub-nanosecond response time (<1ps for unidirectional, 5ns for bidirectional) ensure rapid suppression of fast-rising ESD and EFT events.
The device meets ISO 7637-2 test requirements for automotive load-dump and switching transients, with a maximum clamping voltage of 118V at 13A IPP and leakage current <1μA at 66.4V VWM. Junction temperature capability up to +175°C supports under-hood deployment without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8V / 90.2V @ IT = 1mA - defines reliable conduction onset across process variation |
| VWM | 66.4V - maximum continuous DC or RMS voltage before significant leakage |
| VC @ IPP | 118V @ 13A - peak clamped voltage during 10/1000μs surge, limiting downstream stress |
| PPK | 1500W - non-repetitive surge power handling per JEDEC standard waveform |
| Junction Temp Range | −55°C to +175°C - enables operation in engine bay and industrial control environments |
| Leakage @ VWM | <1μA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Temp Coefficient | 0.105%/°C - predictable VBR drift over temperature for stable protection threshold |
Pinout & Package
DO-201 axial package with cathode band marking; two-terminal bidirectional configuration - no polarity sensitivity in circuit placement. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals serve as interchangeable surge current entry/exit points; no directional bias required |
| Case (non-connected) | Mechanical mounting only | DO-201 body provides thermal mass but no electrical connection; no heatsink pad required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in differential or AC-coupled lines |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - suitable for ECU, ADAS, and body control modules |
| ISO 7637-2 compliance | Passes Pulse 1 (inductive load dump), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (EFT) - reduces need for additional filtering stages |
| Low clamping ratio | VC/VBR ≈ 1.57 - tight voltage margin between standoff and clamp ensures robust IC-level protection without overdesign |
| Halogen-free & RoHS | Meets IEC 61249-2-21 and EU RoHS directives - supports green manufacturing and end-of-life compliance |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | 600W rating, SMB package (smaller footprint), VC = 137V @ 4.4A | Lower surge capacity; suited for space-constrained consumer electronics, not automotive load-dump | Select when board area is critical and peak surge energy is ≤600W |
| 1.5SMC82CA | Same 1500W rating and VBR, but SMC package (surface-mount), VC = 118V @ 13A | Compatible clamping performance; requires rework for through-hole vs. SMT assembly | Choose for automated SMT production where DO-201 axial insertion is impractical |
Compared with SMBJ85CA and 1.5SMC82CA, the 1.5KE82CA B0G offers proven axial-mount ruggedness for high-energy automotive transients, AEC-Q101 validation, and identical clamping voltage - making it the preferred choice for under-hood power rail protection where mechanical reliability and surge margin are paramount.

FAQ
What does the 'CA' suffix indicate in 1.5KE82CA B0G?
The 'CA' suffix in 1.5KE82CA B0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. This is essential for protecting AC-coupled signals, differential buses like CAN, and ungrounded power domains where polarity reversal can occur during transients.
Is 1.5KE82CA B0G suitable for ISO 7637-2 Pulse 1 testing?
Yes, 1.5KE82CA B0G is explicitly rated to meet ISO 7637-2 Pulse 1 (inductive load dump) requirements. With its 1500W peak pulse power rating and 118V clamping voltage at 13A, it limits induced voltages to safe levels for downstream 12V-rated components during simulated alternator disconnection events.
What is the maximum operating temperature for 1.5KE82CA B0G?
The 1.5KE82CA B0G has a maximum junction temperature (TJ) of +175°C and storage temperature range of −55°C to +175°C. This wide thermal envelope allows direct placement near heat sources in automotive engine compartments and industrial motor drives without thermal derating below full 1500W surge capability.
How does the DO-201 package of 1.5KE82CA B0G affect PCB layout?
The DO-201 axial package of 1.5KE82CA B0G requires through-hole mounting with 0.2" (5.08mm) lead spacing. Its mechanical robustness supports high-vibration environments, but layout must accommodate axial orientation and sufficient clearance for 1.5kW surge dissipation - typically using copper pour thermal relief and avoiding narrow traces in the transient current path.
Does 1.5KE82CA B0G require a heatsink for 1500W surge handling?
No, 1.5KE82CA B0G handles its rated 1500W surge without an external heatsink, as the energy is dissipated in a single 10/1000μs pulse. The DO-201 package's thermal mass and lead-frame design provide adequate transient thermal capacity; however, steady-state power dissipation is limited to 5W at TL = 75°C, so continuous operation requires appropriate ambient management.
