Product details
Overview
1.5KE82A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 82V, minimum VBR = 77.9V at 1mA, maximum clamping voltage VC = 113V at 13.9A peak pulse current, and working stand-off voltage VWM = 70.1V - designed for automotive-grade ESD and load-dump protection in power supply rails and interface lines.
For engineers reviewing the 1.5KE82A B0G datasheet, 1.5KE82A B0G pinout, 1.5KE82A B0G application, or 1.5KE82A B0G equivalent, key selection criteria include its AEC-Q101 qualification, 10/1000μs surge rating, low dynamic impedance, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and unidirectional polarity marking for correct PCB orientation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 70.1V, then rapidly avalanches above VBR (77.9–86.1V) to limit transient energy. Its junction temperature range spans −55°C to +175°C, supporting under-hood automotive deployment.
Clamping performance is defined by VC = 113V at IPP = 13.9A (10/1000μs waveform), with typical leakage <1μA at rated VWM, and forward voltage VF = 3.5V at 50A - confirming suitability for DC power rail protection where low conduction loss matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 70.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1μA; sets safe margin below system rail. |
| VBR @ IT = 1mA | 77.9–86.1 V - Breakdown voltage range defining turn-on threshold; tight tolerance supports predictable clamping onset. |
| VC @ IPP = 13.9A | 113 V - Clamped voltage during 10/1000μs surge; determines maximum stress on downstream ICs. |
| PPK | 1500 W - Peak pulse power handling capability; enables robust protection against ISO 7637-2 load-dump transients. |
| Junction Temp. Range | −55°C to +175°C - Extended thermal envelope allowing placement near heat sources in automotive ECUs. |
| Package | DO-201 - Industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding, and 0.090g mass. |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional polarity. 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 | Low-side reference terminal | Connected to ground or low-potential node; defines current path during avalanche conduction. |
| Cathode | High-side input terminal | Marked with band; connects to protected line (e.g., 12V rail); carries full surge current into ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - enables use in engine control, ADAS, and body modules. |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (ESD coupling) - covers full vehicle-level EMC immunity. |
| 10/1000μs surge rating | 1500W peak power at standard lightning/surge waveform - matches OEM transient test profiles without derating. |
| Low dynamic impedance | Ensures rapid voltage clamping (<1ps response from 0V to VBR) - minimizes overshoot during fast ESD events. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS directives - supports green manufacturing and end-of-life recycling. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ82A | Same DO-214AC (SMA) package; VBR = 91.1–100.7V; VC = 137V @ 10.9A; 400W rating. | Lower power rating and higher clamping voltage - suitable for non-automotive, lower-energy surges. | Select when footprint constraints favor surface-mount or when 400W surge capacity suffices. |
| ON Semiconductor 1.5SMC82A | DO-214AB (SMC) package; VBR = 91.1–100.7V; VC = 137V @ 10.9A; 1500W rating; AEC-Q101 option available. | Same power rating but larger SMC footprint; identical clamping performance but different thermal mass. | Choose for board space flexibility or when existing SMC land pattern is standardized. |
Compared with 1.5KE82A B0G, SMAJ82A offers smaller size but reduced surge capability and higher clamping, while 1.5SMC82A matches power and AEC-Q101 support but requires larger PCB area - making 1.5KE82A B0G optimal for cost-sensitive, high-reliability axial-leaded designs.

FAQ
What is the exact breakdown voltage range for 1.5KE82A B0G?
The 1.5KE82A B0G has a guaranteed breakdown voltage range of 77.9V to 86.1V at test current IT = 1mA, per Taiwan Semiconductor's O2104 datasheet revision. This range reflects process variation and ensures reliable turn-on behavior across production lots while maintaining compatibility with 82V nominal system rails.
Is 1.5KE82A B0G AEC-Q101 qualified?
Yes, 1.5KE82A B0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's ordering code suffix "B0G", where "B" denotes AEC-Q101 compliance per the official ordering information table. This qualification covers temperature cycling, mechanical shock, humidity, and accelerated life testing required for automotive under-hood applications.
What does the "B0G" suffix mean in 1.5KE82A B0G?
The "B0G" suffix in 1.5KE82A B0G indicates AEC-Q101 qualification ("B"), green (halogen-free) compound ("G"), and standard packaging configuration. It is not a date code or factory identifier - this coding aligns with Taiwan Semiconductor's documented ordering convention in the 1.5KE series datasheet Version O2104.
Can 1.5KE82A B0G be used in bidirectional configurations?
No - 1.5KE82A B0G is strictly unidirectional, as indicated by its single cathode band marking and specification of VBR only in one polarity. For bidirectional protection, Taiwan Semiconductor specifies the "CA" suffix (e.g., 1.5KE82CA), which uses symmetrical breakdown characteristics in both directions.
What is the maximum clamping voltage of 1.5KE82A B0G under surge conditions?
The maximum clamping voltage of 1.5KE82A B0G is 113V at peak pulse current IPP = 13.9A with a 10/1000μs waveform, as specified in the Electrical Characteristics table. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
