Product details
Overview
1.5KE100A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 100V nominal breakdown voltage (VBR min/max = 95V/105V), 85.5V working stand-off voltage (VWM), and 137V clamping voltage (VC) at 11.4A peak impulse current. It protects automotive power rails and industrial I/O interfaces against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE100A B0G datasheet, 1.5KE100A B0G pinout, 1.5KE100A B0G application, or 1.5KE100A B0G equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA @ 85.5V), AEC-Q101 qualification status, thermal derating above 25°C, and DO-201 mechanical compatibility with standard PCB footprints.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (95–105V), it avalanches to divert surge current away from downstream circuitry. Its 137V clamping voltage at 11.4A ensures protected ICs experience <137V during worst-case 1500W surges.
Designed for automotive-grade reliability, it meets ISO 7637-2 immunity requirements and supports operation from –55°C to +175°C junction temperature. The DO-201 package enables high-power dissipation (1500W peak, 5W steady-state at TL = 75°C) with pure tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 95–105V: precise avalanche initiation range ensuring consistent turn-on across temperature and unit variation |
| VWM | 85.5V: maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP = 11.4A | 137V: clamped voltage during full 1500W 10/1000μs surge-critical for downstream IC voltage margining |
| ID @ VWM | <1μA: ultra-low leakage preserves system standby power and avoids false triggering |
| PPK | 1500W: peak pulse power rating per JEDEC standard 10/1000μs waveform |
| TJ max | +175°C: extended junction temperature rating enables under-hood automotive deployment |
| Package | DO-201: industry-standard axial leaded package with UL 94V-0 molding compound and JESD 201 Class 2 whisker resistance |
Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; defines polarity for unidirectional clamping |
| Cathode | Protected line input | Connected to line being protected (e.g., 12V rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 1500W surge capability | Withstands automotive load-dump and inductive switching transients without degradation |
| Clamping voltage ≤137V @ 11.4A | Guarantees downstream 150V-rated components remain within safe operating area during full-rated surge |
| Leakage <1μA @ 85.5V | Minimizes quiescent current draw in always-on automotive modules (e.g., CAN nodes, body controllers) |
| AEC-Q101 qualified option available | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive flyback), Pulse 2a/2b (battery disconnect), and Pulse 3a/3b (switching noise) immunity standards |
Applications
| Automotive Power Rail Protection | Industrial I/O Interface Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between power rail and chassis ground to clamp overvoltage before it reaches LDOs and microcontrollers. Use Value: Limits rail voltage to ≤137V during 1500W surges, preserving 150V input-rated regulators and preventing latch-up in 3.3V/5V logic. | Use Scenario: RS-485/RS-232 ports on PLCs subjected to EFT bursts and cable-induced surges. IC Role / Device Role / Timing Role: Line-side TVS on signal lines referenced to local ground, absorbing fast transients before they couple into transceivers. Use Value: Sub-nanosecond response time ensures clamping initiates before EFT edge (5ns rise) propagates into IC inputs, reducing bit errors. |
| LED Driver Output Protection | DC-DC Converter Input Protection |
Use Scenario: Constant-current LED drivers powering exterior lighting where inductive kickback from relay coils induces voltage spikes. IC Role / Device Role / Timing Role: TVS placed across driver output terminals to absorb reverse EMF from solenoid/relay loads. Use Value: 137V clamping prevents damage to MOSFET output stages rated for 150V drain-source breakdown. | Use Scenario: Buck converter input fed from unregulated 24V industrial supply subject to switching noise and hot-swap events. IC Role / Device Role / Timing Role: Primary-side TVS on VIN pin to limit input voltage excursions before front-end EMI filter and controller IC. Use Value: 85.5V VWM allows stable operation across full 24V ±20% input range while clamping surges to safe levels for 36V-rated input capacitors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ100A | Same DO-214AC (SMA) package; 100V VBR (95–105V), 137V VC @ 11.2A, but lower PPK = 400W | Not suitable for 1500W load dump; limited to lower-energy ESD/EFT scenarios | Select only when surge energy is ≤400W and space-constrained SMT layout is required |
| ON Semiconductor 1.5SMC100A | DO-214AB (SMC) package; identical 100V VBR (95–105V), 137V VC @ 11.4A, PPK = 1500W, but no AEC-Q101 variant offered | Lacks automotive qualification documentation; requires customer qualification for automotive use | Acceptable for industrial applications where AEC-Q101 is not mandated |

FAQ
What is the clamping voltage of the 1.5KE100A B0G under a 10/1000μs surge?
The 1.5KE100A B0G has a maximum clamping voltage (VC) of 137V when subjected to a 10/1000μs surge waveform at its rated peak impulse current of 11.4A. This value is measured per JEDEC standards and guarantees that downstream circuitry sees no more than 137V during full 1500W transient events. The 1.5KE100A B0G maintains this clamping performance across its specified junction temperature range of –55°C to +175°C.
Is the 1.5KE100A B0G AEC-Q101 qualified?
The 1.5KE100A B0G itself is not marked as AEC-Q101 qualified; however, the 1.5KE100AH variant (with "H" suffix) is explicitly AEC-Q101 qualified per the manufacturer's ordering information. The 1.5KE100A B0G shares identical electrical and thermal specifications but lacks the formal automotive qualification testing documentation. For automotive applications requiring certified qualification, specify 1.5KE100AH instead of 1.5KE100A B0G.
What is the working stand-off voltage (VWM) of the 1.5KE100A B0G?
The working stand-off voltage (VWM) of the 1.5KE100A B0G is 85.5V. This is the maximum continuous DC or RMS voltage the device can withstand in reverse bias without exceeding the specified leakage current of 1μA. It ensures reliable operation on 72–96V industrial systems or 12V/24V automotive rails with wide tolerance margins, while maintaining low standby leakage critical for always-on modules.
How does the 1.5KE100A B0G differ from the 1.5KE100 version?
The 1.5KE100A B0G is the "A" grade version of the 1.5KE100 series, featuring tighter VBR tolerance: 95–105V versus 90–110V for the standard 1.5KE100. This improved breakdown voltage consistency reduces design margin uncertainty and improves predictability in clamping behavior. Both share identical DO-201 packaging, 1500W PPK rating, and thermal specifications-but only the "A" grade guarantees the narrower VBR window essential for precision rail protection.
What is the maximum junction temperature rating for the 1.5KE100A B0G?
The maximum junction temperature (TJ max) for the 1.5KE100A B0G is +175°C. This rating enables reliable operation in high-temperature environments such as engine compartments, industrial motor drives, and enclosed LED fixtures. The device's thermal performance is validated up to this limit, and derating curves (per Fig.2 in the datasheet) define allowable peak power reduction above 25°C ambient-ensuring safe 1500W surge handling even at elevated board temperatures.
