Product details
Overview
1.5KE75CA B0G from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 75V, working stand-off voltage 60.7V, clamping voltage 108V at 14A peak pulse current, and fast response time <5.0ns. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE75CA B0G datasheet, 1.5KE75CA B0G pinout, 1.5KE75CA B0G application, or 1.5KE75CA B0G equivalent, key selection criteria include bidirectional clamping capability, 108V VC@IPP, AEC-Q101 qualification status, DO-201 mechanical compatibility, 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 1500W peak pulse power rating at 10/1000μs waveform and 108V maximum clamping voltage at 14A IPP ensure robust protection for 12V/24V automotive supply lines.
The device features low dynamic impedance and typical reverse leakage <1μA above 10V, enabling minimal standby power loss. Its junction temperature range of −55°C to +175°C supports under-hood deployment, and it meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DO-201 package: axial-leaded, cylindrical epoxy-molded case with cathode band marking for unidirectional variants; for bidirectional 1.5KE75CA B0G, polarity is non-directional - both terminals function identically as symmetrical avalanche junctions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | No functional distinction - either lead connects to protected line or ground; identical clamping in both directions |
Key Features

Applications
| Automotive Power Rail Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Suppressing load-dump transients on 12V/24V vehicle battery lines after alternator disconnection. IC Role / Device Role / Timing Role: Bidirectional TVS placed between power rail and chassis ground to clamp surges up to ±100V within nanoseconds. Use Value: Prevents damage to MCU power supplies and CAN transceivers by limiting rail voltage to ≤108V during ISO 7637-2 Pulse 2b events. | Use Scenario: Protecting digital input modules in programmable logic controllers from field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt fast transients before reaching optocoupler or level-shifter inputs. Use Value: Maintains signal integrity by clamping 8kV contact ESD (IEC 61000-4-2) to <110V, preserving input threshold margins. |
| LED Driver Surge Suppression | DC Motor Control Board Protection |
Use Scenario: Safeguarding constant-current LED drivers in streetlight systems exposed to lightning-induced surges on long feeder lines. IC Role / Device Role / Timing Role: Bidirectional TVS connected across driver output terminals to absorb differential-mode transients. Use Value: Limits voltage excursion to 108V during 1500W 10/1000μs surges, preventing MOSFET gate oxide rupture and current-sense amplifier saturation. | Use Scenario: Shielding H-bridge gate drivers and current-sense amplifiers from back-EMF spikes generated by brushed DC motors. IC Role / Device Role / Timing Role: TVS placed across motor terminals and/or power supply rails to clamp inductive switching spikes. Use Value: Reduces risk of latch-up in gate drivers by clamping 100V+ spikes to ≤108V within 5ns, ensuring uninterrupted PWM control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | DO-214AA (SMB) package, 75V VBR, 1000W PPK, 120V VC@IPP (12.3A) | Lower surge rating and higher clamping voltage; suited for space-constrained PCBs where 1500W margin is not required | Select SMBJ75CA when board area is limited and peak transient energy is ≤1000W |
| 1.5SMC75CA | DO-214AB (SMC) package, 75V VBR, 1500W PPK, 115V VC@IPP (13.0A) | Same power rating but 7V higher clamping voltage; slightly larger footprint than DO-201 | Choose 1.5SMC75CA if DO-201 lead spacing conflicts with existing layout but 1500W rating is mandatory |
Compared with 1.5KE75CA B0G, SMBJ75CA offers smaller size but reduced surge margin and higher clamping, while 1.5SMC75CA matches power rating but increases clamping voltage and requires larger PCB real estate - making 1.5KE75CA B0G optimal for cost-sensitive, high-reliability automotive power rail designs needing lowest VC and proven DO-201 manufacturability.

FAQ
What does the 'CA' suffix indicate in 1.5KE75CA B0G?
The 'CA' suffix in 1.5KE75CA B0G denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional 'A' variants, 1.5KE75CA B0G has no anode/cathode distinction and clamps equally for positive and negative voltage excursions, making it ideal for AC lines or floating DC buses where polarity is undefined.
Is 1.5KE75CA B0G AEC-Q101 qualified?
Yes, 1.5KE75CA B0G is AEC-Q101 qualified. The 'B0G' suffix indicates RoHS-compliant, green molding compound packaging, and the base 1.5KE75CA part is explicitly listed in Taiwan Semiconductor's AEC-Q101 qualified product documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), confirming suitability for automotive under-hood use.
What is the maximum clamping voltage of 1.5KE75CA B0G and at what current is it specified?
The maximum clamping voltage (VC) of 1.5KE75CA B0G is 108V, measured at a peak pulse current (IPP) of 14A under the standard 10/1000μs double-exponential waveform. This value represents the highest voltage the protected circuit will experience during a full-rated 1500W transient event, directly informing system-level overvoltage margin calculations for downstream ICs.
How does the DO-201 package of 1.5KE75CA B0G affect thermal performance?
With its DO-201 package, 1.5KE75CA B0G achieves a steady-state power dissipation of 5W when mounted on a 0.6" × 0.6" copper pad at TL = 75°C. The axial-leaded construction allows for through-hole mounting with optional heat sinking via lead bending or copper pour, supporting reliable operation at junction temperatures up to +175°C - critical for sustained surge duty cycles in automotive engine control units.
Does 1.5KE75CA B0G meet ISO 7637-2 immunity requirements?
Yes, 1.5KE75CA B0G is explicitly rated to meet ISO 7637-2 for Pulses 1 (inductive load dump), 2a (battery feed interruption), 2b (load dump with alternator), and 3a/3b (capacitive coupling and switching transients). Its 108V clamping voltage at 14A IPP ensures compliance with the voltage limits defined in these test pulses for 12V systems, providing validated protection for automotive ECUs and body control modules.
