Product details
Overview
1.5KE7.5A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 7.5V, minimum VBR 7.13V at 10mA, maximum clamping voltage 139V at 500A peak pulse current, and working stand-off voltage 6.40V - designed for automotive and industrial power rail protection against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE7.5A B0G datasheet, 1.5KE7.5A B0G pinout, 1.5KE7.5A B0G application, or 1.5KE7.5A B0G equivalent, this page delivers verified electrical parameters, DO-201 terminal polarity mapping, clamping performance under 10/1000μs surge, AEC-Q101 qualification status, and direct alternatives with documented VBR, IPP, and VC differences.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped overvoltage shunt device, triggered when reverse voltage exceeds its 7.13–7.88V breakdown range at 10mA test current. It delivers 1500W peak pulse power handling per 10/1000μs waveform with <1.0ps response time from 0V to VBR.
It features low dynamic impedance and <1μA leakage at 6.40V (VWM), enabling reliable hold-off during normal operation while clamping fast transients to ≤139V. Its DO-201 package supports lead-free soldering per J-STD-002 and meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=10mA | 7.13–7.88V: Ensures precise turn-on threshold for 7.5V nominal rail protection |
| VWM | 6.40V: Maximum continuous reverse voltage before leakage exceeds 1μA |
| VC @ IPP=500A | 139V: Clamped voltage during worst-case 10/1000μs surge - defines protected circuit's max stress |

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load dump and alternator switching transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and regulator input to clamp surges before LDO or DC/DC stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ7.5A | VBR = 7.22–8.02V; VC = 12.9V @ 48.8A; PPK = 400W; SMA package | Lower power rating and smaller package - suitable for board space-constrained, lower-energy circuits | Select when peak surge energy is ≤400W and DO-201 footprint is unavailable |
| ON Semiconductor 1.5SMC7.5A | VBR = 7.13–7.88V; VC = 13.4V @ 112A; PPK = 1500W; SMC package | Same clamping voltage range and power rating, but surface-mount SMC-2 package instead of axial DO-201 | Select for automated SMT assembly where through-hole DO-201 is incompatible with production flow |
Compared with 1.5KE7.5A B0G, SMAJ7.5A offers reduced surge capacity in a smaller package, while 1.5SMC7.5A matches its 1500W rating but requires PCB redesign for SMC footprint - neither is pin-compatible due to differing package types and terminal configurations.

FAQ
What is the breakdown voltage tolerance of the 1.5KE7.5A B0G?
The 1.5KE7.5A B0G has a guaranteed breakdown voltage range of 7.13V to 7.88V at 10mA test current, corresponding to ±5% tolerance around its nominal 7.5V rating. This tight VBR window ensures consistent clamping behavior across production lots and enables predictable system-level overvoltage margining in designs using the 1.5KE7.5A B0G.
Is the 1.5KE7.5A B0G AEC-Q101 qualified?
Yes, the 1.5KE7.5A B0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's documentation for the 1.5KE series with "H" or "A0G" suffix variants. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock, validating its suitability for automotive powertrain and body electronics applications where the 1.5KE7.5A B0G is deployed.
What is the maximum clamping voltage of the 1.5KE7.5A B0G under surge conditions?
The maximum clamping voltage (VC) of the 1.5KE7.5A B0G is 139V at 500A peak pulse current under the standard 10/1000μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is measured per ANSI/IEEE C62.35 - a critical parameter for verifying safe operation of downstream components in systems using the 1.5KE7.5A B0G.
Does the 1.5KE7.5A B0G have bidirectional capability?
No, the 1.5KE7.5A B0G is a unidirectional TVS diode, indicated by its "A" suffix and absence of bidirectional electrical specifications in its datasheet. It conducts only in reverse bias above VBR; forward conduction follows standard silicon diode behavior with ~3.5V drop at 50A. For bidirectional protection, Taiwan Semiconductor offers the 1.5KE7.5CA variant - the 1.5KE7.5A B0G must be oriented with cathode toward the protected line.
What package type does the 1.5KE7.5A B0G use, and what are its key mechanical properties?
The 1.5KE7.5A B0G uses the DO-201 axial-leaded package, featuring pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated molding compound, and polarity marked by a cathode band. Its weight is approximately 0.090g, and it passes JESD 201 Class 2 whisker testing - all mechanical attributes confirmed in Taiwan Semiconductor's official 1.5KE series datasheet for the 1.5KE7.5A B0G.
