Product details
Overview
1.5KE7.5AHR0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 7.5V, working stand-off voltage 6.40V, clamping voltage 139V at 500A peak pulse current, and junction temperature range −55°C to +175°C - designed for automotive-grade ESD and load-dump protection in power supply rails and sensor interfaces.
For engineers reviewing the 1.5KE7.5AHR0G datasheet, 1.5KE7.5AHR0G pinout, 1.5KE7.5AHR0G application, or 1.5KE7.5AHR0G equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, thermal derating behavior, and real-world clamping performance under 10/1000μs surge conditions.
Technical Context
The 1.5KE7.5AHR0G operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 7.13–7.88V breakdown range at 10mA test current. Its low dynamic impedance enables rapid clamping response (<1.0ps from 0V to VBR) and limits transient energy dissipation across sensitive downstream circuitry.
Rated for 1500W non-repetitive peak pulse power per 10/1000μs waveform, it sustains 5W steady-state power at 75°C lead temperature and withstands 200A forward surge current (8.3ms half-sine). Its −55°C to +175°C operating junction temperature supports under-hood automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 10mA | 7.13–7.88V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 6.40V - maximum continuous reverse operating voltage before leakage rises significantly |
| IPP @ 10/1000μs | 500A - peak surge current it safely shunts without failure, enabling robust 1500W transient handling |
| VC @ IPP | 139V - clamped voltage seen by protected circuit during full-rated surge, limiting stress on downstream ICs |
| ID @ VWM | <1μA - ultra-low blocking leakage ensures minimal standby power loss in battery-powered systems |
| TJ Range | −55°C to +175°C - validated operation across automotive under-hood and industrial ambient extremes |
| AEC-Q101 Qualified | Yes - certified for automotive electronic modules requiring high-reliability transient suppression |
Pinout & Package
Package: DO-201 axial-leaded plastic case with cathode band marking; RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads solderable per J-STD-002, and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential rail; conducts during positive transients in bidirectional configs (not applicable here) |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12V rail); conducts reverse current when VREV > VBR, diverting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated reliability for automotive ECUs, body control modules, and ADAS power domains |
| 1500W 10/1000μs surge rating | Withstands severe load-dump and ISO 7637-2 Pulse 5a events without degradation |
| Clamping voltage ≤139V at 500A | Ensures protected 5V/3.3V logic rails remain below absolute maximum ratings during surge |
| Leakage <1μA above 6.4V | Minimizes quiescent current draw in always-on vehicle networks (e.g., CAN standby) |
| Fast response <1.0ps | Engages before transient edge propagates into IC input stages, preventing latch-up or gate oxide damage |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12V battery rail in engine control unit exposed to ISO 7637-2 Pulse 5a (load dump up to 60V, 400ms). IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and DC-DC input, clamping surges before they reach regulator ICs. Use Value: Limits peak voltage to ≤139V, preserving input capacitor voltage rating and preventing regulator shutdown or destruction. |
Use Scenario: 24V analog sensor signal line (e.g., pressure transducer) routed near motor drives in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, shunting inductive kickback and EFT bursts to chassis ground. Use Value: Maintains signal integrity by suppressing transients within 1ps, avoiding ADC offset shifts or op-amp saturation. |
| LED Lighting Driver Input Protection | Telecom Power Supply Surge Suppression |
Use Scenario: Constant-current LED driver powered from 48V telecom rectifier subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-line TVS on input bulk capacitor node, absorbing 1500W pulses per ITU-T K.20/21. Use Value: Prevents MOSFET gate-oxide rupture and controller IC latch-up during repeated surge events. |
Use Scenario: -48V DC power input of base station radio unit exposed to induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Unidirectional TVS on supply rail upstream of DC-DC converters and PMICs. Use Value: Clamps to 139V while maintaining <1μA leakage, ensuring no impact on system efficiency or standby current budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower peak power (600W), smaller SMB package (vs. DO-201), VBR = 7.78–8.61V, VC = 12.4V @ 43.3A | Better suited for PCB space-constrained consumer electronics; insufficient for automotive load-dump duty | Select only for cost-sensitive, non-automotive 12V rail protection where surge energy ≤600W |
| 1.5SMC7.0A | Same 1500W rating but SMC package (surface-mount), VBR = 7.22–7.98V, VC = 12.4V @ 121A | Enables automated assembly and higher board density; lacks AEC-Q101 certification out-of-box | Choose when reflow compatibility and layout miniaturization outweigh automotive qualification requirements |
Compared with 1.5KE7.5AHR0G, SMBJ7.0A trades surge robustness for footprint reduction, while 1.5SMC7.0A matches power rating but requires separate AEC-Q101 validation for automotive use - making 1.5KE7.5AHR0G the only drop-in qualified solution for production automotive power rails.

FAQ
What does the 'H' suffix in 1.5KE7.5AHR0G indicate?
The 'H' in 1.5KE7.5AHR0G denotes AEC-Q101 qualification - confirming that the 1.5KE7.5AHR0G has passed accelerated stress testing for automotive-grade reliability, including temperature cycling, humidity bias, and high-temperature operating life. This makes the 1.5KE7.5AHR0G suitable for safety-critical vehicle subsystems where standard commercial TVS diodes would not be approved.
How does the clamping voltage of 1.5KE7.5AHR0G compare to its breakdown voltage?
The 1.5KE7.5AHR0G has a breakdown voltage (VBR) range of 7.13–7.88V at 10mA, but clamps transients to ≤139V at its rated 500A peak pulse current. This 17× voltage margin reflects the device's ability to absorb massive surge energy while limiting stress on downstream components - a critical distinction from Zener diodes, which lack controlled high-current clamping capability.
Is 1.5KE7.5AHR0G suitable for bidirectional transient protection?
No - the 1.5KE7.5AHR0G is a unidirectional TVS diode, intended for DC circuits with defined polarity (e.g., +12V rail to ground). For bidirectional AC or floating-line protection, a bipolar variant such as 1.5KE7.5CA or 1.5KE7.5CAHR0G must be used, as the 1.5KE7.5AHR0G will conduct heavily in forward bias and cannot suppress positive transients on grounded lines.
What is the maximum allowable mounting temperature for 1.5KE7.5AHR0G during reflow soldering?
The 1.5KE7.5AHR0G uses a DO-201 package with pure tin-plated leads compliant with J-STD-002, supporting standard SnPb and lead-free reflow profiles. Peak reflow temperature must not exceed 260°C for ≤10 seconds, and preheat ramp rate should stay within 3°C/s to avoid internal delamination - consistent with IPC-J-STD-020 guidelines for plastic-encapsulated discrete devices.
Does 1.5KE7.5AHR0G meet ISO 7637-2 Pulse 5a requirements?
Yes - the 1.5KE7.5AHR0G is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b, and its 1500W 10/1000μs surge capability covers the energy profile of Pulse 5a (load dump) when applied with appropriate series impedance. System-level validation is still required, but the 1.5KE7.5AHR0G provides the foundational clamping performance needed to pass Pulse 5a testing.
