Product details
Overview
1.5KE7.5CA-T-F from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, designed for overvoltage protection of DC power lines and signal interfaces. It features a 6.40V reverse standoff voltage, 7.13–7.88V breakdown range at 10mA test current, 11.3V max clamping voltage at 132A peak pulse current, and operates from –55°C to +175°C.
For engineers reviewing the 1.5KE7.5CA-T-F datasheet, 1.5KE7.5CA-T-F pinout, 1.5KE7.5CA-T-F application, or 1.5KE7.5CA-T-F equivalent, key selection criteria include clamping ratio (VC/VRWM ≈ 1.77), unidirectional/bidirectional configuration, DO-201 axial lead compatibility, and AEC-Q200 readiness for automotive ECU and infotainment power rail protection.
Technical Context
This bidirectional TVS diode uses glass-passivated silicon junctions to achieve fast sub-nanosecond response to ESD and lightning-induced transients. Its symmetrical I-V curve enables suppression of both positive and negative polarity surges without polarity-sensitive placement on PCBs.
The device sustains 1500W peak pulse power (10/1000μs waveform) with 11.3V clamping at 132A, delivering low let-through energy to downstream ICs. Thermal derating begins above +25°C ambient, and its 0.061%/°C VBR temperature coefficient ensures stable clamping across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W - Withstands 10/1000μs surge events common in automotive load-dump and ISO 7637-2 tests. |
| Reverse Standoff Voltage | 6.40 V - Maximum continuous DC or RMS voltage before significant leakage; sets operating margin below breakdown. |
| Breakdown Voltage Range | 7.13–7.88 V @ 10 mA - Confirmed conduction onset window; ensures reliable triggering under worst-case tolerance and temp drift. |
| Max Clamping Voltage | 11.3 V @ 132 A - Voltage seen by protected circuit during full-rated surge; defines minimum safe headroom for 12V systems. |
| Peak Pulse Current | 132 A - Surge current capacity at rated clamping voltage; validates compliance with IEC 61000-4-5 Level 4 (4kV) |
| Operating Temperature | –55°C to +175°C - Supports under-hood automotive, industrial motor drives, and high-temp power supply designs. |
| Leakage Current | ≤500 μA @ 6.40 V - Low standby loss critical for battery-powered and always-on circuits. |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with transfer-molded epoxy body (UL 94V-0), 1.12g mass, and tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point in forward bias; symmetrical terminal in bidirectional operation | No polarity marking required; either lead may connect to line or ground depending on layout symmetry needs. |
| Cathode (Lead 2) | Current exit point in forward bias; symmetrical terminal in bidirectional operation | Identical electrical behavior to Anode; bidirectional clamping eliminates need for orientation-aware placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable, repeatable breakdown characteristics and long-term reliability under repeated surge stress. |
| Bidirectional configuration (suffix "C") | Protects AC-coupled signals and dual-polarity rails without external polarity management or discrete back-to-back diodes. |
| 1500W peak pulse rating | Meets stringent automotive load-dump immunity (SAE J1128, ISO 16750-2) and industrial surge standards (IEC 61000-4-5). |
| RoHS-compliant, halogen-free "Green" finish | Complies with EU RoHS 3 (2015/863/EU), <900 ppm Br/Cl, <1000 ppm Sb; supports eco-design and export compliance. |
| Moisture sensitivity Level 1 | Eliminates bake requirements prior to reflow or wave soldering; simplifies manufacturing flow for high-volume assembly. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
|
Use Scenario: Protects 12V supply rail of BCM microcontroller and CAN transceivers against load-dump transients up to 35V/100ms. IC Role / Device Role: Primary overvoltage clamp placed directly at power entry point before LDO regulators. Use Value: Limits rail voltage to ≤11.3V during 132A surge, preventing latch-up or permanent damage to 16V-rated logic ICs. |
Use Scenario: Shields 24V digital input optocouplers and FPGA I/O banks from field-wiring induced surges in factory automation. IC Role / Device Role: Front-end transient suppressor on dry-contact or PNP/NPN sensor inputs. Use Value: Clamps induced spikes to 11.3V while maintaining <500μA leakage at 24V nominal, ensuring clean logic thresholds. |
| Telecom Power Feeding Interface | Medical Patient Monitor Power Entry |
|
Use Scenario: Guards PoE+ (IEEE 802.3at) 57V DC feed lines against lightning-induced common-mode surges on outdoor Ethernet runs. IC Role / Device Role: Secondary-level TVS in conjunction with gas discharge tube (GDT) front-end for staged protection. Use Value: Provides low-clamp, fast-response stage that handles residual energy after GDT fires, limiting let-through to safe levels for DC/DC controllers. |
Use Scenario: Secures isolated 5V/3.3V auxiliary power rails feeding analog front-end ADCs and patient isolation barriers. IC Role / Device Role: Final-stage protector on low-voltage secondary side where leakage and capacitance must be minimized. Use Value: Delivers 11.3V clamping with negligible parasitic capacitance (<100pF typical), avoiding signal integrity degradation in high-resolution biosignal paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Lower 600W peak power; SMB surface-mount package; 7.0V standoff; 12.6V clamping at 47.6A | Targeted at space-constrained consumer electronics; insufficient for automotive load-dump compliance | Select when board area is limited and surge threat level is IEC 61000-4-2 only (not 4-5) |
| 1.5SMC7.0CA | Same 1500W rating but SMC package; 7.0V standoff; 12.6V clamping at 119A; higher thermal resistance than DO-201 | Better suited for automated SMT assembly; requires thermal relief pads for sustained power dissipation | Choose for SMT production lines where axial leads are incompatible with pick-and-place workflow |
Compared with SMBJ7.0CA and 1.5SMC7.0CA, the 1.5KE7.5CA-T-F delivers superior surge robustness in through-hole form factor, lower clamping ratio (1.77 vs. 1.80), and proven DO-201 mechanical reliability in high-vibration environments-making it optimal for automotive and industrial power entry points.

FAQ
What does the "CA" suffix indicate in 1.5KE7.5CA-T-F?
The "CA" suffix denotes a bidirectional TVS diode configuration, meaning it provides symmetrical clamping for both positive and negative voltage transients. This eliminates polarity-dependent placement on PCBs and enables protection of AC-coupled signals or dual-rail systems without additional components.
Is 1.5KE7.5CA-T-F suitable for automotive applications?
Yes-this part meets AEC-Q200 stress testing requirements when manufactured in IATF 16949-certified facilities. Its –55°C to +175°C operating range, 1500W peak pulse rating, and DO-201 mechanical robustness make it appropriate for engine control units, lighting modules, and infotainment power rails subject to load-dump and jump-start conditions.
How does the clamping voltage of 11.3V relate to system protection design?
The 11.3V clamping voltage is measured at 132A peak pulse current (10/1000μs waveform). To ensure downstream IC survival, designers must verify that the protected IC's absolute maximum voltage rating exceeds 11.3V with margin-typically ≥13.2V for 12V systems-and confirm that PCB trace inductance does not cause overshoot beyond clamping level during fast-rising transients.
What is the significance of the "T-F" suffix in the full part number?
The "T-F" suffix indicates tape-and-reel packaging (1k units per reel) with lead-free, RoHS-compliant, halogen-free "Green" finish. "T" specifies 13-inch tape-and-reel format compatible with standard SMT feeders; "F" confirms compliance with Diodes Incorporated's environmental specifications per EU Directive 2015/863/EU and internal green material definitions.
