Product details
Overview
1.5KE7V5CA-T from Diodes Incorporated is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 6.40V reverse standoff voltage, 7.13–7.88V breakdown voltage at 10mA, and 11.3V clamping voltage at 132A peak pulse current. It protects DC power rails and signal lines in automotive body electronics against ESD and lightning-induced surges.
For engineers reviewing the 1.5KE7V5CA-T datasheet, 1.5KE7V5CA-T pinout, 1.5KE7V5CA-T application, or 1.5KE7V5CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current capability under 1.0ms 8/20μs waveform, bidirectional surge handling for AC-coupled or floating interfaces, and DO-201 axial-leaded mechanical compatibility with manual or wave-soldered PCB layouts.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC signals, differential buses, or ungrounded circuits without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500μA at 6.40V) over temperature.
The device responds within <1.0ns to transients, clamping voltages to ≤11.3V at 132A (1.0ms pulse), and maintains thermal stability up to +175°C junction temperature. Its 1.12g mass and UL 94V-0 epoxy package support high-reliability industrial and automotive under-hood deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W (1.0ms, non-repetitive, defines maximum surge energy absorption) |
| Reverse Standoff Voltage (VRWM) | 6.40V (maximum continuous working voltage before significant leakage) |
| Breakdown Voltage (VBR) | 7.13–7.88V @ 10mA (guaranteed conduction onset range for reliable triggering) |
| Clamping Voltage (VC) | 11.3V @ 132A IPP (voltage seen by protected circuit during worst-case surge) |
| Peak Pulse Current (IPP) | 132A (maximum single-event surge current survivable at 1.0ms pulse width) |
| Operating Temperature | −55°C to +175°C (supports under-hood automotive and industrial environments) |
| Leakage Current (IR) | ≤500μA @ 6.40V (low standby power loss and minimal loading on source) |
Pinout & Package
Package: DO-201 axial-leaded through-hole package with tin-finished leads, UL 94V-0 transfer-molded epoxy body, and 1.12g mass. Marking: "1.5KE7V5CA" only (bidirectional devices omit cathode band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative polarity) | Connects to line or node requiring protection; symmetrical with Cathode for bidirectional operation |
| Cathode | Surge current entry (positive polarity) | Connects to line or node requiring protection; identical electrical behavior to Anode in bidirectional configuration |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures consistent VBR tolerance and long-term reliability under thermal cycling |
| Bidirectional surge suppression | Enables single-device protection of AC-coupled interfaces like RS-485 or CAN without external polarity management |
| 1500W peak pulse rating | Supports IEC 61000-4-5 Level 4 (4kV line-to-line, 2Ω source impedance) compliance with margin |
| RoHS-compliant, halogen-free "Green" finish | Meets automotive AEC-Q200 environmental requirements and global regulatory mandates |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and door module microcontrollers from load-dump and jump-start transients. IC Role / Device Role: Bidirectional clamping element placed between LIN line and ground, absorbing ±100V spikes. Use Value: Maintains signal integrity below 11.3V clamping while surviving 132A pulses-preventing latch-up or damage to 5V-tolerant transceivers. | Use Scenario: Safeguarding 4–20mA current-loop sensor inputs against field-wiring induced surges in factory automation cabinets. IC Role / Device Role: Primary overvoltage clamp across input terminals, shunting surge energy before it reaches precision op-amps and ADC front-ends. Use Value: 6.40V VRWM allows direct placement on 24V loop supply rails without false triggering; 1500W rating handles multi-kV transients from relay coil switching. |
| AC-DC Power Supply EMI Filter Stage | USB 2.0 Data Line Surge Suppression |
Use Scenario: Suppressing common-mode surges entering via AC mains input before bridge rectifier and bulk capacitor. IC Role / Device Role: Bidirectional TVS connected between L-N and L/N-to-earth to clamp differential and common-mode transients. Use Value: Symmetrical 6.4V standoff enables balanced clamping on both AC half-cycles; DO-201 axial form factor fits high-voltage creepage spacing requirements. | Use Scenario: Protecting USB D+/D− lines from ESD events (>±15kV contact discharge per IEC 61000-4-2) in portable docking stations. IC Role / Device Role: Low-capacitance bidirectional clamp placed directly at USB connector, referenced to system ground. Use Value: 11.3V clamping ensures downstream PHY ICs (typically 3.3V tolerant) remain within safe operating area during fast-rising ESD strikes. |
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 peak power (600W), smaller SMB package, 7.0V VRWM, 11.2V VC @ 53.6A | Designed for surface-mount space-constrained designs; insufficient for 1500W IEC 61000-4-5 Level 4 | Select when board space is limited and surge threat level is ≤Level 2 (1kV) |
| 1N6267A | Same DO-201 package, 1500W rating, but unidirectional; 6.4V VRWM, 10.5V VC @ 143A | Requires explicit polarity orientation; unsuitable for AC or floating nodes without additional diodes | Choose only for DC rail protection where polarity is fixed and lower clamping voltage is critical |
Compared with SMBJ7.0CA and 1N6267A, the 1.5KE7V5CA-T uniquely delivers bidirectional 1500W surge handling in a through-hole DO-201 package-enabling robust, polarity-agnostic protection for automotive and industrial systems where mechanical reliability and high-energy transient immunity are mandatory.

FAQ
What does the "CA" suffix indicate in 1.5KE7V5CA-T?
The "CA" suffix denotes a bidirectional configuration: the device provides symmetrical clamping for both positive and negative transients without polarity dependence. Unlike unidirectional "A" variants (e.g., 1.5KE7V5A), it has no cathode marking and functions identically in either orientation-ideal for AC-coupled or floating signal lines such as RS-485 or CAN bus stubs.
Can 1.5KE7V5CA-T be used in place of a unidirectional TVS like 1.5KE7V5A?
Yes, but only if circuit topology permits bidirectional clamping. The 1.5KE7V5CA-T replaces unidirectional parts in applications where polarity is undefined or alternating-such as transformer-coupled interfaces-but cannot substitute in DC rail protection where cathode must be tied to higher potential. Its clamping voltage (11.3V) is slightly higher than the unidirectional 1.5KE7V5A (10.5V), affecting margin for 5V systems.
Is 1.5KE7V5CA-T compliant with AEC-Q200 for automotive use?
While Diodes Incorporated manufactures the 1.5KE series in IATF 16949-certified facilities and supports PPAP, the 1.5KE7V5CA-T itself is not individually AEC-Q200 qualified. For automotive applications requiring formal qualification, Diodes recommends contacting their sales team for AEC-Q200-compliant alternatives such as the P6SMBJ7.0CA-Q or SMAJ7.0CA-Q series with full stress-test documentation.
How does the DO-201 package affect thermal performance compared to SMC or SMB packages?
The DO-201's axial-leaded construction provides superior thermal mass and PCB heat spreading versus surface-mount packages-enabling higher sustained power dissipation (5.0W at TL = 75°C) and improved reliability under repeated surge stress. However, its larger footprint and through-hole mounting require more board area and assembly steps than SMC/SMB equivalents, making it preferred for high-reliability industrial and under-hood automotive rather than compact consumer designs.
