Product details
Overview
1.5KE7V5A-T from Diodes Incorporated is a unidirectional 1500W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power lines and signal interfaces. It features a 6.40V reverse standoff voltage, 7.13V minimum breakdown voltage at 10mA test current, 11.3V maximum clamping voltage at 132A peak pulse current, and operates across –55°C to +175°C. It is used in automotive body control modules to protect CAN transceivers from ISO 7637-2 load dump surges.
For engineers reviewing the 1.5KE7V5A-T datasheet, 1.5KE7V5A-T pinout, 1.5KE7V5A-T application, or 1.5KE7V5A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under 1.0ms 8/20μs waveform, thermal derating above +25°C, and DO-201 axial lead compatibility with through-hole PCB layouts.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1.0ns) and stable breakdown characteristics. Its DO-201 package supports axial lead soldering per MIL-STD-202 Method 208 and provides 94V-0 flammability rating.
The device operates as a shunt protector: under normal conditions it presents <500μA leakage at 6.40V; during transient events exceeding 7.13V, it avalanches to clamp voltage ≤11.3V while conducting up to 132A peak pulse current for 1.0ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 1.0ms - sustains high-energy transients like ISO 7637-2 Pulse 5a without failure |
| Reverse Standoff Voltage (VRWM) | 6.40V - maximum continuous DC voltage before significant leakage; sets upper limit for protected circuit operating voltage |
| Breakdown Voltage (VBR) | 7.13V min @ 10mA - guaranteed avalanche initiation threshold; ensures reliable triggering before downstream IC damage |
| Clamping Voltage (VC) | 11.3V max @ 132A - limits voltage seen by protected IC during surge; must be below absolute maximum rating of load |
| Peak Pulse Current (IPP) | 132A @ 1.0ms - quantifies surge energy handling; derived from PPK/VC = 1500W/11.3V |
| Operating Temperature | –55°C to +175°C - enables use in under-hood automotive environments and industrial power supplies |
| Leakage Current (IR) | ≤500μA @ 6.40V - low standby loss; avoids excessive quiescent drain in battery-powered systems |
Pinout & Package
Package: DO-201 - axial-leaded, transfer-molded epoxy case rated UL 94V-0; 1.12g weight; moisture sensitivity level 1; tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during reverse-biased surge | Connected to ground or low-impedance return path; carries full IPP during clamping |
| Cathode | High-side connection to protected line | Marked with band; ties to supply rail or signal line requiring overvoltage protection |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures stable VBR over temperature and lifetime; eliminates passivation-related drift in harsh environments |
| 1500W peak pulse rating | Supports automotive load dump (ISO 7637-2 Pulse 5a) and lightning-induced surges in industrial I/O |
| Fast response time (<1.0ns) | Clamps before transient propagates into sensitive downstream circuitry; no added delay in protection path |
| RoHS-compliant, halogen-free "Green" design | Meets JESD22-A112 MSL Level 1; suitable for automotive PPAP and IATF 16949 manufacturing flows |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects 5V CAN transceiver power rail from load dump surges during alternator regulation failure. IC Role / Device Role: Shunt TVS placed between VCC and GND upstream of LDO regulator. Use Value: Clamps to 11.3V, keeping downstream 5V IC within its 6V absolute maximum rating while surviving 132A pulses. |
Use Scenario: Shields 24V digital input channel from field-wiring induced transients in factory automation cabinets. IC Role / Device Role: Primary overvoltage clamp on input node before optocoupler or Schmitt trigger. Use Value: Limits voltage to ≤11.3V during 1.0ms surges, preventing latch-up or gate oxide damage in interface ICs. |
| DC Power Supply Input Stage | Telecom Line Interface |
Use Scenario: Guards 12V SMPS front-end against coupling from adjacent AC/DC converter switching noise. IC Role / Device Role: Secondary protection after fuse and common-mode choke; placed across bulk capacitor terminals. Use Value: Absorbs repetitive 1500W pulses without parameter shift, maintaining long-term reliability in 24/7 operation. |
Use Scenario: Suppresses ESD and lightning-induced surges on -48V telecom battery feed lines. IC Role / Device Role: Unidirectional clamp referenced to system ground; coordinates with series impedance for impedance matching. Use Value: Withstands 132A peak current at -48V bias, enabling compliance with ITU-T K.20 and Telcordia GR-1089-CORE. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | 600W peak power, SMC package, 7.0V VRWM, 12.0V VC @ 53.3A | Lower power rating; surface-mount only; suited for space-constrained consumer electronics | Select when board area is limited and surge energy is ≤600W; verify thermal pad layout for SMB footprint |
| 1.5SMC7.0A | 1500W peak power, SMC package, 7.0V VRWM, 12.0V VC @ 125A | Same power rating but SMC surface-mount package; no axial leads; higher thermal resistance than DO-201 | Choose for automated assembly where through-hole insertion is unavailable; confirm PCB copper area meets θJA requirements |
Compared with 1.5KE7V5A-T, SMBJ7.0A offers smaller size but reduced surge capacity, while 1.5SMC7.0A matches power rating but sacrifices axial lead serviceability and thermal performance in high-ambient environments.

FAQ
What is the difference between 1.5KE7V5A-T and 1.5KE7V5CA-T?
The suffix 'C' denotes bidirectional configuration. 1.5KE7V5A-T is unidirectional (cathode-banded), intended for DC line protection with polarity-sensitive placement. 1.5KE7V5CA-T lacks cathode marking and clamps symmetrically for AC or dual-polarity signal lines. Their VRWM, VBR, and VC values differ slightly due to internal structure asymmetry.
Can 1.5KE7V5A-T be used in place of a 5.0V TVS diode?
No. Its 6.40V reverse standoff voltage exceeds typical 5V rail operating margins. Using it on a 5V line risks premature conduction during normal operation, increasing leakage and potential thermal runaway. A 5.0V-rated TVS such as SMAJ5.0A is required for proper margin.
Is 1.5KE7V5A-T compliant with AEC-Q200?
While not explicitly qualified to AEC-Q200 in public documentation, Diodes states that automotive-grade versions of the 1.5KE series are PPAP-capable and manufactured in IATF 16949-certified facilities. Customers requiring formal AEC-Q200 certification must contact Diodes directly for part-specific qualification status.
How does the DO-201 package affect thermal performance compared to SMC?
The DO-201's axial leads provide lower thermal resistance to ambient (θJA ≈ 50°C/W) versus SMC's surface-mount pads (θJA ≈ 70°C/W). This allows 1.5KE7V5A-T to sustain higher average power dissipation in high-temperature enclosures without derating, making it preferred for under-hood or sealed industrial applications.
