Product details
Overview
1.5KE7.5C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 7.13 V to 7.88 V breakdown voltage (VBR) at 10 mA, 6.40 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), clamping voltage of 11.3 V at 133 A peak pulse current, and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5KE7.5C-E3/54 datasheet, 1.5KE7.5C-E3/54 pinout, 1.5KE7.5C-E3/54 application, or 1.5KE7.5C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.59), JEDEC 1.5KE package compatibility, AEC-Q101 qualification eligibility (HE3 variant), and UL 94 V-0 molded epoxy construction.
Technical Context
This TVS diode employs a glass passivated silicon junction optimized for sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions with 0.01% duty cycle, and maintains stable clamping performance up to 175 °C junction temperature. Thermal resistance is specified at RθJL = 15.4 °C/W (junction-to-lead), supporting high-reliability mounting on PCB copper pours or leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines precise voltage threshold where clamping initiates reliably |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 500 µA |
| VC @ IPPM | 11.3 V at 133 A - clamped voltage during full 1500 W transient, limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power handling per 10/1000 µs waveform, enabling protection against severe lightning surges |
| IPPM | 133 A - maximum non-repetitive surge current the device sustains without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | Lower peak power (600 W), smaller SMB package (surface-mount), tighter VBR tolerance (5%), lower IPPM (62.7 A) | Suitable for space-constrained PCBs but requires parallel devices for 1500 W-level protection | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5KE7.5CA | Same electrical specs and DO-201AD package; differs only in packaging suffix (E3/54 = tape-and-reel, CA = base part number without reel code) | No functional difference - identical device, differing only in ordering format and traceability | Choose 1.5KE7.5CA for prototype builds or distributor stock; 1.5KE7.5C-E3/54 for production volume with automated assembly |
Compared with SMBJ7.0CA, 1.5KE7.5C-E3/54 provides 2.5× higher surge power handling and axial-leaded mechanical robustness for high-vibration environments; compared with 1.5KE7.5CA, it adds reel packaging and traceable lot coding for SMT line integration and quality control.

FAQ
What is the breakdown voltage range of the 1.5KE7.5C-E3/54?
The 1.5KE7.5C-E3/54 has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per JEDEC standards. This tight 5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 5 V and 3.3 V logic interfaces without false triggering.
Is the 1.5KE7.5C-E3/54 unidirectional or bidirectional?
The 1.5KE7.5C-E3/54 is a bidirectional TVS diode, indicated by the "C" suffix. It provides symmetrical clamping for both positive and negative transients, eliminating polarity concerns during PCB layout. Unlike unidirectional types (e.g., 1.5KE7.5A), it has no cathode band and functions identically regardless of terminal orientation.
Does the 1.5KE7.5C-E3/54 meet automotive qualification standards?
The base 1.5KE7.5C-E3/54 is commercial-grade; however, the AEC-Q101 qualified variant is 1.5KE7.5CHE3_B (with "HE3" and revision code). That version undergoes stress testing per AEC-Q101 for automotive use, while 1.5KE7.5C-E3/54 itself is RoHS-compliant and suitable for industrial and telecom applications where automotive qualification is not mandated.
What is the clamping voltage of the 1.5KE7.5C-E3/54 at maximum surge current?
At its rated peak pulse current of 133 A (10/1000 µs waveform), the 1.5KE7.5C-E3/54 clamps to a maximum of 11.3 V. This low clamping ratio (VC/VBR ≈ 1.59) minimizes voltage overshoot on protected circuits, making it effective for safeguarding 5 V-tolerant ICs and MOSFET gates without additional series impedance.
What package type does the 1.5KE7.5C-E3/54 use, and what are its mechanical dimensions?
The 1.5KE7.5C-E3/54 uses the JEDEC DO-201AD axial package (Case Style 1.5KE), with a molded epoxy body meeting UL 94 V-0 flammability rating. Key dimensions include 1.0 inch (25.4 mm) minimum body length, 0.375 inch (9.5 mm) lead length, and 0.042 inch (1.07 mm) lead diameter - compatible with standard through-hole wave soldering and manual assembly.
