Overview
1.5KE75C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.6 A peak pulse current (IPPM), and clamps to ≤104 V at rated surge - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5KE75C-E3/54 datasheet, 1.5KE75C-E3/54 pinout, 1.5KE75C-E3/54 application, or 1.5KE75C-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, bidirectional clamping behavior, thermal derating curves, and direct alternatives with documented differences in VBR, IPPM, and qualification status.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities. Its 104 V maximum clamping voltage at 14.6 A ensures reliable protection of downstream MOSFETs and ICs against lightning-induced surges and inductive switching transients.
Rated for -55 °C to +175 °C junction temperature, it exhibits 0.105 %/°C temperature coefficient of VBR and 15.4 °C/W junction-to-lead thermal resistance - enabling stable performance under high ambient conditions without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V - defines guaranteed avalanche conduction onset range under 1 mA test current; critical for margin-based system-level surge immunity design. |
| VWM | 64.1 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets upper limit for normal-mode operating voltage. |
| IPPM | 14.6 A - peak surge current survivable with 10/1000 µs waveform; determines minimum trace width and PCB layout clearance for transient path. |
| VC (max) | 104 V - clamped voltage at IPPM; directly limits stress on protected IC's absolute maximum rating (e.g., 120 V-rated gate drivers). |
| PPPM | 1500 W - peak pulse power handling capability; enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges. |
| TJ max | +175 °C - maximum junction temperature; supports operation in under-hood automotive or enclosed industrial enclosures without forced airflow. |
| Leakage (ID) | 1 µA at VWM - ultra-low reverse leakage preserves battery life in always-on circuits and avoids false triggering in high-impedance sensing nodes. |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded molded epoxy body, RoHS-compliant matte tin-plated leads. Dimensions: 5.3 mm diameter × 9.5 mm length (0.210" × 0.375"), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal in bidirectional configuration | Connected to circuit ground or common return; forms symmetrical clamp path with cathode during either polarity surge. |
| Cathode | High-side reference terminal in bidirectional configuration | Connected to protected line (e.g., CAN_H, RS-485 A); conducts during positive or negative transients relative to Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics over 1000+ surge events without parameter drift or degradation. |
| 1500 W peak pulse power (10/1000 µs) | Supports single-device compliance with IEC 61000-4-5 Ed.3 surge immunity up to 4 kV (2 Ω source impedance) without parallel staging. |
| Fast response time (~1 ns) | Clamps transients before sensitive logic or analog circuitry experiences destructive overvoltage - faster than MOVs or GDTs. |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive-grade reliability requirements including HTOL, TC, and ESD testing per AEC-Q101 Rev D. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving protection margin for sub-100 V logic rails. |

FAQ
What is the polarity configuration of the 1.5KE75C-E3/54?
The 1.5KE75C-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive- and negative-going transients. Unlike unidirectional variants (e.g., 1.5KE75A-E3/54), it has no cathode marking and functions identically regardless of voltage polarity applied across its terminals - essential for protecting AC-coupled or differential signal lines like RS-485 or CAN.
Does the 1.5KE75C-E3/54 meet AEC-Q101 qualification?
No, the 1.5KE75C-E3/54 is commercial-grade only. AEC-Q101 qualification applies only to variants with the HE3 suffix (e.g., 1.5KE75CAHE3_B). The "E3" suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance, but does not include the extended temperature cycling, HTRB, or ESD testing required for automotive qualification.
What is the maximum clamping voltage of the 1.5KE75C-E3/54 at its rated peak pulse current?
The 1.5KE75C-E3/54 clamps to a maximum of 104 V at its rated peak pulse current of 14.6 A (10/1000 µs waveform). This value is measured per Figure 7 in Vishay Document 88301 and represents the worst-case voltage seen by downstream circuitry during full-rated surge events - a key parameter for verifying compatibility with protected ICs' absolute maximum ratings.
Can the 1.5KE75C-E3/54 be used in parallel to increase surge handling capacity?
Yes, multiple 1.5KE75C-E3/54 devices can be paralleled to increase total peak pulse power dissipation, but only with careful attention to matching VBR (±5 % recommended) and symmetrical PCB layout. Mismatched units may share current unevenly, causing premature failure of the lowest-VBR device. Derating guidelines in Figure 2 of the datasheet must be followed for multi-device configurations.
What is the thermal resistance from junction to lead (RθJL) for the 1.5KE75C-E3/54?
The 1.5KE75C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as specified in the Thermal Characteristics table of Vishay Document 88301. This low value enables efficient heat transfer from the silicon die to the PCB copper via the axial leads - supporting reliable operation at elevated ambient temperatures when mounted with ≥9.5 mm lead length.
