Product details
Overview
1N6296A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 110 V breakdown voltage (VBR = 105–116 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 152 V at 9.9 A, 94.0 V maximum working voltage (VWM), and operates across –55 °C to +175 °C junction temperature range.
For engineers reviewing the 1N6296A-E3/54 datasheet, 1N6296A-E3/54 pinout, 1N6296A-E3/54 application, or 1N6296A-E3/54 equivalent, this device serves as a robust, glass-passivated, RoHS-compliant surge protector for automotive power supplies, industrial sensor interfaces, and telecom line protection where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101 qualification (in HE3 variants) are critical selection criteria.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for high-energy transient suppression with minimal response latency. Its 1500 W peak pulse rating is defined under JEDEC-standard 10/1000 µs waveform at 0.01% duty cycle, and it maintains stable clamping performance up to 175 °C junction temperature.
The device exhibits a temperature coefficient of VBR of +0.107 %/°C and delivers 152 V clamping voltage at 9.9 A peak pulse current. Its 94.0 V stand-off voltage ensures reliable blocking during normal operation while allowing rapid conduction above 105 V breakdown threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - Ensures consistent turn-on threshold across manufacturing lot and temperature; guarantees clamping activation before downstream IC damage. |
| VWM | 94.0 V - Maximum continuous reverse operating voltage; allows safe use on 72–80 V DC systems (e.g., 24 V/48 V industrial buses with 20% tolerance). |
| VC @ IPPM | 152 V at 9.9 A - Clamping voltage limits transient energy delivered to protected circuit; enables compatibility with 120 V-rated load switches and controllers. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; supports protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on medium-impedance lines. |
| IFSM | 200 A - Non-repetitive forward surge current rating (8.3 ms half-sine); withstands inrush or fault currents without bond wire failure. |
| TJ max. | +175 °C - Enables deployment in under-hood automotive environments and high-temperature industrial enclosures without derating. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements when used in high-duty-cycle or stacked layouts. |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and J-STD-002 solderability standards. Cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to system ground or low-side return path; defines polarity-sensitive placement in unidirectional configurations. |
| Cathode | Reverse-biased terminal (marked end) | Connected to protected line (e.g., +12 V rail); conducts during overvoltage events to shunt surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable long-term reliability and reduced leakage drift under thermal cycling and humidity stress. |
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against lightning-induced surges and inductive switching transients in industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | DO-214AA package; lower 600 W PPPM; 113 V VC @ 5.3 A; smaller footprint but lower surge capacity. | Better suited for space-constrained PCBs with moderate surge exposure (IEC 61000-4-5 Level 2). | Select SMBJ110A only if board area is critical and peak surge energy remains below 600 W; not drop-in for 1500 W requirements. |
| 1.5KE110A | Same DO-201AD package, identical electrical specs (VBR, VWM, VC, PPPM); differs only in packaging code (bulk vs. tape/reel) and RoHS compliance marking. | No functional difference; both meet same JEDEC 1.5KE family specifications and mechanical dimensions. | 1.5KE110A is functionally identical to 1N6296A-E3/54 and may be used interchangeably where E3/54 tape-and-reel delivery is not required. |
Compared with SMBJ110A, 1N6296A-E3/54 delivers 2.5× higher surge power handling in the same axial form factor, enabling single-device compliance with IEC 61000-4-5 Level 4. Against 1.5KE110A, it offers identical protection performance with guaranteed RoHS compliance and standardized reel packaging for automated assembly.

FAQ
What is the breakdown voltage range for the 1N6296A-E3/54?
The 1N6296A-E3/54 has a specified breakdown voltage (VBR) range of 105 V to 116 V at 1.0 mA test current. This tight tolerance ensures predictable turn-on behavior across temperature and production lots, making it suitable for precision overvoltage protection in 94 V-rated systems. The value is measured per JEDEC standard and confirmed in Vishay's official datasheet revision 09-Aug-2022.
Is the 1N6296A-E3/54 unidirectional or bidirectional?
The 1N6296A-E3/54 is a unidirectional Transient Voltage Suppressor. Its polarity is marked by a cathode band, and it conducts only when the cathode is at a higher potential than the anode. Bidirectional variants in this family carry a "CA" suffix (e.g., 1.5KE110CA); the absence of "C" in 1N6296A-E3/54 confirms its unidirectional configuration.
What is the clamping voltage of the 1N6296A-E3/54 at its rated peak pulse current?
The 1N6296A-E3/54 clamps to a maximum of 152 V at its peak pulse current (IPPM) of 9.9 A, tested with a 10/1000 µs waveform. This clamping voltage directly determines the maximum stress imposed on downstream components during surge events and is validated per JEDEC test conditions in the official Vishay datasheet.
Does the 1N6296A-E3/54 meet automotive qualification standards?
The base 1N6296A-E3/54 is RoHS-compliant and qualified for commercial use. For automotive applications, Vishay offers the AEC-Q101-qualified variant 1.5KE110AHE3_B (or equivalent HE3 suffix part), which shares identical electrical specs but undergoes additional stress testing. The E3/54 version itself is not AEC-Q101 certified.
What package type does the 1N6296A-E3/54 use?
The 1N6296A-E3/54 uses the DO-201AD package (Case Style 1.5KE), an axial-leaded, epoxy-molded outline with 0.375" (9.5 mm) lead length. It complies with UL 94 V-0 flammability rating and features matte tin-plated leads meeting J-STD-002 solderability requirements. Dimensions are fully specified in Vishay document 88301.
