Product details
Overview
1N6296A-E3/51 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 110 V breakdown voltage (VBR min/max: 105–116 V), 94.0 V stand-off voltage (VWM), 152 V maximum clamping voltage at 9.9 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in industrial power supplies.
For engineers reviewing the 1N6296A-E3/51 datasheet, 1N6296A-E3/51 pinout, 1N6296A-E3/51 application, or 1N6296A-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge waveforms, thermal resistance data, and direct alternatives with documented parameter differences - all confirmed from Vishay's official 88301 specification document.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping behavior is characterized under 10/1000 µs waveform conditions, with derating applied above 25 °C ambient per Figure 2 of the datasheet.
The device exhibits a typical junction-to-lead thermal resistance of 15.4 °C/W and junction-to-ambient resistance of 75 °C/W, enabling effective heat dissipation in PCB-mounted applications without heatsinking up to 6.5 W continuous power. Forward voltage is specified as 5.0 V at 100 A for devices with VBR ≥ 250 V - not applicable to 1N6296A-E3/51 (VBR = 105–116 V), which follows the 3.5 V VF spec per Note (3).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V at 1.0 mA test current - defines reliable conduction onset threshold under DC stress |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 152 V at 9.9 A peak pulse current - clamping voltage during 10/1000 µs surge, limiting downstream voltage stress |
| PPPM | 1500 W - peak transient power handling capability, critical for lightning surge immunity (IEC 61000-4-5) |
| IPPM | 9.9 A - maximum non-repetitive surge current supported under standard 10/1000 µs waveform |
| TJ range | –55 °C to +175 °C - enables deployment in under-hood automotive, industrial motor drives, and outdoor power systems |
| RθJL | 15.4 °C/W - low thermal resistance from junction to lead supports reliable pulsed power dissipation without external heatsink |

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 (SMB) package; lower PPPM = 600 W; VC = 177 V @ 3.4 A; 20 % higher clamping voltage at rated current | Surface-mount only; unsuitable for through-hole legacy boards or high-energy surge environments requiring 1500 W | Select SMBJ110A only when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2 (1 kV) |
| 1.5KE110A | Same 1.5KE package and identical electrical specs; differs only in packaging suffix (E3/51 vs. E3/54) and reel quantity (1400 vs. 1400); RoHS compliant, commercial grade | No functional or application difference - fully interchangeable in design and qualification | Choose 1.5KE110A if standard tape-and-reel delivery (13″ diameter, 1400 pcs) is preferred over the 51-tray variant |
Compared with 1N6296A-E3/51, SMBJ110A offers SMT compatibility but sacrifices 60 % peak power handling and clamping performance, while 1.5KE110A provides identical protection characteristics in an alternate packaging format - making it a drop-in replacement where tray vs. reel logistics drive selection.

FAQ
What is the breakdown voltage tolerance for 1N6296A-E3/51?
The 1N6296A-E3/51 has a guaranteed breakdown voltage range of 105 V to 116 V at 1.0 mA test current, corresponding to ±5 % tolerance around the nominal 110 V rating. This tight VBR spread ensures predictable clamping onset across production lots and temperature extremes, critical for consistent overvoltage protection in safety-critical circuits.
Is 1N6296A-E3/51 suitable for bidirectional transient suppression?
No, 1N6296A-E3/51 is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the protected line. For bidirectional protection, Vishay specifies part numbers ending in "CA" (e.g., 1.5KE110CA). Using 1N6296A-E3/51 in reverse-biased AC applications risks permanent failure due to lack of symmetrical clamping capability.
What is the maximum clamping voltage of 1N6296A-E3/51 under surge conditions?
The maximum clamping voltage of 1N6296A-E3/51 is 152 V, measured at its rated peak pulse current of 9.9 A under the standard 10/1000 µs waveform. This value represents the highest voltage seen across the device during worst-case surge events and directly determines the protection level afforded to downstream components like MOSFETs or microcontrollers.
Does 1N6296A-E3/51 meet AEC-Q101 qualification?
No, 1N6296A-E3/51 is a commercial-grade part (E3 suffix) and is not AEC-Q101 qualified. For automotive applications requiring qualification, Vishay offers the HE3 suffix variant (e.g., 1.5KE110AHE3_B), which undergoes stress testing per AEC-Q101 Rev D and is marked with revision code "B" in the ordering code.
What is the thermal resistance from junction to lead for 1N6296A-E3/51?
The typical thermal resistance from junction to lead (RθJL) for 1N6296A-E3/51 is 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 PCB copper via the leads, supporting reliable operation at 6.5 W continuous power dissipation without additional heatsinking.
