Product details
Overview
1N5341BE3/TR8 from Microsemi is a 5.1 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply reference and overvoltage protection circuits. It delivers stable regulation at 240 mA test current with 1.5 Ω dynamic impedance and supports surge currents up to 14.4 A (8.3 ms half-sine).
For engineers reviewing the 1N5341BE3/TR8 datasheet, 1N5341BE3/TR8 pinout, 1N5341BE3/TR8 application, or 1N5341BE3/TR8 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), maximum regulator current (930 mA), reverse leakage (<1.0 µA at 3.9 V), and RoHS-compliant matte-tin plating.
Technical Context
This device operates as a two-terminal shunt voltage regulator, conducting in reverse breakdown when cathode voltage exceeds anode by ≥5.1 V. Its low dynamic impedance (1.5 Ω) ensures minimal voltage variation across 10–50% of IZM, and its 25 °C/W thermal resistance enables high-current operation with 3/8″ lead length heat sinking.
Designed for DC voltage stabilization, it exhibits tight regulation (ΔVZ = 0.39 V), withstands 14.4 A non-repetitive surges, and maintains performance from –65 °C to +150 °C. The T-18 package features void-free epoxy encapsulation (UL94V-0) and polarity indicated by cathode band.

FAQ
What is the Zener voltage tolerance of the 1N5341BE3/TR8?
The 1N5341BE3/TR8 has a Zener voltage tolerance of ±5%, as indicated by the "B" suffix in its part number. This means its nominal 5.1 V breakdown voltage falls within the range of 4.845 V to 5.355 V at 240 mA test current and 25 °C lead temperature. The e3 suffix confirms RoHS compliance but does not affect voltage tolerance.
How much power can the 1N5341BE3/TR8 dissipate continuously?
The 1N5341BE3/TR8 is rated for 5.0 W continuous power dissipation at 25 °C lead temperature (TL), with derating to zero at 150 °C. When mounted on FR4 with standard copper pads, its steady-state power drops to 1.47 W at 25 °C ambient. Its 25 °C/W junction-to-lead thermal resistance allows full 5 W operation with 3/8″ (10 mm) lead length acting as a heatsink.
What is the maximum reverse leakage current for the 1N5341BE3/TR8?
The 1N5341BE3/TR8 specifies a maximum reverse leakage current (IR) of 1.0 µA when tested at 3.9 V (VR = 0.77 × VZ). This low leakage ensures minimal quiescent current draw in clamp or reference configurations, supporting energy-efficient designs and accurate voltage sensing below the Zener knee.
Does the 1N5341BE3/TR8 have surge current capability?
Yes, the 1N5341BE3/TR8 is rated for a maximum non-repetitive surge current (IZSM) of 14.4 A, defined as the peak of an 8.3 ms half-sine waveform. This capability enables robust transient suppression in power rails and interface lines, protecting downstream components from short-duration overvoltage events without degradation.
What does the "TR8" suffix indicate in 1N5341BE3/TR8?
"TR8" indicates tape-and-reel packaging per EIA-296 standard, with 8 mm tape width and component orientation optimized for automated pick-and-place assembly. Combined with the "e3" RoHS suffix, 1N5341BE3/TR8 is configured for lead-free SMT production environments requiring traceable, machine-ready reels.
