Product details
Overview
1N5341E3/TR8 from Microsemi is a 6.2 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply feedback loops, overvoltage protection circuits, and precision reference applications. It delivers 765 Ω dynamic impedance at 200 mA test current, supports 765 mA maximum Zener current with adequate heat sinking, and operates across –65°C to +150°C.
For engineers reviewing the 1N5341E3/TR8 datasheet, 1N5341E3/TR8 pinout, 1N5341E3/TR8 application, or 1N5341E3/TR8 equivalent, key selection criteria include its 6.2 V nominal Zener voltage, 5 W steady-state power rating at lead temperature <25°C, ±5% tolerance (B-suffix equivalent), low 0.10 V voltage regulation (ΔVZ), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse-biased current above its specified Zener breakdown threshold. Its 25 °C/W junction-to-lead thermal resistance enables high-current operation when mounted with ≥10 mm lead length from body.
The 1N5341E3/TR8 exhibits minimal voltage variation versus current-0.10 V ΔVZ between 10% and 50% of IZM-and maintains tight regulation under transient surge conditions up to 200 A peak (8.3 ms half-sine), making it suitable for industrial power rail stabilization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same 6.2 V, ±5%, 5 W rating but SnPb lead finish; not RoHS-compliant | Acceptable where legacy Pb-based soldering is used; unsuitable for new RoHS designs | Select 1N5341B only if Pb-containing process flow is mandated and e3 compliance is waived |
| MMSZ5234B-TP | Surface-mount SOD-123 package; 6.2 V, ±5%, 500 mW only; 10× lower power rating | Not interchangeable for high-current regulation; limited to low-power bias/reference roles | Choose MMSZ5234B-TP only for space-constrained PCBs where IZ ≤ 81 mA and thermal mass is insufficient for axial devices |
Compared with 1N5341B and MMSZ5234B-TP, the 1N5341E3/TR8 uniquely combines RoHS compliance, 5 W power handling, axial-leaded mechanical robustness, and industry-standard JEDEC T-18 packaging-making it the preferred choice for industrial-grade power regulation where reliability, thermal margin, and regulatory compliance are jointly critical.

FAQ
What is the Zener voltage tolerance of the 1N5341E3/TR8?
The 1N5341E3/TR8 has a ±5% Zener voltage tolerance, consistent with the B-suffix designation in the 1N53xxB family. This means its actual breakdown voltage falls between 5.89 V and 6.51 V at 200 mA test current and 25°C lead temperature, as verified in Microsemi's official datasheet revision D (2008).
Does the 1N5341E3/TR8 require dry packing before reflow soldering?
No, the 1N5341E3/TR8 does not require dry packing. Its moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1, meaning it can be stored and processed indefinitely at ambient conditions without baking or humidity-controlled packaging prior to soldering.
What is the maximum surge current rating for the 1N5341E3/TR8?
The 1N5341E3/TR8 is rated for a maximum non-recurrent surge current (IZSM) of 200 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating is confirmed in the "Electrical Characteristics" table on page 1 of the Microsemi datasheet and applies under specified mounting and thermal conditions.
Can the 1N5341E3/TR8 be used as a direct replacement for the 1N5341B?
Yes, the 1N5341E3/TR8 is functionally identical to the 1N5341B in all electrical and thermal specifications-including 6.2 V Zener voltage, ±5% tolerance, 5 W power rating, and 765 mA IZM. The only difference is RoHS-compliant matte-tin plating (e3) versus SnPb finish on the 1N5341B; no PCB layout change is needed.
What is the voltage regulation (ΔVZ) specification for the 1N5341E3/TR8?
The 1N5341E3/TR8 has a maximum voltage regulation (ΔVZ) of 0.10 V, defined as the difference between Zener voltage measured at 10% and 50% of IZM (76.5 mA and 382.5 mA). This parameter reflects its excellent line regulation performance under varying load currents.
