Product details
Overview
1N5341CE3/TR8 from Microsemi is a 6.2 V, ±2% tolerance, 5 W axial-leaded silicon Zener diode optimized for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation. It delivers stable regulation at 200 mA test current with 1.0 Ω dynamic impedance and operates across –65°C to +150°C.
For engineers reviewing the 1N5341CE3/TR8 datasheet, 1N5341CE3/TR8 pinout, 1N5341CE3/TR8 application, or 1N5341CE3/TR8 equivalent, key selection criteria include its tight ±2% VZ tolerance, low 1.0 Ω ZZ at IZT, 765 mA maximum Zener current (IZM), RoHS-compliant matte-tin plating, and T-18 axial package compatibility with manual or wave soldering per MIL-STD-750.
Technical Context
This device functions as a two-terminal shunt regulator, maintaining a stable 6.2 V reverse breakdown voltage across a wide operating current range (10%–50% of IZM). Its voltage regulation (ΔVZ) is specified at 0.10 V, reflecting minimal variation between 10% and 50% of rated Zener current.
The 1N5341CE3/TR8 features a thermal resistance of 25 °C/W junction-to-lead (at 10 mm lead length) and 85 °C/W junction-to-ambient on FR4, enabling reliable 5 W operation with appropriate heat sinking. Polarity is marked by a cathode band; operation requires the banded end to be positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±2% - precise reference voltage for feedback and clamping applications |
| Test Current (IZT) | 200 mA - defines nominal operating point for VZ and ZZ measurement |
| Dynamic Impedance (ZZ) | 1.0 Ω max at IZT - ensures minimal output voltage shift under load transients |
| Max Zener Current (IZM) | 765 mA - maximum continuous DC current at 25°C with adequate heatsinking |
| Power Dissipation (PD) | 5.0 W at TL = 25°C - steady-state rating with 10 mm lead length from body |
| Operating Temperature | –65°C to +150°C - supports industrial and aerospace environments without derating |
| Reverse Leakage (IR) | 10 µA max at VR = 3.0 V - low off-state current preserves efficiency in standby modes |

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 nominal VZ, but ±5% tolerance (B suffix) vs. ±2% (C suffix) | Lower accuracy; suitable where cost priority outweighs regulation precision | Select 1N5341B only if ±5% VZ meets system tolerance budget |
| MMSZ5234BT1G | Surface-mount SOD-123 package; 6.2 V ±5%; 500 mW rating; ZZ = 7 Ω | Not drop-in; requires PCB redesign; limited to low-power applications | Choose MMSZ5234BT1G only for space-constrained, low-current designs where axial leads are impractical |
Compared with 1N5341B and MMSZ5234BT1G, the 1N5341CE3/TR8 offers superior voltage accuracy (±2% vs. ±5%), higher power handling (5 W vs. 0.5 W), and lower dynamic impedance (1.0 Ω vs. 7 Ω), making it optimal for high-stability, high-current regulation where thermal management is feasible.

FAQ
What is the Zener voltage tolerance of the 1N5341CE3/TR8?
The 1N5341CE3/TR8 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its measured VZ at 200 mA test current falls within 6.076 V to 6.324 V at 25°C. The tighter tolerance enables higher accuracy in feedback and reference applications compared to ±5% (B suffix) or ±10% (A suffix) variants of the same 6.2 V rating.
Does the 1N5341CE3/TR8 require dry packing before use?
No, the 1N5341CE3/TR8 does not require dry packing. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it has no floor life limitation and can be stored and assembled without baking or humidity-controlled packaging. This simplifies logistics and eliminates moisture-related rework risk during wave or hand soldering.
What is the maximum surge current rating for the 1N5341CE3/TR8?
The 1N5341CE3/TR8 has a maximum non-recurrent surge current (IZSM) rating of 200 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient overvoltage energy without failure, making it suitable for clamping inductive kickback or lightning-induced surges in industrial control and power conversion systems.
How is polarity identified on the 1N5341CE3/TR8?
Polarity on the 1N5341CE3/TR8 is indicated by a single color band near one end of the axial package - this is the cathode terminal. For proper Zener operation, the banded (cathode) end must be held at a higher potential than the unbanded (anode) end. Reversing polarity places the device in forward conduction, where it behaves as a standard silicon diode with ~1.2 V forward drop at 1 A.
Can the 1N5341CE3/TR8 be used in surface-mount designs?
No, the 1N5341CE3/TR8 is an axial-leaded T-18 (DO-41) package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5341B (SMB package, 5 W) or MMSZ5234BT1G (SOD-123, 500 mW). Substituting the 1N5341CE3/TR8 into an SMT footprint would require mechanical adaptation and is not recommended due to thermal and reliability risks.
