Product details
Overview
1N5341CE3/TR12 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/TR12 datasheet, 1N5341CE3/TR12 pinout, 1N5341CE3/TR12 application, or 1N5341CE3/TR12 equivalent, key selection criteria include Zener voltage tolerance (±2%), maximum surge current (765 A), thermal resistance (25 °C/W junction-to-lead), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage reference where reverse-biased operation maintains a stable 6.2 V across its terminals within ±2% tolerance. Its low 1.0 Ω dynamic impedance at 200 mA ensures minimal voltage deviation under load variation, and its 25 °C/W junction-to-lead thermal resistance enables reliable 5 W dissipation with standard 3/8″ lead length heat sinking.
The 1N5341CE3/TR12 exhibits 0.10 V voltage regulation (ΔVZ) between 10% and 50% of IZM, confirming tight regulation stability across operating current range. Its cathode band marking and axial T-18 package support through-hole mounting in industrial power supplies and analog instrumentation requiring traceable, screened components.

FAQ
What is the Zener voltage tolerance of the 1N5341CE3/TR12?
The 1N5341CE3/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 6.2 V Zener voltage is guaranteed between 6.076 V and 6.324 V at 200 mA test current and 25°C lead temperature. This tighter tolerance supports higher-accuracy regulation than the ±5% 1N5341B variant, making the 1N5341CE3/TR12 suitable for applications demanding stable reference performance without external trimming.
Does the 1N5341CE3/TR12 require dry packing before use?
No, the 1N5341CE3/TR12 does not require dry packing. It carries moisture sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and handled indefinitely at ambient conditions without baking or humidity-controlled packaging. This simplifies manufacturing logistics and eliminates floor-life tracking for the 1N5341CE3/TR12 in surface mount or through-hole assembly lines.
What is the maximum surge current rating for the 1N5341CE3/TR12?
The 1N5341CE3/TR12 is rated for a maximum non-recurrent surge current (IZSM) of 765 A, specified as the peak of an 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy without parametric shift or catastrophic failure, making the 1N5341CE3/TR12 appropriate for clamping lightning-induced surges or switching transients in industrial power rails.
How is polarity marked on the 1N5341CE3/TR12?
The 1N5341CE3/TR12 uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode to operate in Zener breakdown mode. During circuit operation, the cathode connects to the regulated node (e.g., feedback input or protected rail), while the anode connects to ground or lower-potential reference. Reversing this connection forward-biases the diode and invalidates regulation.
Is the 1N5341CE3/TR12 suitable for RoHS-compliant manufacturing?
Yes, the 1N5341CE3/TR12 is RoHS compliant, confirmed by the "e3" suffix in its part number. Its leads feature annealed matte-tin plating per MIL-STD-750 Method 2026, ensuring compatibility with lead-free soldering processes up to 260°C for 10 seconds. This makes the 1N5341CE3/TR12 fully qualified for environmentally regulated production environments without process modification.
