Product details
Overview
1N5340CE3/TR13 from Microsemi is a 6.0 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 1N5340CE3/TR13 datasheet, 1N5340CE3/TR13 pinout, 1N5340CE3/TR13 application, or 1N5340CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±2%), maximum surge current (12.7 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 shunt regulator, maintaining a stable 6.0 V reverse breakdown voltage under controlled current conditions. Its low dynamic impedance (1.0 Ω) and tight ±2% tolerance ensure minimal voltage drift across operating current (10%–50% of IZM) and temperature (–65°C to +150°C).
The 1N5340CE3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band polarity marking and is rated for 5.0 W steady-state dissipation at 25°C lead temperature. It withstands 8.3 ms half-sine surge currents up to 12.7 A and exhibits <0.19 V voltage regulation (ΔVZ) between 10% and 50% of maximum Zener current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±2% - precise reference for feedback networks requiring tight DC accuracy |
| Test Current (IZT) | 200 mA - defines nominal operating point where VZ and ZZ are specified |
| Dynamic Impedance (ZZ) | 1.0 Ω - ensures minimal output voltage variation under load transients |
| Max Regulator Current (IZM) | 790 mA - maximum continuous DC current at 25°C lead temperature with adequate heat sinking |
| Surge Current (IZSM) | 12.7 A - peak non-repetitive 8.3 ms half-sine capability for transient suppression |
| Voltage Regulation (ΔVZ) | 0.19 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
| Thermal Resistance (RθJL) | 25 °C/W - junction-to-lead value enables thermal design with 3/8″ (10 mm) lead length from body |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case per JEDEC DO-204AL, void-free UL94V-0 epoxy body, cathode indicated by colored band. Leads feature RoHS-compliant annealed matte-tin plating solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340BTR | ±5% tolerance (B suffix), same 6.0 V nominal, identical T-18 package and IZM | Acceptable where tighter regulation not required; lower cost for non-critical biasing | Select 1N5340BTR when ±5% VZ meets system accuracy budget and RoHS compliance is not mandatory |
| MMSZ5234BT1G | Surface-mount SOD-123 package, 6.2 V nominal, ±5%, 500 mW rating | Not suitable for 5 W power dissipation; limited to low-current references and portable electronics | Choose MMSZ5234BT1G only for space-constrained PCBs with ≤100 mA regulation current and no surge exposure |
Compared with 1N5340BTR and MMSZ5234BT1G, the 1N5340CE3/TR13 uniquely combines ±2% tolerance, 5 W power handling, axial-leaded mechanical robustness, and RoHS compliance-making it the sole option for high-reliability, high-power, precision-regulated industrial power supplies.

FAQ
What is the Zener voltage tolerance of the 1N5340CE3/TR13?
The 1N5340CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual breakdown voltage falls within 5.88 V to 6.12 V at 200 mA test current and 25°C lead temperature, enabling high-accuracy regulation without external trimming circuits.
Does the 1N5340CE3/TR13 require dry packing before reflow soldering?
No, the 1N5340CE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it is not hygroscopic and does not require dry packing or baking prior to reflow soldering. Its void-free epoxy encapsulation ensures compatibility with standard 260°C/10 s solder profiles.
What is the maximum continuous Zener current for the 1N5340CE3/TR13?
The maximum continuous Zener current (IZM) for the 1N5340CE3/TR13 is 790 mA when operated at 25°C lead temperature with adequate heat sinking (3/8″ lead length). At ambient temperature on FR4, derated power limits this to approximately 1.47 W, corresponding to ~245 mA.
How is polarity marked on the 1N5340CE3/TR13?
The 1N5340CE3/TR13 uses a cathode band marking on the body to indicate polarity. The banded end is the cathode and must be held at a higher potential than the anode during Zener regulation. Forward voltage is specified at 1.2 V maximum at 1.0 A, confirming standard silicon diode behavior.
Is the 1N5340CE3/TR13 suitable for surge protection applications?
Yes, the 1N5340CE3/TR13 is rated for a non-repetitive peak surge current (IZSM) of 12.7 A for an 8.3 ms half-sine waveform. This makes it suitable for clamping transient overvoltages in industrial power rails, motor drive snubbers, and telecom line protection-provided average power remains within 5 W limits.
