Product details
Overview
1N5340E3/TR13 from Microsemi is a 6.0 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for 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 1N5340E3/TR13 datasheet, 1N5340E3/TR13 pinout, 1N5340E3/TR13 application, or 1N5340E3/TR13 equivalent, key selection criteria include its 6.0 V nominal Zener voltage, 5 W steady-state power rating at 25°C lead temperature, ±5% tolerance (B-suffix compatible), low 1.0 Ω dynamic impedance at IZT, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown. Its regulation performance is defined by Zener voltage (VZ = 6.0 V @ 200 mA), dynamic impedance (ZZ ≤ 1.0 Ω), and voltage regulation (ΔVZ ≤ 0.19 V) measured between 10% and 50% of IZM.
Thermal design relies on junction-to-lead thermal resistance of 25°C/W at 3/8" lead length, enabling 5 W dissipation with adequate heatsinking. It exhibits low reverse leakage (≤1.0 µA @ 4.9 V) and withstands 8.3 ms non-repetitive surge currents up to 12.7 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±5% at 200 mA - defines precise regulation point for feedback or clamping |
| Power Dissipation (PD) | 5.0 W at TL = 25°C - supports high-current regulation without forced cooling |
| Dynamic Impedance (ZZ) | ≤1.0 Ω at IZT = 200 mA - ensures minimal output voltage variation under load changes |
| Max Reverse Current (IR) | ≤1.0 µA at VR = 4.9 V - guarantees low standby power loss in sensing/reference paths |
| Surge Current (IZSM) | 12.7 A (8.3 ms half-sine) - provides robust transient overvoltage suppression capability |
| Operating Temperature | –65°C to +150°C - suitable for industrial, automotive, and aerospace environments |
| Thermal Resistance (RθJL) | 25°C/W junction-to-lead - enables direct thermal coupling to chassis or heatsink via leads |
Pinout & Package
Package: Axial-leaded T-18 plastic case (Void-free transfer-molded thermosetting epoxy, UL94V-0 rated). Cathode indicated by band; device operated with banded end positive relative to opposite end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-biased cathode connection point | Connected to circuit ground or lower-potential node in shunt regulator configuration |
| Cathode | Zener breakdown terminal | Connected to regulated voltage node; band-marked lead carries controlled reference potential |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener series | Ensures standardized mechanical dimensions and electrical behavior across global supply chain |
| RoHS-compliant e3 suffix | Meets EU Directive 2011/65/EU with annealed matte-tin plating, no lead or hazardous substances |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling and eliminates bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Withstands electrostatic discharge without parameter shift or failure - reduces handling controls |
| High surge current rating | 12.7 A peak (8.3 ms) enables single-device transient suppression without external TVS stacking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Same 6.0 V ±5%, identical electrical specs, but leaded SnPb plating (non-RoHS) | Not suitable for RoHS-compliant production; requires exemption documentation | Select 1N5340E3/TR13 for new designs requiring lead-free compliance and tape-and-reel packaging. |
| MMBZ5234B | Surface-mount SOT-23 package, same 6.0 V ±5%, but lower 0.5 W power rating and higher ZZ (7 Ω) | Only viable for low-power biasing or signal-level clamping; cannot replace 5 W dissipation requirement | Choose MMBZ5234B only when board space constraints prohibit axial-leaded devices and power demand is <100 mW. |
Compared with 1N5340B and MMBZ5234B, the 1N5340E3/TR13 uniquely combines RoHS compliance, 5 W power handling, 1.0 Ω dynamic impedance, and tape-and-reel delivery-making it the sole option for high-reliability, high-power, lead-free industrial voltage regulation.

FAQ
What is the Zener voltage tolerance of the 1N5340E3/TR13?
The 1N5340E3/TR13 has a nominal Zener voltage of 6.0 V with a tolerance of ±5%, as indicated by the "B"-compatible "E3" suffix per Microsemi's specification sheet. This tolerance is verified at 200 mA test current and 25°C lead temperature, and applies across the full operating temperature range of –65°C to +150°C without derating.
Does the 1N5340E3/TR13 require dry packing before PCB assembly?
No, the 1N5340E3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity Level 1 classification, meaning it can be stored and assembled without baking or humidity-controlled packaging. This simplifies manufacturing logistics and eliminates pre-reflow bake steps.
What is the maximum surge current rating for the 1N5340E3/TR13?
The 1N5340E3/TR13 is rated for a maximum non-repetitive surge current (IZSM) of 12.7 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating is confirmed in Microsemi's official datasheet and enables use in transient overvoltage suppression without additional series limiting components.
How is polarity marked on the 1N5340E3/TR13?
The 1N5340E3/TR13 uses a cathode band marking: the banded end is the cathode and must be held at a higher potential than the anode to operate in Zener breakdown. Polarity is unambiguous and consistent with JEDEC standard T-18 axial-leaded diode conventions.
Is the 1N5340E3/TR13 suitable for surface-mount assembly?
No, the 1N5340E3/TR13 is an axial-leaded through-hole device in T-18 package and is not designed for surface-mount reflow. For SMT equivalents, Microsemi offers the SMBJ5340B or SMBG5340B - both share the same 6.0 V ±5% specification but use DO-214AA/DO-214AB packages.
