Product details
Overview
1N5340BE3/TR13 from Microsemi is a 6.0 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode with 200 mA test current, 1.0 Ω maximum dynamic impedance at 200 mA, and 790 mA maximum Zener current when adequately heat-sunk; used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N5340BE3/TR13 datasheet, 1N5340BE3/TR13 pinout, 1N5340BE3/TR13 application, or 1N5340BE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (12.7 A), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a reverse-biased voltage reference with stable regulation across 10%–50% of IZM (790 mA), exhibiting ≤0.19 V voltage regulation (ΔVZ) and ≤1.0 Ω dynamic impedance (ZZ) at 200 mA. Its low thermal resistance enables high-current operation with minimal derating when mounted with 3/8″ lead length from body.
The 1N5340BE3/TR13 features a void-free UL94V-0 epoxy case, cathode band polarity marking, and moisture sensitivity level 1 per J-STD-020B-eliminating dry-pack requirements. It withstands 8.3 ms half-sine surge currents up to 12.7 A and maintains <1.0 μA reverse leakage at 4.9 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.0 V ±5% - precise regulation point for feedback sensing in 5–12 V power rails |
| Test Current (IZT) | 200 mA - operating point where VZ and ZZ are specified; defines stable bias condition |
| Dynamic Impedance (ZZ) | 1.0 Ω max at 200 mA - ensures minimal output voltage shift under load transients |
| Max Zener Current (IZM) | 790 mA - maximum continuous DC current with adequate heat sinking (TL ≤ 25°C) |
| Thermal Resistance | 25 °C/W junction-to-lead - enables 5 W dissipation with only 125°C rise above lead temperature |
| Surge Current (IZSM) | 12.7 A peak (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
| Voltage Regulation (ΔVZ) | 0.19 V max - difference between VZ measured at 79 mA and 395 mA, indicating tight regulation linearity |
Pinout & Package
Package: Axial-leaded T-18 plastic case (JEDEC DO-204AL), void-free UL94V-0 epoxy, cathode indicated by color band; leads plated with RoHS-compliant matte tin per MIL-STD-750 Method 2026.

| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated rail or error amplifier input; must be held positive relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance (B suffix) | Enables accurate setpoint control in closed-loop regulators without post-calibration |
| RoHS-compliant e3 suffix | Meets global environmental compliance with matte-tin plating and lead-free assembly compatibility |
| Level 1 moisture sensitivity | Eliminates baking/dry-pack requirements-reduces manufacturing handling cost and risk |

| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Withstands handling without special ESD controls-reduces production line safeguards |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Regulates output voltage in isolated flyback or forward converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener reference providing stable 6.0 V threshold to TL431-like shunt regulator or error amplifier input. Use Value: Maintains ±1% output accuracy over line/load/temperature with 0.19 V ΔVZ and low ZZ ensuring minimal feedback error. | Use Scenario: Clamps transient surges on 5–12 V DC rails caused by inductive switching or ESD events. IC Role / Device Role / Timing Role: Fast-acting shunt clamp absorbing energy during overvoltage excursions up to 12.7 A peak. Use Value: Prevents downstream IC damage by limiting rail voltage to ≤6.3 V (6.0 V + 5%) with no response delay. |
| Programmable Voltage Reference | Industrial Sensor Excitation |
Use Scenario: Provides stable excitation voltage for precision resistive sensors (e.g., RTDs, strain gauges) in 4–20 mA transmitters. IC Role / Device Role / Timing Role: Low-drift, low-noise reference source replacing higher-cost bandgap ICs in cost-sensitive analog front-ends. Use Value: Delivers 6.0 V ±5% with <1.0 μA leakage at 4.9 V-minimizing sensor bridge current error and self-heating. | Use Scenario: Supplies regulated bias to analog signal conditioning stages in PLC I/O modules operating from unregulated 24 V DC bus. IC Role / Device Role / Timing Role: Local point-of-load regulator stabilizing op-amp supply rails against bus ripple and dropouts. Use Value: Ensures op-amp PSRR > 80 dB by rejecting >99% of 120 Hz ripple with 1.0 Ω dynamic impedance and 5 W headroom. |
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 (non-e3, non-TR) | Same electrical specs but SnPb lead finish and bulk packaging; lacks RoHS compliance and tape-and-reel convenience | Not suitable for lead-free reflow or automated pick-and-place; requires manual loading or tube-to-tape conversion | Select only for legacy SnPb assembly or non-RoHS environments where tape-and-reel is unnecessary |
| MMSZ5234B-TP (Micro Commercial Co.) | Surface-mount SOD-123 package; same 6.0 V ±5%, but lower 500 mW rating and 10 Ω ZZ at 20 mA | Cannot replace 1N5340BE3/TR13 in high-power (>1 W) or high-surge scenarios; limited to low-current references | Choose only for space-constrained PCBs where power dissipation stays below 0.5 W and surge immunity is secondary |
Compared with 1N5340B and MMSZ5234B-TP, the 1N5340BE3/TR13 uniquely combines 5 W power handling, axial-leaded mechanical robustness, RoHS compliance, and tape-and-reel delivery-making it optimal for industrial power supplies requiring field-replaceable, high-surge-tolerant Zeners.

FAQ
What is the Zener voltage tolerance of the 1N5340BE3/TR13?
The 1N5340BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its nominal 6.0 V regulation point falls within 5.7 V to 6.3 V at 200 mA test current and 25 °C lead temperature. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296 standard.
Can the 1N5340BE3/TR13 be used in surface-mount designs?
No-the 1N5340BE3/TR13 uses an axial-leaded T-18 (DO-204AL) package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5340B series in SMB package, while third-party alternatives like MMSZ5234B-TP exist-but none match the 5 W power rating or 12.7 A surge capability of the 1N5340BE3/TR13.
What is the maximum continuous Zener current for the 1N5340BE3/TR13?
The maximum continuous Zener current (IZM) for the 1N5340BE3/TR13 is 790 mA when operated with lead temperature (TL) maintained at or below 25 °C-typically achieved using ≥3/8″ (10 mm) lead length from the epoxy body. At ambient temperature (TA = 25 °C) on FR4 board, steady-state power drops to 1.47 W, limiting IZM to approximately 245 mA.
Does the 1N5340BE3/TR13 require dry packing before reflow soldering?
No-the 1N5340BE3/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. Its void-free thermosetting epoxy body inherently resists moisture absorption, simplifying handling and reducing manufacturing risk.
How does the 1N5340BE3/TR13 perform under surge conditions?
The 1N5340BE3/TR13 is rated for 12.7 A peak non-recurrent surge current (IZSM) in an 8.3 ms half-sine waveform-validated per JEDEC standards. This allows it to safely clamp repetitive transients in industrial power rails without degradation, provided average power remains within 5 W derating limits and thermal paths prevent junction overheating.
