Product details
Overview
1N5341AE3/TR13 from Microsemi is a 6.2 V, ±10% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply feedback loops, overvoltage protection circuits, and precision reference applications. It delivers 200 mA maximum Zener current (IZM) at 25°C with 1.0 Ω dynamic impedance (ZZ) and operates across –65°C to +150°C.
For engineers reviewing the 1N5341AE3/TR13 datasheet, 1N5341AE3/TR13 pinout, 1N5341AE3/TR13 application, or 1N5341AE3/TR13 equivalent, key selection criteria include its 6.2 V nominal Zener voltage, ±10% tolerance (A suffix), 5 W power rating, 1.0 Ω dynamic impedance at 200 mA test current, and RoHS-compliant matte-tin plating per e3 suffix.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown mode. Its Zener voltage is specified at 200 mA (IZT), with voltage regulation (ΔVZ) of 0.10 V between 10% and 50% of IZM, and dynamic knee impedance (ZZK) of 500 Ω at 1.0 mA.
Thermal design relies on junction-to-lead thermal resistance of 25 °C/W at 10 mm lead length, enabling stable regulation under high-current DC conditions when adequately heat-sunk. Reverse leakage remains ≤1.0 µA up to 4.9 V (VR), confirming tight low-current stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, ±10% tolerance - defines regulated output voltage window (5.58–6.82 V) for feedback or clamping |
| Power Dissipation (Pd) | 5.0 W at TL = 25°C - supports high-current regulation without external heatsink if leads serve as thermal path |
| Test Current (IZT) | 200 mA - operating point where VZ and ZZ are guaranteed; matches typical SMPS feedback current levels |
| Dynamic Impedance (ZZ) | 1.0 Ω max at IZT - ensures minimal output voltage shift under load transients |
| Max Regulator Current (IZM) | 765 mA - maximum continuous DC current before thermal runaway, calculated as Pd/VZmin (5 W / 6.58 V) |
| Reverse Leakage (IR) | ≤1.0 µA at VR = 4.9 V - guarantees low standby power loss in high-impedance bias networks |
| Voltage Regulation (ΔVZ) | 0.10 V - difference between VZ measured at 76.5 mA and 382.5 mA, indicating line regulation fidelity |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), cathode indicated by band; RoHS-compliant matte-tin plated leads solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference/ground node | Connected to circuit ground or lower-potential rail; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener output node | Banded end; supplies regulated voltage to feedback divider or clamp load; polarity critical for proper breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener | Complies with industry-standard 1N53xxB family mechanical and electrical definitions for interchangeability |
| Moisture Sensitivity Level 1 | No dry pack required - simplifies SMT reflow prep and reduces handling overhead for board assembly |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - eliminates need for special ESD handling during manual or automated placement |
| High surge current rating | 200 A peak (8.3 ms half-sine) - withstands transient overvoltage events without degradation |
| Stable regulation over temperature | Operates from –65°C to +150°C - suitable for automotive engine bay or industrial motor drive environments |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Used in the optocoupler feedback network of an isolated 12 V DC-DC converter to regulate output voltage. IC Role / Device Role / Timing Role: Zener reference element setting precise error amplifier threshold; replaces TL431 in cost-sensitive designs. Use Value: 6.2 V nominal voltage aligns with common 5 V logic-level optocoupler input thresholds, enabling direct interface without level-shifting resistors. |
Use Scenario: Placed across a 5 V rail to protect downstream logic ICs from accidental 12 V misconnection. IC Role / Device Role / Timing Role: Shunt clamping device that conducts above 6.82 V (VZmax), diverting fault current away from sensitive loads. Use Value: 5 W power rating sustains 1.2 A fault current for >100 ms, providing robust transient energy absorption without thermal failure. |
| Precision Voltage Reference | Industrial Sensor Excitation |
Use Scenario: Supplies stable excitation to a 350 Ω strain gauge bridge in a load cell signal conditioner. IC Role / Device Role / Timing Role: Low-drift, low-noise DC reference source; buffered via op-amp to drive bridge legs. Use Value: 1.0 Ω dynamic impedance minimizes voltage droop under 10 mA bridge current, maintaining <0.01% measurement accuracy. |
Use Scenario: Provides regulated bias to a 4–20 mA loop-powered pressure transmitter's internal analog front-end. IC Role / Device Role / Timing Role: Primary voltage reference for DAC and current-sense amplifier; operates continuously at 8 mA quiescent current. Use Value: Stable 6.2 V output over –40°C to +85°C enables <±0.5% full-scale error across industrial temperature range without calibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same 6.2 V nominal, but ±5% tolerance (B suffix) vs. ±10% (A suffix); 1.0 Ω ZZ unchanged | Tighter tolerance improves regulation accuracy in precision references but increases cost | Select 1N5341B when output stability better than ±0.3 V is required; otherwise 1N5341AE3/TR13 offers cost advantage |
| MMBZ5234B-TP | Surface-mount SOD-123 package; same 6.2 V, ±5%; 500 mW rating (vs. 5 W); 10 Ω ZZ | Lower power and impedance limit use to low-current biasing, not power regulation or clamping | Choose MMBZ5234B-TP only for space-constrained PCBs with <50 mA load; not a functional replacement for 1N5341AE3/TR13 in power roles |
Compared with 1N5341B and MMBZ5234B-TP, the 1N5341AE3/TR13 uniquely balances high-power capability (5 W), axial-leaded through-hole mounting, and RoHS compliance-making it optimal for legacy industrial power supplies and ruggedized overvoltage protection where thermal mass and mechanical robustness matter.

FAQ
What is the Zener voltage tolerance of the 1N5341AE3/TR13?
The 1N5341AE3/TR13 has a ±10% Zener voltage tolerance, denoted by the "A" suffix in its part number. This means its actual breakdown voltage falls between 5.58 V and 6.82 V at 200 mA test current and 25°C. The e3 suffix confirms RoHS compliance, and TR13 indicates tape-and-reel packaging per EIA-296 standard.
Can the 1N5341AE3/TR13 be used in surface-mount designs?
No-the 1N5341AE3/TR13 is an axial-leaded T-18 package device intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the SMBJ5341B or SMBG5341B in DO-214AA/DO-214AB packages. These share the same 6.2 V rating but differ in thermal performance, surge capability, and footprint compatibility.
What is the maximum steady-state current the 1N5341AE3/TR13 can handle at room temperature?
At 25°C lead temperature (TL), the 1N5341AE3/TR13 supports a maximum Zener current (IZM) of 765 mA, derived from its 5 W power rating divided by the minimum guaranteed Zener voltage (6.2 V × 0.9 = 5.58 V). This assumes adequate heat sinking via 10 mm lead length; derating applies above 25°C.
Does the 1N5341AE3/TR13 meet moisture sensitivity requirements for reflow soldering?
Yes-the 1N5341AE3/TR13 is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30°C/60% RH without dry packing. Its thermosetting epoxy body and matte-tin plating support standard 260°C/10 s solder profiles without popcorn or delamination risk.
How does the 1N5341AE3/TR13 compare to the 1N4735A in terms of power handling?
The 1N5341AE3/TR13 is rated for 5 W continuous dissipation, while the 1N4735A is a 1 W device. Both regulate at ~6.2 V, but the 1N5341AE3/TR13 sustains 5× higher current (765 mA vs. 167 mA) and exhibits lower dynamic impedance (1.0 Ω vs. ~5 Ω), making it suitable for high-current feedback and clamping where thermal margin is critical.
