Product details
Overview
1N5341BE3/TR12 from Microsemi is a 6.2 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply reference and overvoltage protection circuits. It delivers stable regulation at 200 mA test current with 1.0 Ω dynamic impedance, 0.10 V voltage regulation (ΔVZ), and operates across –65°C to +150°C.
For engineers reviewing the 1N5341BE3/TR12 datasheet, 1N5341BE3/TR12 pinout, 1N5341BE3/TR12 application, or 1N5341BE3/TR12 equivalent, this part serves as a high-reliability, RoHS-compliant, tape-and-reel packaged Zener for industrial power rails, analog reference design, and transient-suppressed bias networks requiring precise 6.2 V clamping.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown mode. Its 6.2 V nominal Zener voltage is specified at 200 mA (IZT), with tight ±5% tolerance (B suffix) and low 1.0 Ω dynamic impedance (ZZ) ensuring minimal output variation under load changes.
Thermal performance is defined by 25 °C/W junction-to-lead resistance at 10 mm lead length, enabling 5 W dissipation at TL ≤ 25°C. It meets MIL-STD-750 ESD immunity (Method 1020) and withstands 12.4 A non-recurrent surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% - precise DC reference point for feedback loops and clamp thresholds |
| Test Current (IZT) | 200 mA - operating point where VZ and ZZ are guaranteed per JEDEC spec |
| Dynamic Impedance (ZZ) | 1.0 Ω - low AC resistance ensures <10 mV output shift per 10 mA load change |
| Max Regulator Current (IZM) | 765 mA - maximum continuous reverse current before thermal runaway at TL = 25°C |
| Voltage Regulation (ΔVZ) | 0.10 V - difference between VZ measured at 10% and 50% of IZM, indicating line regulation stability |
| Surge Current (IZSM) | 12.4 A - peak non-repetitive current handling for transient suppression (8.3 ms half-sine) |
| Forward Voltage (VF) | 1.2 V max @ 1.0 A - defines forward conduction loss in series protection configurations |
Pinout & Package
Package: Axial-leaded T-18 plastic case (JEDEC DO-201AD), RoHS-compliant matte-tin plated leads, cathode indicated by band. Weight: 0.7 g. Moisture sensitivity level: Level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires cathode at higher potential |
| Cathode | Regulated output node | Banded end; supplies stable 6.2 V when reverse-biased above breakdown threshold |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures cross-manufacturer compatibility and standardized test conditions per 1N53xxB spec |
| RoHS-compliant e3 suffix | Lead-free termination meets EU Directive 2011/65/EU without compromising solderability or reliability |
| Tape-and-reel TR12 packaging | Standard EIA-296 compliant reel (1200 pcs/reel) enables automated SMT placement despite axial form factor |
| Level 1 moisture sensitivity | Zero bake requirement prior to assembly - reduces manufacturing overhead and avoids thermal stress |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for special ESD handling during board assembly and field service |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | No e3/RoHS suffix; SnPb plating; same VZ, IZT, ZZ, IZM, ΔVZ, and package | Not suitable for RoHS-compliant production; requires Pb-containing solder process | Select only for legacy repair or non-RoHS programs where SnPb assembly is mandated |
| MMSZ5234B-TP | Surface-mount SOD-123 package; 6.2 V ±5%; 500 mW rating; 10 Ω ZZ; 100 mA IZM | Lower power, smaller footprint; unsuitable for >500 mW continuous dissipation or high-surge scenarios | Choose for space-constrained PCBs where 5 W capability is unnecessary and thermal mass is limited |

FAQ
What is the Zener voltage tolerance of the 1N5341BE3/TR12?
The 1N5341BE3/TR12 has a nominal Zener voltage of 6.2 V with a ±5% tolerance, as indicated by the "B" suffix in its part number. This means the actual breakdown voltage falls between 5.89 V and 6.51 V at 200 mA test current and 25°C lead temperature, per JEDEC-registered specifications.
Can the 1N5341BE3/TR12 be used in surface-mount designs?
The 1N5341BE3/TR12 is an axial-leaded T-18 (DO-201AD) package and is not a surface-mount device. However, it is supplied on EIA-296 tape-and-reel (TR12) for automated insertion equipment. For true SMT implementation, consider the SMBJ5341B or MMSZ5234B-TP as functional alternatives with different power and package constraints.
What is the maximum continuous reverse current for the 1N5341BE3/TR12?
The maximum continuous Zener current (IZM) for the 1N5341BE3/TR12 is 765 mA when operated with lead temperature (TL) maintained at or below 25°C using adequate heat sinking. Derating applies above 25°C per the published power derating curve in the Microsemi datasheet.
Does the 1N5341BE3/TR12 meet RoHS requirements?
Yes - the "e3" suffix explicitly denotes RoHS compliance, confirming lead-free matte-tin plating on the leads and adherence to EU Directive 2011/65/EU. The device contains no restricted substances above threshold limits and requires no dry-pack moisture barrier bag.
How is polarity identified on the 1N5341BE3/TR12?
Polarity is marked by a single color band on the cathode end of the 1N5341BE3/TR12. During operation, the banded (cathode) terminal must be held at a higher potential than the anode to achieve reverse-bias Zener conduction. Forward conduction occurs when anode is positive relative to cathode, with VF ≤ 1.2 V at 1.0 A.
