Product details
Overview
1N5341E3/TR13 from Microsemi is a 5.1 V, ±5% 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 240 mA maximum Zener current (IZM), exhibits 1.5 Ω dynamic impedance (ZZ) at 240 mA test current, and operates across –65°C to +150°C.
For engineers reviewing the 1N5341E3/TR13 datasheet, 1N5341E3/TR13 pinout, 1N5341E3/TR13 application, or 1N5341E3/TR13 equivalent, key selection criteria include its 5.1 V nominal Zener voltage, 5 W steady-state power rating at 25°C lead temperature, low 1.5 Ω dynamic impedance, tight ±5% tolerance (B-suffix equivalent), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias operation where the banded end is held positive relative to the anode. Its regulation performance is specified at TL = 25°C with 40 ms DC current application, and voltage regulation (ΔVZ) is defined as the difference between measurements at 10% and 50% of IZM.
The 1N5341E3/TR13 achieves thermal resistance of 25°C/W junction-to-lead (at 10 mm lead length) and 85°C/W junction-to-ambient on FR4 PCB - enabling stable operation up to 14.4 A surge current (8.3 ms half-sine) and 12.4 mA maximum regulator current under B-suffix conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.1 V ±5% - precise reference point for feedback and clamping circuits |
| Test Current (IZT) | 240 mA - operating point at which VZ and ZZ are guaranteed |
| Dynamic Impedance (ZZ) | 1.5 Ω - low AC resistance ensures minimal voltage shift under load transients |
| Max Regulator Current (IZM) | 930 mA - maximum continuous DC current before thermal derating applies |
| Power Dissipation (Pd) | 5.0 W at TL < 25°C - requires adequate heat sinking beyond 25°C lead temp |
| Reverse Leakage (IR) | 1.0 µA max at VR = 3.9 V - ensures low standby power loss in high-impedance bias networks |
| Surge Current (IZSM) | 14.4 A peak (8.3 ms half-sine) - withstands transient overvoltage events without failure |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case per JEDEC DO-204AL; void-free UL94V-0 epoxy body; 0.7 g weight; cathode indicated by band; leads plated with RoHS-compliant matte tin per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; referenced ground node in reverse-bias regulation | Connected to system ground or lower-potential rail when used as shunt regulator |
| Cathode | Current exit terminal in forward bias; regulated output node in reverse-bias operation | Banded end - must be held at higher potential than anode to maintain Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures standardized mechanical dimensions, marking, and reliability testing across suppliers |
| 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) | Eliminates need for special ESD handling during board assembly and test |
| RoHS-compliant (e3 suffix) | Meets EU Directive 2011/65/EU - tin-lead-free termination compatible with lead-free reflow |
| Tape-and-reel packaging (TR13 suffix) | Enables automated pick-and-place assembly with EIA-296 standard carrier tape |

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 5.1 V, ±5%, 5 W rating but with SnPb plating and no e3/TR13 designation | Not RoHS-compliant; requires leaded solder process; supplied in bulk or ammo pack, not tape-and-reel | Select 1N5341B only for legacy leaded assembly or non-RoHS programs |
| MMSZ5231B-TP | Surface-mount SOD-123 package; 5.1 V ±5%; 500 mW power rating; 17 Ω ZZ at 20 mA | Limited to low-power bias/reference use; unsuitable for >100 mA regulation or surge protection | Choose MMSZ5231B-TP only for space-constrained PCBs where 500 mW dissipation suffices |
Compared with 1N5341B and MMSZ5231B-TP, the 1N5341E3/TR13 uniquely combines RoHS compliance, tape-and-reel automation support, 5 W power handling, and axial-leaded through-hole mounting - making it optimal for industrial power supplies requiring field-replaceability and high-energy transient immunity.

FAQ
What is the Zener voltage tolerance of the 1N5341E3/TR13?
The 1N5341E3/TR13 has a Zener voltage tolerance of ±5%, confirmed by its "B"-equivalent suffix in the 1N53xxB family and documented in the Electrical Characteristics table. This tolerance applies at 25°C lead temperature with 240 mA test current, and ensures predictable regulation behavior in feedback and clamp circuits without requiring post-manufacturing calibration.
Does the 1N5341E3/TR13 require dry packing before PCB assembly?
No, the 1N5341E3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it does not absorb significant humidity during storage and requires no dry pack or baking prior to reflow soldering. This simplifies logistics and eliminates yield risk from moisture-induced popcorning during lead-free reflow profiles.
What is the maximum continuous current the 1N5341E3/TR13 can handle?
The 1N5341E3/TR13 supports a maximum continuous Zener current (IZM) of 930 mA when adequately heat sunk at TL < 25°C. At higher lead temperatures, power must be derated linearly per Figure 1 - for example, at TL = 75°C, maximum dissipation drops to 3.75 W, limiting IZM to approximately 730 mA at 5.1 V.
Can the 1N5341E3/TR13 be used in surface-mount designs?
No, the 1N5341E3/TR13 uses axial-leaded T-18 packaging and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5341B (DO-214AA) and SMBG5341B (DO-214AB), both rated for 5 W and sharing identical electrical specs - but these require separate footprint and reflow validation.
What does the "TR13" suffix indicate in 1N5341E3/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels containing 1,000 units. This format enables automated pick-and-place placement and supports high-volume manufacturing; the base part 1N5341E3 retains all electrical and thermal specifications of the bulk version.
