Product details
Overview
1N5341BE3/TR13 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 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 1N5341BE3/TR13 datasheet, 1N5341BE3/TR13 pinout, 1N5341BE3/TR13 application, or 1N5341BE3/TR13 equivalent, this part supports stable DC reference generation, low-noise shunt regulation, and transient-suppression-coupled clamping where precise 6.2 V stabilization under variable load and temperature is required.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a nominal Zener voltage of 6.2 V measured at 200 mA test current (IZT). Its thermal resistance is 25 °C/W junction-to-lead (3/8" lead length), enabling reliable 5 W dissipation with minimal heatsinking.
It exhibits low dynamic impedance (1.0 Ω) and tight voltage regulation (ΔVZ = 0.10 V between 10% and 50% IZM), ensuring minimal output drift across operating current range. Reverse leakage is limited to ≤1.0 μA at 3.0 V VR, supporting high-impedance bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% - Stable reference point for precision shunt regulation at nominal 200 mA bias. |
| Power Dissipation (Pd) | 5.0 W at TL = 25°C - Supports robust continuous operation with standard axial-lead mounting and modest heatsinking. |
| Dynamic Impedance (ZZ) | 1.0 Ω @ IZT = 200 mA - Ensures <0.2 V output variation across 100–500 mA load current changes. |
| Max Zener Current (IZM) | 765 mA - Enables high-current clamping without thermal runaway when adequately heat-sunk. |
| Reverse Leakage (IR) | ≤1.0 μA @ VR = 3.0 V - Maintains low quiescent current in high-impedance reference divider networks. |
| Voltage Regulation (ΔVZ) | 0.10 V - Difference between VZ at 10% and 50% of IZM; quantifies line regulation performance. |
| Operating Temperature | –65°C to +150°C - Validated for industrial and automotive under-hood environments without derating. |
Pinout & Package
Package: Axial-leaded T-18 plastic case (JEDEC DO-201AD), void-free UL94V-0 epoxy body, matte-tin plated leads, cathode indicated by band. Weight: 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or lower-potential rail; defines common return path for Zener current. |
| Cathode (banded end) | Regulated output node | Provides stabilized 6.2 V relative to anode; must be biased positive w.r.t. anode to enter breakdown. |
Key Features
| Feature | Design Value |
|---|---|

| Moisture Sensitivity Level 1 | No dry pack required per IPC/JEDEC J-STD-020B - simplifies SMT reflow and storage logistics. |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - withstands human-body-model discharges without parameter shift. |
| High surge current rating | 200 A peak (8.3 ms half-sine) - enables robust transient suppression in power rail protection circuits. |
| Low thermal resistance | 25 °C/W junction-to-lead - allows full 5 W dissipation with only 3/8" lead length as heatsink. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | No e3 RoHS suffix; SnPb lead finish; otherwise identical electrical specs and package. | Not compliant with EU RoHS Directive; restricted for new designs targeting export markets. | Select 1N5341B only for legacy repair or non-RoHS-compliant military/aerospace programs requiring SnPb solder compatibility. |
| MMBZ5234BS | Surface-mount SOT-23 package; 6.2 V ±5%; 200 mW Pd; 100 mA IZM - not a direct power replacement. | Intended for low-power signal-level clamping, not 5 W regulation; requires PCB redesign and thermal analysis. | Choose MMBZ5234BS only for space-constrained, low-current bias networks where 5 W capability is unnecessary. |
Compared with 1N5341B and MMBZ5234BS, the 1N5341BE3/TR13 uniquely combines RoHS compliance, 5 W power handling, axial-leaded through-hole mountability, and industrial temperature range - making it the sole option for high-reliability, medium-power shunt regulation without layout change.

FAQ
What is the Zener voltage tolerance of the 1N5341BE3/TR13?
The 1N5341BE3/TR13 has a Zener voltage tolerance of ±5%, as indicated by the "B" suffix in its part number. This means its nominal 6.2 V Zener voltage is guaranteed between 5.89 V and 6.51 V at 200 mA test current and 25°C lead temperature. The e3 suffix confirms RoHS compliance but does not affect voltage tolerance.
Can the 1N5341BE3/TR13 be used in surface-mount designs?
No - the 1N5341BE3/TR13 uses an axial-leaded T-18 (DO-201AD) package and is intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the SMBJ5341B or SMBG5341B in SMB/SMBG packages, which share identical electrical specs but require different PCB layout and reflow profiles.
What is the maximum surge current rating for the 1N5341BE3/TR13?
The 1N5341BE3/TR13 is rated for a maximum non-recurrent surge current (IZSM) of 200 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating assumes proper lead mounting and adequate board copper area; exceeding it risks irreversible junction damage even if average power remains within 5 W limits.
How does thermal resistance affect the 1N5341BE3/TR13's power handling?
The 1N5341BE3/TR13 has a junction-to-lead thermal resistance of 25 °C/W when mounted with 3/8" (10 mm) lead length from the body. At 25°C ambient, this allows full 5 W dissipation; above 25°C, power must be linearly derated - e.g., at 75°C lead temperature, max power drops to 3 W to maintain safe junction temperature.
Is the 1N5341BE3/TR13 suitable for precision voltage reference applications?
Yes - the 1N5341BE3/TR13 provides 0.10 V voltage regulation (ΔVZ) between 10% and 50% of IZM and 1.0 Ω dynamic impedance, supporting stable reference generation. However, for sub-0.05% accuracy, external trimming or temperature compensation is recommended, as its ±5% initial tolerance and 0.01%/°C tempco limit ultimate precision.
