Product details
Overview
1N5367BE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 43 V, ±5% tolerance (B suffix), 30 mA test current, 20 Ω dynamic impedance at IZT, and maximum reverse current of 0.5 μA at 32.7 V. It operates from –65°C to +150°C and is used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N5367BE3/TR13 datasheet, 1N5367BE3/TR13 pinout, 1N5367BE3/TR13 application, or 1N5367BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (190 A), voltage regulation (ΔVZ = 2.8 V), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage regulator operating in reverse breakdown. Its Zener voltage is specified at 43 V ±5% under 30 mA DC test current at TL = 25°C, with dynamic impedance measured at 1 kHz AC superimposed on DC bias.
Thermal performance is defined by junction-to-lead resistance of 25 °C/W at 3/8″ lead length, enabling stable regulation up to 5 W dissipation with adequate heat sinking. The cathode band indicates polarity, requiring the banded end to be held positive relative to the anode during operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 43 V ±5% - precise regulation point for feedback networks and reference circuits |
| Test Current (IZT) | 30 mA - standardized bias condition for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 20 Ω at IZT - low AC resistance ensures minimal output voltage variation under load changes |
| Max Reverse Current (IR) | 0.5 μA at 32.7 V - confirms sharp knee and low leakage below regulation threshold |
| Max Regulator Current (IZM) | 190 mA - maximum continuous DC current before exceeding 5 W power limit at 25°C lead temperature |
| Voltage Regulation (ΔVZ) | 2.8 V - difference between VZ at 10% and 50% of IZM, indicating regulation stability across operating range |
| Surge Current (IZSM) | 190 A (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables high-power operation when leads are thermally anchored to heatsink or chassis |
Pinout & Package
Package: Axial-leaded T-18 plastic case (Void-free transfer-molded thermosetting epoxy, UL94V-0 rated); cathode identified by color band; RoHS-compliant annealed matte-tin plating; weight 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires this terminal to be at lower potential than cathode |
| Cathode | Regulated output node | Banded end; held at stable 43 V above anode when reverse current ≥30 mA; serves as voltage reference or clamp point |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures industry-standard mechanical dimensions, marking, and reliability testing compliance |
| ±5% voltage tolerance (B suffix) | Meets mid-tier precision requirements without premium cost of ±1% or ±2% variants |
| RoHS-compliant e3 suffix | Lead-free matte-tin plating meets environmental directives without compromising solderability per MIL-STD-750 |
| Moisture sensitivity Level 1 | No dry pack required - simplifies handling, storage, and assembly logistics |
| High surge current capability | 190 A non-recurrent half-sine rating enables robust transient suppression in industrial power rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B (non-e3) | Same electrical specs but SnPb plating; not RoHS-compliant | Restricted to legacy military/aerospace builds requiring tin-lead solder compatibility | Select only if SnPb assembly process is mandated and RoHS exemption applies |
| MMSZ5267ET1G | Surface-mount SOD-123 package; 43 V ±5%; 500 mW rating; 100 Ω ZZ | Limited to low-power signal-level regulation; unsuitable for >100 mA continuous use | Choose for space-constrained PCBs where 5 W dissipation is unnecessary |
Compared with 1N5367BE3/TR13, the 1N5367B offers identical regulation performance but lacks RoHS compliance, while MMSZ5267ET1G trades power handling and thermal robustness for miniaturization-making it viable only in low-current, surface-mount designs.

FAQ
What is the Zener voltage tolerance for 1N5367BE3/TR13?
The 1N5367BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its regulated voltage falls within 40.85 V to 45.15 V at 30 mA test current and 25°C lead temperature, per Microsemi's published electrical characteristics table.
Does 1N5367BE3/TR13 require dry packing before PCB assembly?
No, the 1N5367BE3/TR13 has moisture sensitivity level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry packing or baking prior to reflow soldering. Its void-free epoxy encapsulation and Level 1 rating allow indefinite floor life under standard ambient conditions.
What is the maximum continuous current for 1N5367BE3/TR13 at 25°C?
The maximum continuous Zener current for 1N5367BE3/TR13 is 190 mA at TL = 25°C (3/8″ lead length), derived from its 5 W power rating and upper-limit Zener voltage of 45.15 V (43 V × 1.05). Exceeding this current risks thermal overstress unless additional heatsinking is applied.
Can 1N5367BE3/TR13 be used in surface-mount designs?
No, the 1N5367BE3/TR13 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5367B or SMBG5367B in DO-214AA/DO-214AB packages-both share identical electrical specs but differ mechanically.
What is the forward voltage specification for 1N5367BE3/TR13?
The forward voltage for 1N5367BE3/TR13 is specified as ≤1.2 V at 1.0 A forward current. This parameter applies only during forward conduction (anode positive relative to cathode) and is relevant for polarity protection or rectifier backup roles-not for normal Zener regulation operation.
