Product details
Overview
1N5367BRLG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 43 V, ±5% tolerance, 30 Ω maximum zener impedance at 20 mA test current, and 0.7 mA maximum leakage current at 32.7 V. It provides precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation for industrial power converters.
For engineers reviewing the 1N5367BRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 43 V nominal zener voltage, 5 W steady-state power rating, 30 Ω dynamic impedance, 190 mA maximum DC zener current, and Pb-free Surmetic 40 plastic package with cathode band polarity marking.
Technical Context
This device operates as a silicon-oxide passivated junction Zener regulator, optimized for stable reverse-biased breakdown behavior under DC and pulsed conditions. Its thermal design supports junction-to-lead resistance of 25 °C/W at 25 °C ambient with 3/8″ lead length, enabling reliable operation up to +200 °C storage and +150 °C continuous DC operation.
The 1N5367BRLG delivers tight voltage regulation with temperature coefficient characteristics typical of 43 V Zeners (≈+0.085 %/°C), and withstands non-repetitive surge currents up to 190 A at 8.3 ms pulse width per Figure 5 - critical for transient suppression in unregulated input stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B | Same electrical specs but SnPb lead finish; not RoHS-compliant | Acceptable only in legacy non-RoHS production environments | Select 1N5367BRLG for new designs requiring Pb-free compliance and ESD robustness |
| BZX85C43 | 1.3 W rating, 41–45 V range, 100 Ω ZZT; smaller DO-41 package | Suitable for low-power signal-level clamping, not 5 W power regulation | Choose BZX85C43 only when power dissipation <1.3 W and board space is constrained |
Compared with 1N5367B (SnPb) and BZX85C43 (1.3 W), the 1N5367BRLG uniquely combines 5 W power handling, ±5% tolerance, Pb-free compliance, and 30 Ω impedance - making it the only drop-in solution for industrial 43 V shunt regulation where thermal margin and regulatory compliance are mandatory.

FAQ
What is the nominal zener voltage and tolerance of the 1N5367BRLG?
The 1N5367BRLG has a nominal zener voltage of 43 V with a guaranteed tolerance of ±5%, corresponding to a minimum of 40.85 V and maximum of 45.15 V at 20 mA test current (IZT). This tight tolerance is specified per JEDEC standards and validated across production lots, ensuring consistent regulation performance in feedback and clamp applications without post-assembly calibration.
How much power can the 1N5367BRLG dissipate continuously?
The 1N5367BRLG is rated for 5 W steady-state power dissipation at lead temperature (TL) of 25 °C with 3/8″ lead length. Derating is required above 25 °C at 40 mW/°C, reducing usable power to approximately 3.5 W at 65 °C lead temperature. This rating assumes proper PCB copper pour or heatsinking via leads - critical for maintaining junction temperature below 150 °C under DC load.
What is the maximum zener impedance of the 1N5367BRLG and why does it matter?
The 1N5367BRLG has a maximum zener impedance (ZZT) of 30 Ω at IZT = 20 mA. This low dynamic impedance ensures minimal output voltage variation under changing load current - essential for maintaining regulation accuracy in power supply feedback paths. For example, a 10 mA load step induces only 300 mV deviation, directly impacting system stability and ripple rejection in closed-loop designs.
Does the 1N5367BRLG have surge current capability, and what is its rating?
Yes, the 1N5367BRLG supports a non-repetitive peak surge current of 190 A at 8.3 ms pulse width, as confirmed in Figure 5 of the onsemi datasheet. This rating enables the 1N5367BRLG to absorb transient energy from lightning-induced surges or inductive switching spikes without parametric shift or catastrophic failure - a key requirement for front-end protection in industrial AC-DC converters.
Is the 1N5367BRLG RoHS-compliant and what does the 'G' suffix indicate?
Yes, the 1N5367BRLG is RoHS-compliant and Pb-free. The 'G' suffix explicitly denotes a Pb-free package per onsemi's packaging nomenclature, verified in the Ordering Information section and Mechanical Characteristics table. This ensures compatibility with modern lead-free reflow processes and meets global environmental compliance mandates for commercial and industrial end equipment.
