Product details
Overview
1N5367BRL from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 43 V, ±5% tolerance, maximum zener impedance of 30 Ω at 20 mA test current, and surge rating of 190 A at 8.3 ms. It serves as a precision voltage reference or overvoltage clamp in DC power supply regulation circuits.
For engineers reviewing the 1N5367BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its 43 V nominal regulation voltage, 30 Ω dynamic impedance at IZT = 20 mA, 0.7 mA leakage current at VR = 32.7 V, 5 W steady-state power dissipation, and axial Surmetic 40 package compatibility with through-hole PCB assembly.
Technical Context
This device operates as a silicon-oxide passivated junction Zener regulator, optimized for stable DC voltage reference under varying load and temperature conditions. Its thermal resistance from junction-to-lead is 25 °C/W at TL = 25°C with 3/8″ lead length, enabling reliable heat transfer in compact layouts.
The 1N5367BRL exhibits a positive temperature coefficient above 5 V, with typical TC of +25 mV/°C at 43 V, supporting predictable drift compensation in feedback networks. It meets Class 3 ESD immunity (>16 kV HBM) and withstands non-repetitive 8.3 ms surges up to 190 A without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 40.85–45.15 V (±5% tolerance at IZT = 20 mA; defines regulated output voltage window) |
| Power Dissipation (PD) | 5 W max at TL = 25°C (sets absolute upper limit for continuous DC power handling) |
| Zener Impedance (ZZT) | 30 Ω max at IZT = 20 mA (determines regulation stiffness under load transients) |
| Leakage Current (IR) | 0.7 mA max at VR = 32.7 V (defines minimum off-state current in clamping mode) |
| Surge Current (IRM) | 190 A peak at 8.3 ms (supports transient overvoltage suppression without failure) |
| Junction-to-Lead RθJL | 25 °C/W (enables thermal design using lead as heatsink; derates 40 mW/°C above 25°C) |
| ESD Rating | Class 3 (>16 kV HBM) (ensures robustness during manual handling and board assembly) |
Pinout & Package
Package: Axial-lead Surmetic 40 plastic case (Case 017AA), void-free transfer-molded thermosetting material, cathode indicated by band, RoHS-compliant Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Zener breakdown terminal / Regulation output node | Connected to higher-potential rail; delivers stable 43 V reference when reverse-biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| 5 W Zener regulation | Enables direct replacement of lower-power Zeners in high-current reference paths without external heatsinking |
| ±5% VZ tolerance | Reduces binning requirements and simplifies BOM management across production lots |
| 25 °C/W junction-to-lead thermal resistance | Allows use of PCB copper pour or chassis mounting via leads for passive thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5367B | Same electrical specs but in bulk box (1000 units), not tape-and-reel; identical Surmetic 40 package | No difference in circuit function or layout; only packaging format differs | Select 1N5367B for manual prototyping or low-volume hand-soldered builds |
| MMBZ5263B | Surface-mount SOT-23 package, 43 V nominal, 0.2 W rating, 100 Ω ZZT; no surge rating specified | Not suitable for 5 W power dissipation or surge suppression; limited to low-current bias/reference roles | Choose MMBZ5263B only for space-constrained PCBs where power and surge demands are ≤100 mW |
Compared with 1N5367BRL, the 1N5367B offers identical performance in a different packaging format ideal for low-volume assembly, while MMBZ5263B trades power capability and surge robustness for miniaturization-making it unsuitable as a drop-in replacement in high-energy applications.

FAQ
What is the nominal zener voltage of the 1N5367BRL?
The 1N5367BRL has a nominal zener voltage of 43 V, with a guaranteed range of 40.85 V to 45.15 V at 20 mA test current (IZT), per JEDEC-standard ±5% tolerance. This value is measured under controlled 40 ms pulse conditions at 25°C ambient, and remains stable across its −65°C to +200°C operating temperature range.
How does the 1N5367BRL handle surge conditions?
The 1N5367BRL supports a peak non-repetitive surge current of 190 A at 8.3 ms pulse width, validated per onsemi's Figure 5 data. Its robust silicon-oxide passivated junction and axial Surmetic 40 package enable this performance without parameter shift, making it suitable for ISO 7637-2 compliant automotive load-dump protection and industrial power-line surge suppression.
Is the 1N5367BRL RoHS-compliant and lead-free?
Yes, the 1N5367BRL is a Pb-free device, indicated by the "G" suffix in its ordering code per onsemi documentation. It complies with RoHS Directive 2011/65/EU and uses thermosetting plastic encapsulation with corrosion-resistant, readily solderable leads rated for 260°C for 10 seconds at 1/16 inch from case.
What is the maximum power dissipation of the 1N5367BRL?
The 1N5367BRL has a maximum steady-state power dissipation of 5 W at lead temperature (TL) = 25°C with 3/8 inch lead length. Above 25°C, it derates linearly at 40 mW/°C, reaching zero dissipation at 150°C junction temperature under DC conditions-consistent with its 25 °C/W junction-to-lead thermal resistance.
Can the 1N5367BRL be used as a direct replacement for older 1N5367 versions?
Yes, the 1N5367BRL is functionally and mechanically identical to legacy 1N5367 variants except for Pb-free packaging. Its electrical parameters-including 43 V nominal VZ, 30 Ω ZZT, and 190 A surge rating-are unchanged. No PCB layout or schematic modification is required when upgrading from leaded 1N5367 to 1N5367BRL.
