Product details
Overview
1N5375BRL from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 82 V, ±5% tolerance, 15 Ω maximum zener impedance at 65 mA test current, and 1.8 mA maximum leakage current at 62.2 V. It operates across −65 °C to +200 °C and delivers stable voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N5375BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its 82 V nominal breakdown voltage, 720 mA maximum DC zener current, 180 W surge rating at 8.3 ms, and Pb-free Surmetic 40 plastic package with cathode band polarity marking.
Technical Context
This device uses silicon-oxide passivated junction technology to achieve tight voltage tolerance (±5%), low dynamic impedance, and high ESD robustness (>16 kV HBM). Its thermal design relies on lead-to-ambient conduction, with junction-to-lead thermal resistance of 25 °C/W at 3/8″ lead length.
The 1N5375BRL exhibits a positive temperature coefficient above 6 V, typical for higher-voltage Zeners, and maintains regulation stability under pulsed conditions up to 200 °C with low duty cycle. Its 8.3 ms surge rating supports transient suppression in DC power rails without external clamping components.
Key Specifications

| Power Dissipation (PD) | 5 W at TL = 25 °C - sets maximum continuous power handling in linear regulator or shunt applications |
| Zener Impedance (ZZT) | 15 Ω max @ IZT = 65 mA - ensures minimal output voltage variation under load transients |
| Leakage Current (IR) | 1.8 mA max @ VR = 62.2 V - guarantees low standby power loss in high-impedance bias networks |
| Surge Current (IRM) | 720 A peak @ 8.3 ms - enables single-pulse transient suppression without derating in 48 V–110 V systems |
| Operating Temperature | −65 °C to +200 °C - supports operation in automotive engine compartments and industrial motor drives |
| ESD Rating | Class 3 (>16 kV) HBM - eliminates need for external ESD protection in board-level handling and assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375B | Same electrical specs but in bulk box (1000 units), not tape-and-reel; identical Surmetic 40 package and marking | No difference in circuit function or layout; only packaging format differs | Select 1N5375B for manual prototyping or low-volume hand-soldered builds |
| BZX85C82 | 5 W Zener, 82 V nominal, but 10% tolerance (vs. ±5%), higher ZZT (20 Ω vs. 15 Ω), and TO-204AA metal can package | Lower accuracy and higher impedance reduce regulation stability in precision references; metal can requires different mounting | Choose BZX85C82 only if legacy design compatibility or metal-can EMI shielding is required |
Compared with 1N5375BRL, the 1N5375B offers identical performance in a different packaging format ideal for bench use, while BZX85C82 trades accuracy and impedance for legacy compatibility and EMI shielding-neither is pin-compatible due to differing axial vs. radial lead geometry and case dimensions.

FAQ
What is the nominal zener voltage and tolerance of the 1N5375BRL?
The 1N5375BRL has a nominal zener voltage of 82 V with a guaranteed tolerance of ±5%, meaning its actual breakdown voltage falls between 77.9 V and 86.1 V at 65 mA test current. This tight tolerance ensures predictable regulation behavior in precision reference and feedback applications without requiring post-installation adjustment.
How does the 1N5375BRL handle transient overvoltage events?
The 1N5375BRL supports up to 180 W non-repetitive surge power for 8.3 ms, corresponding to a peak surge current of 720 A at its 82 V rating. This capability allows it to absorb transient energy from inductive switching or lightning-induced surges in DC power systems without degradation, provided pulse repetition is limited per datasheet derating curves.
Is the 1N5375BRL compatible with lead-free soldering processes?
Yes, the 1N5375BRL is Pb-free and qualified for lead-free reflow soldering per JEDEC J-STD-020. Its maximum lead temperature rating is 260 °C for 10 seconds at 1/16 inch from the case, fully supporting standard Pb-free assembly processes used in modern electronics manufacturing.
What is the thermal resistance characteristic of the 1N5375BRL?
The 1N5375BRL has a junction-to-lead thermal resistance (θJL) of 25 °C/W when mounted with 3/8 inch lead length. This value enables direct heat conduction from the die to PCB copper or chassis via the leads, allowing reliable 5 W continuous operation without additional heatsinking in properly designed layouts.
Can the 1N5375BRL be used in automotive under-hood applications?
Yes, the 1N5375BRL is rated for operation from −65 °C to +200 °C, covering the full extended temperature range required for under-hood automotive electronics. Its silicon-oxide passivated junction and Surmetic 40 package provide proven reliability in high-vibration, high-temperature engine compartment environments.
