Product details
Overview
1N5350BRLG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 13 V (±5%), maximum zener impedance of 100 Ω at 2.5 mA test current, 100 A peak surge current capability at 8.3 ms, and ESD rating >16 kV per Human Body Model. It serves as a precision voltage reference or shunt regulator in DC power supply feedback loops, overvoltage protection circuits, and voltage-clamping applications.
For engineers reviewing the 1N5350BRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 13 V nominal regulation voltage, 100 Ω dynamic impedance at IZT = 2.5 mA, 5 W steady-state power dissipation at TL = 25°C, Pb-free Surmetic 40 plastic package, and ±5% tolerance-critical for stable reference design in industrial power supplies and automotive subsystems.
Technical Context
The 1N5350BRLG operates as a silicon-oxide passivated junction Zener diode optimized for tight voltage regulation under DC and transient conditions. Its thermal design relies on junction-to-lead thermal resistance (θJL = 25 °C/W) and lead-length-dependent derating, enabling reliable operation up to +150°C continuous junction temperature.
It delivers stable regulation across varying load currents due to low dynamic impedance (100 Ω @ IZT = 2.5 mA) and controlled leakage (<0.25 mA @ VR = 7.0 V). The device supports non-repetitive surge events up to 100 A at 8.3 ms pulse width without degradation, validated per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V (±5% tolerance at IZT = 2.5 mA; defines regulated output voltage accuracy) |
| Power Dissipation (PD) | 5 W at TL = 25°C (maximum continuous power handling before thermal derating applies) |
| Zener Impedance (ZZT) | 100 Ω max @ IZT = 2.5 mA (low dynamic resistance ensures minimal voltage shift under load variation) |
| Surge Current (IR) | 100 A peak @ 8.3 ms (enables robust transient overvoltage clamping without failure) |
| Leakage Current (IR) | 0.25 mA max @ VR = 7.0 V (low reverse leakage preserves efficiency in high-impedance bias networks) |
| ESD Rating | Class 3 (>16 kV HBM) (ensures survivability during board handling and assembly) |
| Junction Temp Range | −65°C to +200°C (supports operation in harsh environments including automotive under-hood) |
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.

Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5350BRL | Identical electrical specs; differs only in packaging-tape-and-reel vs. bulk box (no Pb-free marking) | Same functional use; requires Pb-free compliance verification for final product certification | Select 1N5350BRLG when RoHS/REACH documentation and Pb-free traceability are mandatory |
| BZX85C13 | 1.3 W power rating, 13 V ±5%, higher ZZT (≥200 Ω), lower surge rating (40 A) | Suitable only for low-power biasing-not for 5 W regulation or high-energy clamping | Choose BZX85C13 only for space-constrained PCBs where thermal mass and surge immunity are secondary |
Compared with 1N5350BRLG, the 1N5350BRL offers identical performance but lacks Pb-free certification documentation, while BZX85C13 sacrifices 74% power handling and 60% surge capacity-making 1N5350BRLG the sole choice for robust 5 W regulation in industrial or automotive settings.

FAQ
What is the nominal zener voltage and tolerance of the 1N5350BRLG?
The 1N5350BRLG has a nominal zener voltage of 13 V with a guaranteed tolerance of ±5%, corresponding to a minimum of 12.35 V and maximum of 13.65 V at IZT = 2.5 mA. This tolerance is JEDEC-standard for B-suffix devices and is fully tested and binned during manufacturing. The 1N5350BRLG maintains this specification across its rated operating temperature range of −65°C to +150°C (DC).
How much power can the 1N5350BRLG dissipate continuously?
The 1N5350BRLG is rated for 5 W steady-state power dissipation at a lead temperature (TL) of 25°C with 3/8-inch lead length. Above 25°C, it derates linearly at 40 mW/°C. At TL = 100°C, its usable power drops to 2 W. Thermal performance depends on PCB copper area and lead length-actual dissipation must be verified using θJL = 25 °C/W and junction temperature limits.
Does the 1N5350BRLG have surge protection capability, and what is its rating?
Yes, the 1N5350BRLG supports non-repetitive surge currents up to 100 A with an 8.3 ms pulse width, per Figure 5 in the onsemi datasheet. This rating is validated under standardized square-wave testing and enables direct use in load-dump and inductive-switching protection without supplemental TVS devices. The 1N5350BRLG retains full functionality after such events if junction temperature remains below 200°C.
What is the package type and lead finish of the 1N5350BRLG?
The 1N5350BRLG uses the axial-lead Surmetic 40 plastic package (Case 017AA), with corrosion-resistant, readily solderable leads rated for 260°C for 10 seconds at 1/16 inch from the case. The "G" suffix confirms Pb-free construction compliant with RoHS Directive 2011/65/EU and J-STD-020 moisture sensitivity level 1. Polarity is marked by a cathode band near the lead end.
What is the maximum reverse leakage current for the 1N5350BRLG, and at what voltage is it specified?
The 1N5350BRLG specifies a maximum reverse leakage current (IR) of 0.25 mA at VR = 7.0 V, measured at TA = 25°C. This low leakage ensures minimal quiescent current draw in high-impedance bias networks and preserves regulation accuracy in low-power standby modes. Leakage increases with temperature but remains below 1 mA up to TJ = 125°C per typical curves in the datasheet.
