Product details
Overview
1N5341BRLG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 6.2 V, ±5% tolerance, 200 Ω maximum zener impedance at 1 mA test current, and 0.1 µA maximum reverse leakage at 5.0 V. It delivers stable voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation for industrial power converters and embedded control systems.
For engineers reviewing the 1N5341BRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.2 V nominal regulation, 5 W steady-state power rating, Pb-free Surmetic 40 package, and Class 3 ESD robustness (>16 kV HBM).
Technical Context
This discrete Zener diode uses silicon-oxide passivated junction technology to achieve tight voltage tolerance and low dynamic impedance. Its thermal design supports 5 W dissipation at 25°C lead temperature with 25 °C/W junction-to-lead thermal resistance and derating above ambient.
The device operates across −65°C to +200°C storage and operating range (DC max 150°C), with surge capability up to 180 W for 8.3 ms pulses. Polarity is marked by cathode band; mounting position is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 6.2 V - precise DC reference voltage under 1 mA test current (IZT) |
| Zener Tolerance | ±5% - ensures VZ stays within 5.89–6.51 V across production lot |
| Max Zener Impedance | 200 Ω @ IZT = 1 mA - low dynamic resistance enables stable regulation under load transients |
| Steady-State Power | 5 W @ TL = 25°C - supports continuous regulation in compact power supplies without heatsinking |
| Reverse Leakage | 0.1 µA @ VR = 5.0 V - minimal standby current preserves efficiency in battery-backed or low-power circuits |
| ESD Rating | Class 3 (>16 kV HBM) - withstands handling and board-level electrostatic discharge without parameter shift |
| Surge Rating | 180 W @ 8.3 ms - clamps transient overvoltages such as inductive kickback or lightning-induced surges |

IC Role / Device Role / Timing Role: Zener reference diode providing precise 6.2 V threshold to TL431 shunt regulator input. Use Value: Maintains ±1% output regulation across line/load/temperature with minimal drift due to low tempco and tight VZ tolerance. | Use Scenario: Placed across DC bus of 24 V industrial PLC I/O module to suppress switching transients. IC Role / Device Role / Timing Role: Standalone overvoltage clamp absorbing energy from relay coil flyback or motor commutation spikes. Use Value: Limits bus voltage to ≤6.51 V during 8.3 ms surges up to 180 W, preventing damage to 5 V logic ICs and ADC inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5341B | Same electrical specs but SnPb lead finish; not Pb-free | Not compliant with RoHS or J-STD-020 reflow standards requiring Pb-free assembly | Select only for legacy repair or non-RoHS-compliant production lines |
| BZX85C6V2 | 500 mW rating, 6.2 V ±5%, TO-204AA (DO-41) package, 100 Ω Zzt | Limited to low-power applications; insufficient for 5 W continuous dissipation or high-energy surge clamping | Use where space constraints or cost drive selection, but verify thermal margin and surge headroom |
Compared with 1N5341BRLG, 1N5341B lacks RoHS compliance and requires different process controls, while BZX85C6V2 offers smaller footprint and lower cost but sacrifices 90% of power handling and surge capacity-making it unsuitable for primary regulation or high-energy protection roles.

FAQ
What is the nominal zener voltage and tolerance of the 1N5341BRLG?
The 1N5341BRLG has a nominal zener voltage of 6.2 V with a guaranteed tolerance of ±5%, meaning its actual VZ falls between 5.89 V and 6.51 V at 1 mA test current (IZT) under 25°C conditions. This tight tolerance is achieved via silicon-oxide passivated junction technology and is specified per JEDEC standards for B-suffix devices.
Can the 1N5341BRLG be used in surface-mount designs?
No, the 1N5341BRLG is an axial-lead device in JEDEC Case 017AA (Surmetic 40) plastic package and is not compatible with SMT assembly. It requires through-hole mounting with leads trimmed and formed. For surface-mount alternatives, consider SOD-123 or DO-214AC packaged Zeners-but note they differ in power rating, thermal performance, and surge capability versus the 5 W 1N5341BRLG.
What is the maximum steady-state power dissipation for the 1N5341BRLG?
The 1N5341BRLG is rated for 5 W maximum steady-state power dissipation at a lead temperature (TL) of 25°C, with linear derating of 40 mW/°C above that temperature. This rating assumes 3/8 inch lead length to heatsink; actual usable power depends on PCB copper area, airflow, and thermal interface to ambient.
How does the 1N5341BRLG perform under transient surge conditions?
The 1N5341BRLG supports up to 180 W non-repetitive surge power for 8.3 ms pulses, validated per Figure 5 in the onsemi datasheet. This enables reliable clamping of inductive switching transients and ESD-like events without parametric shift or failure, provided pulse duty cycle remains low and average power stays within 5 W limits.
Is the 1N5341BRLG RoHS compliant and halogen-free?
Yes, the "G" suffix in 1N5341BRLG denotes a Pb-free package compliant with RoHS Directive 2011/65/EU. The Surmetic 40 plastic body and leads meet JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and contain no intentionally added halogens per IEC 61249-2-21.
