Product details
Overview
1N5341BRL 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 765 mA maximum DC zener current. It regulates voltage in low-power reference and protection circuits, such as power supply feedback loops and overvoltage clamp stages in industrial sensor interfaces.
For engineers reviewing the 1N5341BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.2 V regulation point, 200 Ω dynamic impedance, 12.4 V reverse breakdown threshold, 0.1 µA leakage at 5 V, 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 steady-state and transient surge conditions. Its thermal design relies on lead-to-ambient conduction, with junction-to-lead thermal resistance of 25 °C/W at 3/8″ lead length and derating of 40 mW/°C above 25 °C.
The 1N5341BRL delivers tight regulation across temperature via a compensated junction structure, exhibiting a positive temperature coefficient typical of 6–7 V Zeners. It supports non-repetitive 180 W surge capability at 8.3 ms pulse width and maintains ≤0.1 µA reverse leakage at VR = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal (5.89–6.51 V range), defines precise regulation point for feedback networks |
| Power Dissipation | 5 W at TL = 25°C, sets maximum continuous clamping energy in protection circuits |
| Zener Impedance (ZZT) | 200 Ω max @ IZT = 1 mA, determines output voltage stability under load variation |
| Max DC Zener Current (IZM) | 765 mA, derived from 5 W / 6.2 V, limits safe operating current in shunt regulator designs |
| Reverse Leakage (IR) | 0.1 µA max @ VR = 5 V, ensures minimal quiescent current in battery-powered references |
| Surge Rating | 180 W @ 8.3 ms, enables transient overvoltage suppression without failure |
| ESD Rating | Class 3 (>16 kV HBM), provides robust handling in manual assembly and field service |
Pinout & Package

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 in bulk box (1000 units), not tape-and-reel; identical Surmetic 40 package and marking | No functional difference; selected when reel packaging is unnecessary for hand-soldering or low-volume prototyping | Choose 1N5341B for lab evaluation or small-batch builds where automated placement is not required. |
| BZX84-C6V2 | SOT-23 surface-mount package, 6.2 V ±5%, 300 mW rating, 60 Ω ZZT, higher leakage (0.5 µA @ 5 V) | Lower power handling and different thermal path; suited for space-constrained PCBs but not direct replacement in 5 W designs | Use BZX84-C6V2 only in low-power, high-density layouts where 5 W dissipation is not needed and thermal management differs. |
Compared with 1N5341BRL, the 1N5341B offers identical performance in a different packaging format, while BZX84-C6V2 trades power capability and thermal robustness for footprint reduction-making it unsuitable for high-energy clamping but viable for compact reference generation.

FAQ
What is the zener voltage tolerance of the 1N5341BRL?
The 1N5341BRL has a ±5% zener voltage tolerance, meaning its actual breakdown voltage falls between 5.89 V and 6.51 V at the specified test current of 1 mA. This tolerance is guaranteed per JEDEC standard and applies across the full operating temperature range of −65°C to +200°C, ensuring consistent regulation performance in demanding environments.
Can the 1N5341BRL be used in surface-mount designs?
No, the 1N5341BRL uses an axial-lead Surmetic 40 package (Case 017AA) intended for through-hole mounting. It is not compatible with SMT reflow processes. For surface-mount alternatives, consider the BZX84-C6V2 (SOT-23) or MMBZ5231B (SOT-23), though these have lower power ratings and different impedance characteristics than the 1N5341BRL.
What is the maximum surge current the 1N5341BRL can handle?
The 1N5341BRL supports a peak non-repetitive surge current of up to 180 W for 8.3 ms, corresponding to approximately 29 A at 6.2 V. This rating is validated per onsemi's test methodology using square-wave pulses and assumes proper lead-to-heatsink thermal path. Exceeding this limit risks irreversible junction damage.
How does the 1N5341BRL's zener impedance affect regulation accuracy?
The 1N5341BRL's maximum zener impedance of 200 Ω at 1 mA means that a 1 mA change in zener current causes up to a 200 mV shift in regulated voltage. In practice, this low impedance ensures minimal output variation under dynamic load changes-critical for maintaining stability in feedback loops and reference circuits where the 1N5341BRL is deployed.
Is the 1N5341BRL RoHS compliant and lead-free?
Yes, the 1N5341BRL is Pb-free and RoHS compliant, as indicated by the "G" suffix in its full ordering code (1N5341BRLG). The device uses lead-free terminations and conforms to EU Directive 2011/65/EU, making it suitable for export-controlled and environmentally regulated industrial and automotive applications without restriction.
