Product details
Overview
1N5340BRL from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 6.0 V, ±5% tolerance, 200 Ω maximum zener impedance at 1 mA test current, and 790 mA maximum DC zener current. It operates as a precision voltage reference or shunt regulator in low-power linear power supplies and overvoltage protection circuits.
For engineers reviewing the 1N5340BRL datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage stability under 1 mA to 790 mA bias, thermal resistance (25 °C/W junction-to-lead), surge capability (180 W @ 8.3 ms), ESD robustness (>16 kV HBM), and Pb-free axial package compatibility with wave soldering at 260 °C.
Technical Context
This device implements a silicon-oxide passivated PN junction optimized for stable reverse-biased breakdown regulation. Its zener voltage is specified at IZT = 1 mA with tight ±5% limits and exhibits a positive temperature coefficient above 5 V, typical for 6 V-class units.
It delivers regulated output by maintaining near-constant voltage across its terminals when reverse-biased above VZ, with dynamic impedance defined at both IZT (200 Ω) and IZK (300 Ω), supporting predictable load regulation in simple shunt configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.70–6.30 V at IZT = 1 mA - defines regulation setpoint with ±5% tolerance for stable reference generation |
| Max Power Dissipation | 5 W @ TL = 25°C - sets absolute upper limit for continuous DC power handling in lead-mounted configuration |
| Zener Impedance (ZZT) | 200 Ω max @ IZT = 1 mA - determines output voltage variation under small-signal load changes |
| Max DC Zener Current (IZM) | 790 mA - derived from 5 W / 6.3 V; defines maximum safe steady-state reverse conduction |
| Surge Rating | 180 W @ 8.3 ms - enables transient overvoltage clamping without failure during short-duration spikes |
| ESD Rating | Class 3 (>16 kV) per HBM - ensures robustness against handling-induced electrostatic discharge |
| Junction-to-Lead RθJL | 25 °C/W - quantifies thermal path efficiency from die to leads; critical for derating above 25°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5340B | Same electrical specs and package; differs only in packaging format (bulk vs. tape-and-reel) | No functional difference; identical performance in PCB layout and thermal management | Select 1N5340BRL for automated SMT placement; choose 1N5340B for manual prototyping or low-volume hand assembly |
| MMBZ5234B | Surface-mount SOT-23 package; 6.0 V nominal, but rated for 0.5 W only and 100 Ω ZZT | Not suitable for >500 mW continuous dissipation; limited surge capability (50 W) | Use MMBZ5234B only in space-constrained, low-power signal-level applications where 5 W rating is unnecessary |
Compared with 1N5340BRL, the 1N5340B offers identical electrical behavior but lacks tape-and-reel logistics support, while MMBZ5234B trades power handling and surge robustness for miniaturization-making 1N5340BRL optimal for industrial power regulation where reliability under sustained load and transient stress is mandatory.

FAQ
What is the exact zener voltage tolerance and test condition for 1N5340BRL?
The 1N5340BRL has a ±5% zener voltage tolerance, specified as 5.70 V minimum to 6.30 V maximum at IZT = 1 mA, with 40 ±10 ms current application prior to measurement. This tolerance applies strictly to the B-suffix device per JEDEC standard and is guaranteed across manufacturing lots.
Can 1N5340BRL be used in surface-mount designs?
No, 1N5340BRL is an axial-lead through-hole device in Case 017AA plastic package and is not compatible with SMT assembly. For surface-mount alternatives, consider the MMBZ5234B (SOT-23, 0.5 W) or NZ9F6V2T5G (SOD-123, 0.5 W), though neither matches the 5 W rating or surge capability of the 1N5340BRL.
What is the maximum allowable lead temperature during soldering of 1N5340BRL?
The maximum lead temperature for soldering 1N5340BRL is 260°C, applied for no more than 10 seconds at a distance of 1/16 inch (1.59 mm) from the case body. Exceeding this profile risks internal bond wire damage or delamination of the oxide-passivated junction.
How does thermal derating work for 1N5340BRL above 25°C ambient?
1N5340BRL must be derated at 40 mW/°C above 25°C ambient when lead length is 3/8 inch. At 75°C ambient, maximum power drops to 3 W (5 W − 40 mW/°C × 50°C). Derating depends on actual lead-to-ambient thermal resistance, which varies with PCB copper area and airflow.
Is 1N5340BRL compliant with RoHS and REACH regulations?
Yes, 1N5340BRL is Pb-free and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "G" suffix in ordering code confirms compliance, and material declarations are available in onsemi's Product Compliance Database.
