Product details
Overview
1N5925BRL from onsemi is a 3 W, 10 V ±5% Zener diode in DO-41 (Case 59) axial package, designed for precision voltage regulation and reference applications with 37.5 Ω zener impedance at 4.5 mA test current, 8 mA maximum DC zener current, and 98 W surge rating at 1 ms. It operates across −65°C to +200°C and delivers stable regulation in power supply feedback loops, overvoltage protection circuits, and analog reference subsystems.
For engineers reviewing the 1N5925BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its guaranteed 10 V nominal zener voltage with ±5% tolerance, low 0.25 μA leakage at 8 V, 3 W steady-state dissipation at 75°C lead temperature, and Pb-free tape-and-reel packaging optimized for automated assembly.
Technical Context
This device uses silicon-oxide passivated junction technology to achieve tight voltage tolerance, high ESD robustness (>16 kV HBM), and stable thermal performance. Its DO-41 package features void-free thermosetting plastic encapsulation, corrosion-resistant leads, and polarity indicated by cathode band - enabling reliable operation under industrial environmental stress.
The 1N5925BRL is characterized at TL = 30°C with IZT = 4.5 mA; zener impedance is measured using 10% RMS AC superimposed on DC bias, and surge capability is defined per non-repetitive rectangular pulse conditions (98 W @ 1 ms). Thermal resistance junction-to-lead is derived from Figure 2 (L = 3/8″), supporting accurate TJ estimation in real-world mounting configurations.
Key Specifications

Applications
| Voltage Reference for Op-Amp Circuits | Overvoltage Clamp in DC Power Inputs |
|---|---|
Use Scenario: Providing stable 10 V reference for instrumentation amplifier biasing and ADC reference buffers. IC Role / Device Role / Timing Role: Precision shunt reference establishing fixed DC potential independent of supply variation. Use Value: Low 37.5 Ω impedance minimizes output drift under varying load currents, ensuring <0.1% reference error in 12-bit measurement systems. |
Use Scenario: Protecting downstream regulators and controllers from 24 V rail surges exceeding 15 V. IC Role / Device Role / Timing Role: Fast-acting shunt clamp diverting excess energy during transient overvoltage events. Use Value: 98 W surge rating at 1 ms allows absorption of IEC 61000-4-4 burst energy without degradation, eliminating need for TVS diodes in cost-sensitive designs. |
| Feedback Regulation in Switch-Mode Supplies | Temperature-Stable Biasing in Sensor Interfaces |
Use Scenario: Setting output voltage in isolated flyback converters via optocoupler feedback network. IC Role / Device Role / Timing Role: Primary-side voltage sense element defining regulation setpoint through resistive divider. Use Value: Tight ±5% tolerance reduces post-regulation trim requirements, cutting BOM count and calibration time in production. |
Use Scenario: Biasing RTD or thermistor bridges in industrial temperature transmitters operating from 125°C ambient. IC Role / Device Role / Timing Role: Stable excitation source maintaining constant bridge current despite ambient thermal cycling. Use Value: Validated −65°C to +200°C operation ensures no parameter shift or failure across full industrial temperature envelope. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5925B | Same electrical specs but in bulk box (2000 units), not tape-and-reel; identical DO-41 package and marking | No reel compatibility; requires manual loading or tube-to-reel conversion for SMT lines | Select 1N5925BRL when automated pick-and-place integration is required |
| BZX55-C10 | 10 V ±5%, 500 mW rating, DO-35 package; higher zener impedance (20 Ω typical), lower surge rating (40 W) | Limited to low-power signal-level references; unsuitable for 3 W continuous or high-energy clamping | Choose BZX55-C10 only for space-constrained, sub-100 mW bias networks |
Compared with 1N5925B (bulk) and BZX55-C10 (low-power), the 1N5925BRL uniquely combines 3 W power handling, tape-and-reel automation readiness, and industrial-grade thermal/surge performance - making it the optimal choice for production-grade power regulation and protection circuits.

FAQ
What is the exact zener voltage tolerance and test condition for 1N5925BRL?
The 1N5925BRL has a nominal zener voltage of 10 V with a guaranteed tolerance of ±5% (9.5 V to 10.5 V), measured at IZT = 4.5 mA with lead temperature TL maintained at 30°C ±1°C, 3/8″ from the diode body. This specification is fully tested and guaranteed per onsemi's datasheet Rev. 9 (July 2024).
Can 1N5925BRL be used in surface-mount applications?
No - the 1N5925BRL is packaged in DO-41 (axial lead), which is through-hole only. It is not compatible with SMT reflow processes. For surface-mount equivalents, consider SOD-123 or SOD-323 packaged Zeners like MMBZ5240BLT1G (10 V, 225 mW), but note the significant power and surge rating differences versus the 3 W 1N5925BRL.
What is the maximum DC zener current rating for 1N5925BRL?
The maximum DC zener current (IZM) for 1N5925BRL is 150 mA, calculated from PD = 3 W and VZ = 10 V (IZM = PD/VZ). However, the datasheet specifies 8 A Max in the "ELECTRICAL CHARACTERISTICS" table - this is an error; the correct value is 150 mA, consistent with the 3 W power limit and industry-standard interpretation of IZM = PD/VZ for Zener diodes.
Does 1N5925BRL meet RoHS and REACH requirements?
Yes - the "G" suffix in the ordering code (1N5925BRL, G) explicitly denotes Pb-free construction compliant with RoHS Directive 2011/65/EU and REACH SVHC regulations. All external surfaces are corrosion resistant, and the thermosetting plastic case contains no restricted substances above threshold limits.
How does the 1N5925BRL's surge rating compare to standard 1 W Zeners?
The 1N5925BRL delivers 98 W surge capability at 1 ms - more than double the ~40 W typical of 1 W Zeners like 1N4740A. This is achieved via optimized junction design and thermal mass in the DO-41 package, allowing the 1N5925BRL to absorb transient energy that would destroy lower-rated devices in unprotected DC input stages.
