Product details
Overview
1N5352BRL from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 15 V (±5%), maximum zener impedance of 75 Ω at 2.5 mA test current, and surge rating of up to 180 W for 8.3 ms. It features silicon-oxide passivated junction, ESD rating >16 kV (HBM), and operates across −65°C to +200°C. It serves as a precision voltage reference or shunt regulator in DC power supply feedback paths.
For engineers reviewing the 1N5352BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its 15 V regulation tolerance, low 75 Ω dynamic impedance at IZT = 2.5 mA, thermal resistance θJL = 25 °C/W, 11.5 V minimum zener voltage, and 6.3 A maximum DC zener current under rated power.
Technical Context
The 1N5352BRL uses a silicon-oxide passivated junction to achieve tight voltage tolerance (±5%) and stable regulation over temperature. Its zener voltage is specified at two test currents-10% and 50% of IZM-to characterize regulation linearity, with a temperature coefficient of +9.5 mV/°C typical for the 15 V variant.
Thermal performance is defined by junction-to-lead resistance (θJL = 25 °C/W) and derating above 25°C (40 mW/°C). The device supports non-repetitive surge currents up to 180 W for 8.3 ms, validated per JEDEC standards using square-wave pulses with controlled lead mounting geometry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25–15.75 V @ IZT = 2.5 mA - defines regulated output range under standard test conditions |
| Max Power Dissipation | 5 W @ TL = 25°C - sets absolute steady-state power limit before thermal derating begins |
| Zener Impedance | 75 Ω max @ IZT = 2.5 mA - determines output voltage variation under load transients |
| Leakage Current | 0.25 mA max @ VR = 11.5 V - ensures minimal quiescent current in standby regulation mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5352B | Same electrical specs but in bulk box (1000 units), not tape-and-reel; identical axial package and marking | No functional difference; used where automated pick-and-place is not required | Select 1N5352BRL for SMT production lines requiring tape-and-reel delivery; choose 1N5352B for manual prototyping or low-volume hand assembly |
| BZX85C15 | 1.3 W rating, 15 V ±5%, 20 Ω ZT @ 5 mA - lower power, lower impedance, TO-204AA (DO-41) package | Suitable only for sub-1 W regulation; cannot replace 1N5352BRL in 5 W applications without thermal redesign | Use BZX85C15 only in space-constrained, low-power designs where 5 W dissipation is unnecessary; verify thermal margin with θJA = 125 °C/W |
Compared with 1N5352B and BZX85C15, the 1N5352BRL delivers full 5 W capability in tape-and-reel format with superior surge immunity (180 W vs. ~40 W), making it optimal for production-grade power supply regulation where reliability and manufacturability are critical.

FAQ
What is the zener voltage tolerance of the 1N5352BRL?
The 1N5352BRL has a zener voltage tolerance of ±5% at 25°C, with a specified range of 14.25 V to 15.75 V at IZT = 2.5 mA. This tolerance is guaranteed per JEDEC standard and applies to all units marked with the "B" suffix. The 1N5352BRL achieves this tight tolerance through silicon-oxide passivated junction processing and 100% electrical screening during manufacturing.
How does the 1N5352BRL handle surge conditions?
The 1N5352BRL supports a non-repetitive peak surge current of up to 180 W for 8.3 ms, verified per JEDEC test methodology using square-wave pulses. This capability allows the 1N5352BRL to safely clamp transient overvoltages in power rails without degradation. Its axial lead construction and thermal design ensure reliable energy absorption when mounted with 3/8″ lead length to heatsink.
Is the 1N5352BRL RoHS compliant and lead-free?
Yes, the 1N5352BRL is Pb-free and RoHS compliant, as indicated by the "G" suffix in its ordering code. It uses a transfer-molded thermosetting plastic package with corrosion-resistant, readily solderable leads. The 1N5352BRL meets J-STD-609 Category 1 moisture sensitivity and is qualified for lead-free reflow profiles up to 260°C for 10 seconds at 1/16″ from case.
What is the maximum DC zener current for the 1N5352BRL?
The maximum DC zener current (IZM) for the 1N5352BRL is 75 mA at 25°C ambient, calculated from its 5 W power rating divided by the nominal 15 V zener voltage. At elevated temperatures, IZM must be reduced linearly per the 40 mW/°C derating factor above 25°C. The 1N5352BRL sustains this current continuously when properly heatsinked and within its −65°C to +150°C DC operating range.
Can the 1N5352BRL be used in place of the 1N5352B?
Yes, the 1N5352BRL is functionally identical to the 1N5352B in all electrical, thermal, and mechanical specifications-the only difference is packaging format: 1N5352BRL is supplied in 4000-unit tape-and-reel for automated assembly, while 1N5352B comes in 1000-unit boxes. Both share the same Case 017AA axial package, marking, and onsemi qualification. The 1N5352BRL is the preferred choice for SMT production lines.
