Product details
Overview
1N4754CE3/TR13 from Microsemi is a 39 V, ±2% tolerance, 1 W axial-lead Zener diode in DO-41 package, rated for 6.5 mA test current, 23 Ω dynamic impedance at IZT, and 1000 mA maximum regulator current at TA = 50°C. It delivers stable voltage regulation in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the 1N4754CE3/TR13 datasheet, 1N4754CE3/TR13 pinout, 1N4754CE3/TR13 application, or 1N4754CE3/TR13 equivalent, key selection criteria include its tight 2% VZ tolerance, low ZZT of 23 Ω, RoHS-compliant matte-tin plating, and TR13 tape-and-reel packaging for automated assembly.
Technical Context
This device operates in reverse breakdown to maintain a stable 39 V reference across a wide current range (5–115 mA), with thermal resistance of 45 °C/W junction-to-lead (3/8" lead length) and 105 °C/W junction-to-ambient on FR4 board. Its knee impedance is 25 Ω at 0.25 mA test current, supporting precise low-current regulation.
Designed for DC voltage regulation, it features a cathode band polarity indicator, 1.2 V forward voltage max at 200 mA, and ESD insensitivity per MIL-STD-750 Method 1020. Moisture sensitivity level is IPC/JEDEC J-STD-020B Level 1 - no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 39 V ±2% at 6.5 mA - ensures tight reference accuracy for feedback loops and precision clamping |
| Power Dissipation | 1.0 W at TL < 105°C - supports continuous operation in compact PCB layouts with adequate lead heatsinking |
| Dynamic Impedance (ZZT) | 23 Ω at IZT = 6.5 mA - minimizes output voltage variation under load transients |
| Max Regulator Current (IZM) | 1000 mA at TA = 50°C - enables robust shunt regulation in medium-power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4754A | Same 39 V, ±2%, DO-41, but lacks e3 RoHS and TR13 tape-and-reel packaging | Requires manual handling and Pb-based soldering; not suitable for lead-free SMT lines | Select only for legacy repair or non-RoHS prototyping where packaging flexibility is secondary |
| MMSZ4702T1G | Surface-mount SOD-123, 39 V ±5%, 500 mW, ZZT = 45 Ω - lower power, looser tolerance, different footprint | Used in space-constrained consumer electronics; not drop-in replaceable due to package and power rating mismatch | Choose when board area is critical and ±5% tolerance is acceptable; requires PCB redesign |
Compared with 1N4754A and MMSZ4702T1G, the 1N4754CE3/TR13 uniquely combines tight ±2% tolerance, 1 W power capability, RoHS compliance, and tape-and-reel readiness - making it optimal for high-reliability industrial power supplies requiring both precision and manufacturability.

FAQ
What is the Zener voltage tolerance of the 1N4754CE3/TR13?
The 1N4754CE3/TR13 has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in the part number. This means its nominal 39 V breakdown voltage is guaranteed between 38.22 V and 39.78 V when measured at 6.5 mA test current and 25°C lead temperature. This tighter tolerance supports higher-accuracy voltage references compared to standard ±5% (A suffix) or ±10% (no suffix) variants.
Does the 1N4754CE3/TR13 meet RoHS requirements?
Yes, the 1N4754CE3/TR13 meets RoHS requirements, as confirmed by the "e3" suffix denoting RoHS-compliant annealed matte-tin plating. It is fully compliant with Directive 2011/65/EU and subsequent amendments, with lead content below 1000 ppm and no restricted substances above threshold limits. The device is suitable for lead-free reflow processes up to 260°C for 10 seconds.
What is the maximum continuous power dissipation for the 1N4754CE3/TR13?
The 1N4754CE3/TR13 has a maximum continuous power dissipation of 1.0 W at lead temperature (TL) below 105°C with 3/8" (10 mm) lead length from body, or at ambient temperature (TA) below 45°C when mounted on an FR4 PCB with specified copper pad geometry. Derating is required above these temperatures per Figure 1 in the Microsemi datasheet.
Can the 1N4754CE3/TR13 be used in surface-mount designs?
No, the 1N4754CE3/TR13 uses a DO-41 axial-lead package and is not suitable for surface-mount assembly. For SMT equivalents, Microsemi offers the SMAJ4754A (SMA package) and MLL4754A (SOD-123 variant), though neither matches the 1N4754CE3/TR13's ±2% tolerance or 1 W rating exactly. Board redesign and validation would be required for SMT migration.
What does the "TR13" suffix indicate in 1N4754CE3/TR13?
"TR13" indicates tape-and-reel packaging on a 13-inch reel per EIA-296 standard, enabling automated pick-and-place assembly. The "TR" denotes tape-and-reel format, while "13" specifies reel diameter. This packaging ensures consistent orientation (cathode band aligned), moisture protection, and compatibility with high-volume SMT lines - a key advantage over bulk or ammo-pack alternatives for production use.
