Product details
Overview
1N4753CE3/TR13 from Microsemi is a 1.0 W, 36 V ±2% tolerance silicon Zener diode in DO-41 plastic package, rated for 7.0 mA test current, 50 Ω dynamic impedance at IZT, and 1000 mA maximum regulator current at TL = 50°C. It provides precision voltage regulation in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4753CE3/TR13 datasheet, 1N4753CE3/TR13 pinout, 1N4753CE3/TR13 application, or 1N4753CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (45°C/W junction-to-lead), surge current rating (1000 mA), RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR13).
Technical Context
This Zener operates in reverse breakdown to maintain stable output voltage across wide current (1–1000 mA) and temperature (−65°C to +150°C) ranges. Its 2% voltage tolerance (C suffix) and low 50 Ω dynamic impedance ensure tight regulation under varying load conditions.
The DO-41 axial-leaded package delivers 45°C/W junction-to-lead thermal resistance at 10 mm lead length, enabling reliable 1.0 W dissipation at TL ≤ 105°C. Polarity is marked by cathode band; regulation requires cathode-positive bias relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±2% at 7.0 mA - ensures precise reference voltage with minimal drift in feedback loops |
| Power Dissipation | 1.0 W at TL ≤ 105°C - supports continuous regulation in compact linear supplies without forced cooling |
| Dynamic Impedance (ZZT) | 50 Ω @ 7.0 mA - limits output voltage variation under dynamic load changes |
| Max Regulator Current (IZM) | 1000 mA at TL = 50°C - enables robust shunt regulation for moderate-current references |
| Reverse Leakage (IR) | 5 μA @ 28.8 V - guarantees low standby power loss in high-impedance bias networks |
| Thermal Resistance | 45°C/W junction-to-lead - allows direct thermal path to PCB copper or heatsink via leads |
| Operating Temp Range | −65°C to +150°C - suitable for industrial and automotive under-hood applications |
Pinout & Package
DO-41 (DO-204AL) plastic axial-leaded package with cathode indicated by color band; anode and cathode terminals are non-polarized for mounting but require cathode-positive bias during Zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground node | Connected to circuit ground or lower potential; forms return path for Zener current |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; must be held positive relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance | Enables accurate voltage references without post-calibration in analog power supplies |
| RoHS-compliant matte-tin plating | Ensures solderability per MIL-STD-750 Method 2026 and compatibility with lead-free reflow |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for SMT assembly lines |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for ESD-protected workstations |
| Tape-and-reel packaging (TR13) | Supports automated pick-and-place placement with standard EIA-296 carrier tape |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4753A | Same 36 V ±5% tolerance, no "e3" RoHS marking, no TR13 tape-and-reel | Requires leaded-solder process; unsuitable for RoHS-compliant production | Select only for legacy repair or non-RoHS prototyping |
| MMSZ4706T1G | Surface-mount SOD-123 package, 36 V ±5%, 500 mW rating, 30 Ω ZZT | Lower power and smaller footprint; not drop-in replacement for through-hole designs | Choose for space-constrained PCBs where 1.0 W dissipation is unnecessary |
Compared with 1N4753A and MMSZ4706T1G, the 1N4753CE3/TR13 uniquely combines 1.0 W power handling, ±2% tolerance, RoHS compliance, and tape-and-reel readiness-making it optimal for high-reliability, volume-manufactured industrial power references requiring long-term supply continuity.

FAQ
What is the Zener voltage tolerance of the 1N4753CE3/TR13?
The 1N4753CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in the part number. This means its nominal 36 V Zener voltage is guaranteed between 35.28 V and 36.72 V when measured at 7.0 mA test current and 25°C lead temperature. This tighter tolerance supports high-accuracy voltage references compared to standard ±5% variants like the 1N4753A.
Does the 1N4753CE3/TR13 meet RoHS requirements?
Yes, the 1N4753CE3/TR13 meets RoHS requirements, as confirmed by the "e3" suffix indicating RoHS-compliant matte-tin plating per Microsemi's documentation. The device uses annealed matte-tin terminations solderable per MIL-STD-750 Method 2026 and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
What is the maximum power dissipation capability of the 1N4753CE3/TR13?
The 1N4753CE3/TR13 is rated for 1.0 W steady-state power dissipation at lead temperature (TL) ≤ 105°C with 10 mm lead length from body, or at ambient temperature (TA) ≤ 45°C when mounted on FR4 with specified copper pads. Derating is required above these temperatures, per Figure 1 in the Microsemi datasheet.
How is polarity identified on the 1N4753CE3/TR13?
Polarity on the 1N4753CE3/TR13 is identified by a single color band marking the cathode terminal. For proper Zener regulation, the banded (cathode) end must be held positive with respect to the unmarked (anode) end. Forward voltage is ≤1.2 V at 200 mA, confirming standard silicon diode behavior in forward bias.
What does the "TR13" suffix indicate in 1N4753CE3/TR13?
"TR13" indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format enables automated surface-mount or through-hole placement using standard pick-and-place equipment. The "TR" suffix is added to denote reel packaging, while "13" specifies reel diameter-not quantity or orientation.
