Product details
Overview
1N4753PE3/TR8 from Microsemi is a 1.0 W axial-lead silicon Zener diode with nominal Zener voltage of 36 V, ±5% tolerance (A-suffix), 7.0 mA test current (IZT), 50 Ω dynamic impedance (ZZT), and 1000 mA maximum regulator current (IZM) at TA = 50°C. It operates across –65°C to +150°C and regulates voltage in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4753PE3/TR8 datasheet, 1N4753PE3/TR8 pinout, 1N4753PE3/TR8 application, or 1N4753PE3/TR8 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (45°C/W junction-to-lead), surge current rating (1000 mA), RoHS-compliant matte-tin plating, and DO-41 package compatibility with standard axial-lead PCB layouts.
Technical Context
This device functions as a precision voltage reference by operating in reverse breakdown, maintaining stable output voltage across wide current (1–1000 mA) and temperature (–65°C to +150°C) ranges. Its 36 V Zener voltage places it in the mid-range of the 1N47xxAP family, where temperature coefficient transitions from negative to positive near 5 V and becomes +0.075%/°C at 36 V per Figure 3.
The DO-41 plastic 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. It features void-free UL94V-0 epoxy body, cathode band polarity marking, and tin-lead or RoHS-compliant matte-tin terminations solderable per MIL-STD-750 Method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±5% at IZT = 7.0 mA - defines stable regulation point for feedback networks and clamp thresholds |
| Power Dissipation | 1.0 W at TL < 105°C - supports continuous operation in compact linear regulator or protection circuits |
| Dynamic Impedance (ZZT) | 50 Ω at IZT = 7.0 mA - determines output voltage variation under load transients |
| Max Regulator Current (IZM) | 1000 mA at TA = 50°C - sets upper limit for shunt current handling before thermal runaway |
| Thermal Resistance | 45°C/W junction-to-lead - enables direct heatsinking via leads; requires ≥10 mm lead length for rated power |
| Reverse Leakage (IR) | 5 μA max at VR = 27.4 V - ensures low standby power loss in high-impedance bias networks |
| Forward Voltage | 1.2 V max at IF = 200 mA - defines conduction drop when used in series forward-path configurations |
Pinout & Package
Package: DO-41 (JEDEC DO-204AL), axial-lead plastic molded case with cathode band marking. Body diameter 2.0–2.7 mm, overall length 4.5–5.5 mm, lead diameter 0.4–0.6 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded end | Connected to lower-potential node; carries full Zener current during regulation |
| Cathode | Banded end | Connected to higher-potential node; defines regulated output voltage referenced to anode |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant "e3" suffix | Matte-tin plating meets EU Directive 2011/65/EU and J-STD-020B Level 1 moisture sensitivity |
| Plastic P-suffix construction | Lower thermal resistance (45°C/W) vs. glass-body G-suffix variants, improving power handling |
| JEDEC 1N47xxA registration | Guaranteed interchangeability and standardized test conditions across qualified suppliers |
| ESD robustness | Nonsensitive per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in board-level design |
| Tape-and-reel packaging | "TR8" suffix indicates EIA-296 compliant 8 mm tape, enabling automated SMT placement with axial-lead adapters |

Use Value: 0.075%/°C tempco minimizes drift across –40°C to +85°C industrial ambient range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4753A | No "e3" RoHS suffix; Sn/Pb termination; same VZ, IZT, ZZT, IZM | Not suitable for RoHS-compliant production; identical electrical performance in non-regulated environments | Select 1N4753A only for legacy Sn/Pb assembly or prototyping where RoHS is not required |
| MMBZ5245BS-7-F | SOT-23 surface-mount; 36 V ±5%; 200 mW Pd; 100 Ω ZZT; 500 mA IZM | Limited power handling and higher impedance reduce stability in high-current regulation | Choose MMBZ5245BS-7-F only for space-constrained low-power signal clamping, not power rail regulation |
Compared with 1N4753A and MMBZ5245BS-7-F, the 1N4753PE3/TR8 offers full 1.0 W dissipation, lowest dynamic impedance (50 Ω), and RoHS compliance-making it optimal for industrial power supply references where thermal margin and regulatory compliance are critical.

FAQ
What is the Zener voltage tolerance of the 1N4753PE3/TR8?
The 1N4753PE3/TR8 has a nominal Zener voltage of 36 V with ±5% tolerance, indicated by the "A" suffix in its base part number. This tolerance is specified at IZT = 7.0 mA and TL = 25°C, and applies across the full operating temperature range of –65°C to +150°C per Microsemi's REV C datasheet.
Does the 1N4753PE3/TR8 require dry-pack moisture protection?
No, the 1N4753PE3/TR8 is moisture classified as IPC/JEDEC J-STD-020B Level 1, meaning it is not hygroscopic and does not require dry-packaging or baking prior to assembly. Its void-free thermosetting epoxy body inherently prevents moisture ingress during reflow or wave soldering.
What is the maximum surge current rating for the 1N4753PE3/TR8?
The 1N4753PE3/TR8 has a maximum surge current (ISM) rating of 1000 mA, measured using a ½ sine-wave pulse of 1/120 second duration at 25°C ambient. This rating validates its use in transient overvoltage suppression where short-duration energy spikes must be safely shunted without device failure.
Can the 1N4753PE3/TR8 be used in surface-mount designs?
The 1N4753PE3/TR8 is a DO-41 axial-lead device and is not inherently SMT-compatible. However, its "TR8" tape-and-reel packaging allows use with axial-lead feeders or adapter carriers in automated placement systems. For native SMT, consider Microsemi's SMAJ4753A or MLL4753A equivalents instead.
What is the thermal resistance specification for the 1N4753PE3/TR8?
The 1N4753PE3/TR8 has a junction-to-lead thermal resistance of 45°C/W when measured at 10 mm (3/8 inch) lead length from the body. When mounted on FR4 with 1 oz copper and defined pad geometry, its junction-to-ambient resistance rises to 105°C/W-critical for derating calculations in enclosed or high-ambient environments.
