Product details
Overview
1N4753APE3/TR8 from Microsemi is a 1.0 W axial-lead silicon Zener diode with a nominal Zener voltage of 36 V, ±5% tolerance (A suffix), 7.0 mA test current (IZT), 50 Ω dynamic impedance (ZZT), and 0.25 mA maximum reverse leakage at 27.4 V. It operates from –65°C to +150°C and regulates voltage in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4753APE3/TR8 datasheet, 1N4753APE3/TR8 pinout, 1N4753APE3/TR8 application, or 1N4753APE3/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 passive voltage reference by operating in reverse breakdown, maintaining stable regulation across 1.0 mA to 125 mA DC current range. Its 36 V nominal Zener voltage exhibits a positive temperature coefficient above 5 V, with typical TC near +0.075%/°C per Figure 3.
The DO-41 plastic package provides 105°C/W junction-to-ambient thermal resistance on FR4 board (1 oz Cu, 4 mm² pad), requiring derating above 45°C ambient. It meets MIL-STD-750 ESD immunity (Method 1020) and IPC/JEDEC J-STD-020B moisture sensitivity Level 1-no dry pack required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±5% at IZT = 7.0 mA - defines precise regulation point for feedback loops and clamp thresholds |
| Power Dissipation | 1.0 W at TL ≤ 105°C (3/8″ lead length) - sets maximum continuous DC power under defined thermal mounting |
| Dynamic Impedance | 50 Ω at IZT = 7.0 mA - determines output voltage variation under load transients |
| Reverse Leakage | 0.25 μA max at VR = 27.4 V - ensures minimal quiescent current in standby regulation |
| Surge Current | 1000 mA (½-sine, 1/120 s) - supports transient overvoltage clamping without failure |
| Thermal Resistance | 45°C/W junction-to-lead - enables thermal design using lead conduction path, not board conduction |
| Operating Temp | –65°C to +150°C - validated for industrial and automotive under-hood environments |

Applications
| Power Supply Voltage Reference | Overvoltage Clamp Circuit |
|---|---|
Use Scenario: Stabilizing feedback voltage in linear regulator ICs or discrete op-amp-based regulators. IC Role / Device Role / Timing Role: Provides precise 36 V reference to error amplifier input for output voltage setpoint. Use Value: Maintains ±5% regulation over 1–125 mA load range and –65°C to +150°C, reducing output drift. | Use Scenario: Protecting downstream 3.3 V or 5 V logic from 48 V bus transients in industrial control systems. IC Role / Device Role / Timing Role: Shunts excess energy to ground when bus voltage exceeds 36 V + tolerance margin. Use Value: Withstands 1000 mA surge pulses (1/120 s) without degradation, preventing latch-up or damage. |
| DC-DC Converter Feedback Network | Programmable Threshold Detector |
Use Scenario: Setting output voltage in isolated flyback converters using optocoupler feedback. IC Role / Device Role / Timing Role: Serves as primary-side Zener reference tied to TL431 secondary-side bias network. Use Value: 50 Ω dynamic impedance ensures stable loop gain across line/load variations. | Use Scenario: Triggering shutdown when battery voltage exceeds safe charging threshold in 24 V lead-acid systems. IC Role / Device Role / Timing Role: Acts as comparator input reference for discrete transistor latch or microcontroller ADC monitoring. Use Value: 0.25 μA max reverse leakage at 27.4 V minimizes false triggers during low-power sleep modes. |
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 plating only | Not compliant with EU RoHS or China RoHS; restricted in new designs targeting export markets | Select 1N4753APE3/TR8 for RoHS-mandated production; use 1N4753A only for legacy repair or non-regulated regions |
| MMSZ5245B-TP | Surface-mount SOD-123 package; 36 V ±5%, 100 mW rating | Lower power (0.1 W vs. 1.0 W); unsuitable for >100 mA regulation or surge clamping | Choose MMSZ5245B-TP only for space-constrained, low-current biasing; avoid for power regulation roles |
Compared with 1N4753A and MMSZ5245B-TP, the 1N4753APE3/TR8 delivers full 1.0 W dissipation in DO-41 with RoHS compliance and proven surge robustness-making it the only option suitable for industrial-grade 36 V reference and clamping where reliability and regulatory alignment are mandatory.

FAQ
What is the Zener voltage tolerance of the 1N4753APE3/TR8?
The 1N4753APE3/TR8 has a nominal Zener voltage of 36 V with ±5% tolerance, indicated by the "A" suffix in the part number per Microsemi's documentation. This tolerance applies at 7.0 mA test current and 25°C lead temperature. The 1N4753APE3/TR8 maintains this specification across its full operating temperature range of –65°C to +150°C, verified per JEDEC test conditions.
Does the 1N4753APE3/TR8 require dry packing before PCB assembly?
No, the 1N4753APE3/TR8 does not require dry packing. It is rated Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored indefinitely at ambient conditions without baking or desiccant packaging. This simplifies handling and eliminates pre-reflow bake steps in manufacturing, confirmed in Microsemi's 2005 REV C datasheet.
What is the maximum surge current rating for the 1N4753APE3/TR8?
The 1N4753APE3/TR8 has a maximum non-repetitive surge current rating of 1000 mA, measured using a ½-sine wave pulse of 1/120 second duration at 25°C ambient. This rating supports transient overvoltage clamping in power rails and is validated per Note 3 in the official Microsemi datasheet.
Is the 1N4753APE3/TR8 compatible with lead-free reflow profiles?
Yes, the 1N4753APE3/TR8 features RoHS-compliant annealed matte-tin plating and is rated for soldering at 260°C for 10 seconds maximum, fully compatible with standard lead-free reflow profiles. Its DO-41 plastic body meets UL94V-0 flammability requirements, ensuring reliability under thermal stress during assembly.
How does the thermal resistance of the 1N4753APE3/TR8 compare between junction-to-lead and junction-to-ambient?
The 1N4753APE3/TR8 has a junction-to-lead thermal resistance of 45°C/W (measured at 3/8″ lead length), while junction-to-ambient is 105°C/W on FR4 board with specified copper area. This means effective thermal management relies primarily on lead conduction-not PCB copper-so designers must ensure adequate lead length and thermal relief in layout to avoid exceeding 105°C junction temperature.
