Product details
Overview
1N4759E3/TR13 from Microsemi is a 1.0 W, 62 V ±5% Zener diode in DO-41 plastic package, rated for 4.0 mA test current (IZT), 125 Ω dynamic impedance (ZZT), and 5 μA reverse leakage at 47.1 V (VR). It operates from –65°C to +150°C and regulates voltage in power supply reference and overvoltage protection circuits.
For engineers reviewing the 1N4759E3/TR13 datasheet, 1N4759E3/TR13 pinout, 1N4759E3/TR13 application, or 1N4759E3/TR13 equivalent, key selection factors include its 62 V nominal Zener voltage, 1.0 W steady-state power rating at TL < 105°C, 125 Ω impedance at IZT, RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR13).
Technical Context
This axial-lead Zener diode functions as a two-terminal voltage reference device, operating in reverse breakdown with cathode band indicating polarity. Its regulation performance is specified at 4.0 mA test current and validated across –65°C to +150°C ambient and lead temperature ranges.
Thermal resistance is 45°C/W junction-to-lead (3/8″ lead length) and 105°C/W junction-to-ambient on FR4 with defined copper pad geometry. Forward voltage is ≤1.2 V at 200 mA, and it meets MIL-STD-750 Method 1020 for ESD insensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±5% at 4.0 mA - defines precise regulation point for feedback networks |
| Power Dissipation | 1.0 W at TL < 105°C - sets maximum continuous thermal load on lead-mounted layout |
| Dynamic Impedance (ZZT) | 125 Ω at IZT = 4.0 mA - determines output voltage stability under varying load current |
| Reverse Leakage (IR) | 5 μA max at VR = 47.1 V - ensures low standby current in high-impedance bias networks |
| Operating Temperature | –65°C to +150°C - supports industrial and automotive under-hood environments |
| Package | DO-41 (DO-204AL) plastic - standard axial-leaded through-hole mounting with UL94V-0 epoxy body |
| RoHS Compliance | e3 suffix - annealed matte-tin plating, lead-free, compliant with EU Directive 2011/65/EU |
Pinout & Package
DO-41 (DO-204AL) plastic package: axial-leaded, void-free thermosetting epoxy body, UL94V-0 rated, cathode indicated by colored band. Leads are tin-lead or RoHS-compliant matte-tin plated per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded end | Connected to lower-potential node; reverse-biased operation requires cathode at higher potential |
| Cathode | Banded end | Connected to regulated output or reference node; polarity must be observed to enable Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 1N47xxA series | Industry-standard footprint and electrical behavior enabling direct substitution in legacy designs |
| Moisture Sensitivity Level 1 | No dry-pack required - simplifies handling and eliminates bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Robust handling during manual and automated assembly without special ESD controls |
| Tape-and-reel packaging (TR13) | Standard EIA-296 format - compatible with high-speed pick-and-place equipment for volume production |
| Plastic P-suffix construction | Lower thermal resistance vs. glass-body variants - improves power handling in compact layouts |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Stabilizing feedback voltage in linear regulator ICs or discrete transistor-based regulators. IC Role / Device Role / Timing Role: Voltage reference element setting output voltage via resistor divider network.

Use Value: Low 5 μA leakage at 47.1 V ensures minimal error contribution in high-impedance Wheatstone bridge arms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4759A | No "e3" RoHS suffix; Sn/Pb plating; same electrical specs and DO-41 package | Not suitable for lead-free assembly processes; requires Pb-containing solder profile | Select when legacy Pb-based manufacturing or qualification requirements mandate Sn/Pb terminations |
| MMSZ5259ET1G | Surface-mount SOD-123 package; 62 V ±5%; 500 mW rating; 150 Ω ZZT at 5 mA | Lower power rating and different thermal path; requires PCB re-layout for SMT placement | Choose for space-constrained boards where through-hole mounting is impractical and 500 mW suffices |
Compared with 1N4759A and MMSZ5259ET1G, the 1N4759E3/TR13 offers full 1.0 W dissipation in a standard through-hole package with RoHS compliance, making it optimal for industrial power supplies requiring robust thermal margin and lead-free process compatibility.

FAQ
What is the Zener voltage tolerance for 1N4759E3/TR13?
The 1N4759E3/TR13 has a nominal Zener voltage of 62 V with a ±5% tolerance, as indicated by the "A" suffix in the base part number. This tolerance is measured at 4.0 mA test current and 25°C lead temperature, and applies across the full operating temperature range of –65°C to +150°C.
Does 1N4759E3/TR13 require dry packing before reflow?
No, the 1N4759E3/TR13 is moisture sensitivity level (MSL) 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ambient conditions without baking or dry packing. This eliminates pre-reflow conditioning steps in manufacturing.
What is the maximum surge current rating for 1N4759E3/TR13?
The 1N4759E3/TR13 has a maximum non-repetitive reverse surge current (ISM) of 2000 mA, measured using a ½ sine-wave pulse of 1/120 second duration at 25°C ambient. This rating supports transient overvoltage suppression in power rail protection circuits.
Can 1N4759E3/TR13 be used in surface-mount designs?
No - the 1N4759E3/TR13 uses a DO-41 axial-leaded package intended for through-hole mounting. For surface-mount equivalents, consider the SMAJ4759A or MLL4759A series, which share the same 62 V Zener voltage but use SMC and SOD-123 packages respectively.
What does the "TR13" suffix indicate in 1N4759E3/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format enables automated placement in high-volume PCB assembly and ensures consistent orientation and spacing for pick-and-place machines.
