Product details
Overview
1N4744A,113 from Nexperia is a 15 V ±5 % Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 1000 mW total power dissipation and 500 mA maximum forward current, used for precision low-voltage stabilization in linear power supplies and reference circuits.
For engineers reviewing the 1N4744A,113 datasheet, 1N4744A,113 pinout, 1N4744A,113 application, or 1N4744A,113 equivalent, key selection criteria include nominal Zener voltage (15 V), test current (17 mA), differential resistance (14 Ω), reverse leakage (≤5 µA at 11.4 V), and thermal resistance (110 K/W).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load and line conditions. It is characterized at Tj = 25 °C with 17 mA test current, delivering 15 V nominal output with ±5 % tolerance and 14 Ω dynamic impedance.
Designed for thermal equilibrium in still air with 10 mm lead length, it supports continuous operation up to +200 °C junction temperature and withstands non-repetitive peak reverse currents up to 304 mA, making it suitable for regulated biasing and overvoltage clamping in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15 V nominal, ±5 % tolerance - ensures stable reference within 14.25–15.75 V at 17 mA test current |
| Test Current Itest | 17 mA - defines operating point where VZ and dynamic impedance are specified |
| Differential Resistance rdif | 14 Ω - low impedance improves regulation against load transients |
| Reverse Current IR | ≤5 µA at 11.4 V - confirms sharp knee and low leakage below breakdown |
| Total Power Dissipation Ptot | 1000 mW - enables use in medium-power shunt regulators without forced cooling |
| Forward Voltage VF | ≤1.2 V at 200 mA - supports reliable anode-cathode conduction during fault or polarity reversal |
| Junction Temperature Range | −65 °C to +200 °C - allows deployment in industrial and automotive under-hood environments |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes shunt current path |
Key Features

Applications
| Linear Power Supply Reference | Overvoltage Clamp Circuit |
|---|---|
Use Scenario: Stabilizing unregulated DC outputs in discrete 15 V linear supplies for op-amp rails or microcontroller peripherals. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 15 V bias to series pass transistor base or error amplifier input. Use Value: Maintains output stability within ±0.75 V across line and load variations due to tight 15 V ±5 % tolerance and low 14 Ω impedance. |
Use Scenario: Protecting downstream analog inputs from transient overvoltage events exceeding 15 V. IC Role / Device Role / Timing Role: Clamping element that conducts above 15.75 V to divert surge current away from sensitive circuitry. Use Value: Limits clamping voltage to ≤15.75 V with fast response and no latch-up, leveraging 304 mA non-repetitive peak current capability. |
| Current Source Biasing | Temperature-Stable Oscillator Reference |
Use Scenario: Establishing fixed bias current for JFET or BJT-based constant-current sources in sensor signal conditioning. IC Role / Device Role / Timing Role: Voltage reference setting emitter/base voltage drop to define collector current magnitude. Use Value: Delivers <1 % current drift over −40 °C to +85 °C due to matched thermal coefficient of Zener and series resistor. |
Use Scenario: Providing stable 15 V supply to RC oscillator timing networks in low-cost clock generators. IC Role / Device Role / Timing Role: Regulated voltage source ensuring consistent charging current into timing capacitor. Use Value: Reduces frequency drift to <±0.5 % over temperature by stabilizing oscillator supply against rail variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A-T | Same electrical specs; tape-and-reel packaging (3000 pcs/reel) vs. bulk (113 = bulk) | Optimized for automated SMT placement; requires compatible feeder and reflow profile | Select when integrating into high-volume PCB assembly with pick-and-place equipment |
| BZX85C15 | 15 V ±5 %, but higher 20 Ω dynamic impedance and 1.3 W power rating in DO-41 | Higher power handling but looser regulation; suited for less critical clamping | Choose only if >1000 mW dissipation margin is required and 14 Ω impedance is not critical |
Compared with 1N4744A-T and BZX85C15, the 1N4744A,113 offers identical regulation performance in bulk form-ideal for prototyping and low-volume production-while avoiding unnecessary packaging overhead or compromised dynamic impedance.

FAQ
What is the maximum continuous power dissipation for 1N4744A,113?
The 1N4744A,113 has a maximum total power dissipation of 1000 mW at Tamb = 50 °C, derating linearly above that ambient temperature at 8.3 mW/°C based on its 110 K/W thermal resistance from junction to tie-point.
How is the cathode identified on the 1N4744A,113 package?
The cathode is marked by a single black band on the glass body of the SOD66 (DO-41) package; this banded end corresponds to Pin 1 and must be connected to the higher-potential node during Zener operation.
Can 1N4744A,113 replace 1N4744A in existing designs?
Yes-the ",113" suffix denotes bulk packaging per Nexperia's ordering convention; all electrical, thermal, and mechanical specifications-including 15 V Zener voltage, 14 Ω impedance, and DO-41 outline-are identical to the base 1N4744A part number.
What is the reverse leakage current specification at 11.4 V?
At VR = 11.4 V and Tj = 25 °C, the reverse current IR is guaranteed ≤5 µA, confirming minimal conduction well below the 15 V breakdown threshold and supporting clean turn-on behavior.
