Product details
Overview
3EZ13D5 from ON Semiconductor is a 3 W axial-lead Zener diode with nominal Zener voltage of 13 V (±5%), maximum Zener impedance of 58 Ω at 4.5 mA test current, and surge rating of 98 W for 1 ms. It operates from −65 °C to +200 °C and is used for voltage regulation and overvoltage protection in DC power supplies and reference circuits.
For engineers reviewing the 3EZ13D5 datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal derating behavior, DO−41 package dimensions, ESD robustness (Class 3, >16 kV HBM), and real-world design implications for stable voltage clamping under transient conditions.
Technical Context
The 3EZ13D5 uses a silicon-oxide passivated junction in a Surmetic 30 construction, enabling stable Zener breakdown with low leakage (≤0.25 μA at 10.4 V) and tight voltage tolerance. Its 3 W steady-state power dissipation at 75 °C lead temperature supports reliable operation in compact, non-heatsinked layouts.
Thermal performance is defined by junction-to-lead resistance (θJL), with derating curves specifying 24 mW/°C above 75 °C for 3/8″ lead length. Surge capability follows JEDEC-standard non-repetitive 1/120 s sine-wave pulses, not DC thermal limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V @ IZT = 4.5 mA - ensures ±5% regulation accuracy across production units under standard test conditions. |
| Zener Impedance (ZZT) | 58 Ω max @ IZT = 4.5 mA - defines dynamic resistance affecting regulation precision during load transients. |
| Reverse Leakage (IR) | ≤0.25 μA @ VR = 10.4 V - guarantees minimal standby current in high-impedance bias networks. |
| Surge Power Rating | 98 W @ 1 ms - enables single-event transient suppression without degradation, per JEDEC waveform standards. |
| ESD Rating | Class 3 (>16 kV HBM) - allows safe handling and board-level integration without additional ESD protection circuitry. |
| Operating Temperature | −65 °C to +200 °C - supports deployment in automotive engine compartments and industrial control enclosures. |
Pinout & Package
Package: DO−41 (Case 59−10), axial-leaded plastic, cathode indicated by polarity band. Dimensions: A = 4.10–5.20 mm (length), B = 2.00–2.70 mm (body diameter), D = 0.71–0.86 mm (lead diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side of regulated circuit; reverse-biased operation places anode at lower voltage than cathode. |
| Cathode | Zener breakdown terminal / voltage clamp output | Connected to regulated rail; clamps voltage to 13 V when reverse current exceeds knee threshold (IZK = 0.25 mA). |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Guarantees predictable clamping level without post-production trimming or selection bins. |
| Surmetic 30 silicon-oxide passivation | Provides long-term stability and low parameter drift under thermal cycling and humidity exposure. |
| Pb-free compatible packaging | Meets RoHS requirements without performance trade-offs; identical electrical specs apply to standard and Pb-free variants. |
| DO−41 footprint compatibility | Enables drop-in replacement for legacy 1 W Zeners while delivering 3× power handling in same axial form factor. |
Applications
| DC Power Supply Regulation | Overvoltage Protection Circuit |
|---|---|
Use Scenario: Stabilizing 12 V rail in automotive accessory modules where input varies from 9–16 V. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to clamp output voltage at 13 V nominal. Use Value: Maintains downstream logic supply within safe operating range despite battery voltage spikes up to 16 V. | Use Scenario: Protecting microcontroller I/O pins against ESD and load-dump transients in industrial sensor nodes. IC Role / Device Role / Timing Role: Clamping device shunting excess energy to ground during fast-rising voltage events. Use Value: Absorbs 98 W for 1 ms without failure, preventing latch-up or gate oxide damage in connected ICs. |
| Voltage Reference for Analog Circuits | Field-Serviceable Calibration Standard |
Use Scenario: Providing stable 13 V reference for ADC biasing in portable test equipment. IC Role / Device Role / Timing Role: Precision voltage source with low temperature coefficient (≈+3.5 mV/°C near 13 V) and minimal drift. Use Value: Enables <1 LSB error in 12-bit conversions over −40 °C to +85 °C ambient range. | Use Scenario: On-site calibration of multimeters and power analyzers requiring traceable 13 V reference points. IC Role / Device Role / Timing Role: Stable, hand-solderable Zener used as field-deployable voltage standard. Use Value: Delivers ±5% accuracy without oven control or active compensation, reducing calibration tool cost and complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | Same 12 V nominal Zener voltage, but ±5% tolerance and 1 W power rating (vs. 3 W for 3EZ13D5) | Limited to low-power biasing; unsuitable for surge-heavy or continuous 3 W dissipation scenarios | Select 1N4742A only when thermal budget and transient energy are strictly constrained. |
| BZX55C13 | 13 V Zener, ±5%, but rated at 500 mW and higher ZZT (≤25 Ω at 5 mA); smaller DO-35 package | Lower surge capacity (30 W typical) and reduced thermal mass limit use in high-energy clamping | Choose BZX55C13 for space-constrained PCBs where peak power remains below 0.5 W. |
Compared with 1N4742A and BZX55C13, the 3EZ13D5 delivers triple the power handling and superior surge immunity in the same axial footprint-critical for automotive and industrial systems where reliability under stress is non-negotiable.

FAQ
What is the Zener voltage tolerance of the 3EZ13D5?
The 3EZ13D5 has a guaranteed Zener voltage tolerance of ±5%, with a nominal value of 13 V and specified range of 12.35 V to 13.65 V at IZT = 4.5 mA. This tolerance is confirmed in the Electrical Characteristics table of the ON Semiconductor datasheet Rev. 4, and applies across the full operating temperature range.
Can the 3EZ13D5 be used in place of a 1 W Zener diode?
Yes, the 3EZ13D5 can replace 1 W Zeners like the 1N4742A in the same DO−41 footprint, but only if thermal management accommodates its higher 3 W steady-state dissipation. Its 3 W rating requires proper lead length (3/8″ minimum) and ambient temperature control-unlike 1 W devices, it must be derated above 75 °C at 24 mW/°C.
What is the maximum reverse leakage current for the 3EZ13D5?
The maximum reverse leakage current for the 3EZ13D5 is 0.25 μA at VR = 10.4 V (80% of nominal VZ), as specified in the Electrical Characteristics table. This low leakage supports high-impedance bias networks and precision reference applications where standby current must remain sub-microamp.
Does the 3EZ13D5 meet RoHS requirements?
Yes, the 3EZ13D5 is available in Pb-free packaging compliant with RoHS Directive 2011/65/EU. ON Semiconductor confirms identical electrical specifications apply to both standard and Pb-free versions, and Pb-free orderable part numbers are published on their official website.
How is the surge rating of the 3EZ13D5 defined?
The 3EZ13D5 has a non-repetitive surge rating of 98 W for 1 ms, based on a JEDEC-standard 1/120 s sine-wave or equivalent half-sine pulse. This rating reflects actual device capability-not thermal calculation-and is validated in Figure 3 of the datasheet; exceeding it risks irreversible junction degradation.
