Product details
Overview
3EZ13D5G from ON Semiconductor is a 3 W, 13 V ±5% Zener voltage regulator diode in DO-41 (Case 59) axial plastic package, featuring 58 Ω maximum Zener impedance at 4.5 mA test current, 1.54 μA reverse leakage at 9.9 V, and 98 W non-repetitive surge rating for transient overvoltage clamping in power supply feedback paths.
For engineers reviewing the 3EZ13D5G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal derating behavior, Pb-free packaging compliance, and direct replacement guidance for industrial DC-DC regulation and voltage reference designs.
Technical Context
This device operates as a precision shunt voltage regulator with guaranteed Zener voltage of 12.35–13.65 V at 4.5 mA (IZT), and exhibits low dynamic impedance (58 Ω) to maintain stable regulation under varying load conditions. Its silicon-oxide passivated junction ensures robust ESD immunity (>16 kV HBM) and long-term reliability across -65°C to +200°C operating range.
The 3EZ13D5G is rated for 3 W steady-state dissipation at 75°C lead temperature with 24 mW/°C derating above that point, and supports surge handling up to 98 W for 1 ms pulses - critical for protecting downstream circuitry against line transients in AC/DC adapters and motor drive snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V @ 4.5 mA - defines regulated output voltage tolerance band for feedback loop design |
| Zener Impedance (ZZT) | 58 Ω max @ IZT - determines regulation error under load current variation |
| Reverse Leakage (IR) | 1.54 μA max @ 9.9 V - limits quiescent current loss in high-impedance bias networks |
| Surge Rating | 98 W @ 1 ms - enables transient suppression without device failure in unregulated input stages |
| Power Dissipation | 3 W @ TL = 75°C - sets thermal design boundary for PCB trace width and heatsinking |
| ESD Rating | Class 3 (>16 kV HBM) - ensures robustness during automated assembly and field handling |
| Package | DO-41 (Case 59), axial lead, Pb-free - compatible with standard through-hole reflow and wave soldering |
Pinout & Package
DO-41 (Case 59) axial-leaded plastic package with cathode indicated by color band; leads are corrosion-resistant and readily solderable; maximum soldering temperature 260°C at 1/16″ from case for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for Zener breakdown | Connected to lower-potential side of regulated circuit; forms return path for Zener current |

Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Tight regulation window (12.35–13.65 V) reduces need for external trimming in feedback networks |

Applications
| Switch-Mode Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|

IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 13 V threshold for TL431-compatible control IC biasing. Use Value: Maintains ±1.5% output accuracy across line/load variations due to tight VZ tolerance and low ZZT. |

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 | 12 V nominal, ±5%, 1 W rating, DO-41, higher ZZT (20 Ω @ 21 mA) | Limited to lower-power regulation; insufficient surge margin for industrial transients | Select when thermal budget restricts to ≤1 W dissipation and surge risk is low |
| BZX55C13 | 13 V nominal, ±5%, 500 mW rating, DO-35, ZZT = 25 Ω @ 5 mA | Lower power handling requires series resistor derating; unsuitable for 3 W continuous use | Prefer for space-constrained PCBs where 0.5 W regulation suffices and lead pitch allows DO-35 |
Compared with 1N4742A and BZX55C13, the 3EZ13D5G delivers triple the power rating and 2× higher surge resilience while maintaining identical ±5% tolerance and DO-41 compatibility - making it the optimal choice for ruggedized 12–13 V reference and clamping in harsh-environment power systems.

FAQ
What is the Zener voltage tolerance of the 3EZ13D5G?
The 3EZ13D5G has a Zener voltage tolerance of ±5%, with a specified range of 12.35 V to 13.65 V at 4.5 mA test current (IZT). This tolerance is guaranteed per ON Semiconductor's datasheet Rev. 0 (August 2007) and applies to all units marked "3EZ13D" with "5" suffix indicating the 5% grade. The 3EZ13D5G maintains this specification across its full operating temperature range.
Can the 3EZ13D5G replace a 1N4742A in a 12 V regulator circuit?
The 3EZ13D5G is not a direct functional replacement for the 1N4742A due to its higher nominal Zener voltage (13 V vs. 12 V) and higher power rating (3 W vs. 1 W). While both share DO-41 packaging, substituting the 3EZ13D5G would raise the regulated voltage by ~1 V and require verification of thermal margin and feedback loop stability. The 3EZ13D5G is best applied where 13 V regulation and 3 W dissipation are explicitly required.
What is the maximum non-repetitive surge power the 3EZ13D5G can withstand?
The 3EZ13D5G is rated for 98 W non-repetitive surge power at 1 ms pulse width, per JEDEC-standard 1/2 sine wave testing. This value is confirmed in the "Maximum Surge Power" curve (Figure 3) of the official ON Semiconductor datasheet. Exceeding this limit risks irreversible junction damage, even if average power remains within 3 W limits.
Is the 3EZ13D5G RoHS-compliant and lead-free?
Yes, the "G" suffix in 3EZ13D5G explicitly denotes a Pb-free package per ON Semiconductor's Pb-Free strategy. The device complies with EU RoHS Directive 2011/65/EU and uses void-free, transfer-molded thermosetting plastic encapsulation. Soldering is qualified up to 260°C for 10 seconds at 1/16″ from the case body.
How does the 3EZ13D5G perform at elevated temperatures?
The 3EZ13D5G is rated for operation from -65°C to +200°C junction temperature. Its Zener voltage exhibits a positive temperature coefficient typical of 13 V devices (per Figure 8), resulting in ~+0.01%/°C drift above 25°C. Power dissipation must be derated linearly above 75°C lead temperature at 24 mW/°C to prevent thermal runaway - a requirement validated in Figure 1 of the datasheet.
