Product details
Overview
MM3Z62VT1G from onsemi is a 62 V ±5% Zener voltage regulator diode in SOD−323 package, rated for 300 mW steady-state power dissipation at 25°C, with 215 Ω maximum Zener impedance at 2 mA test current and 0.05 μA reverse leakage at 43.4 V. It serves as precision voltage reference and overvoltage clamp in space-constrained portable electronics.
For engineers reviewing the MM3Z62VT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 62 V nominal Zener voltage tolerance, low 35 pF capacitance at 0 V bias, Class 3 ESD rating (>16 kV HBM), thermal resistance of 416°C/W, and AEC−Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its 62 V nominal Zener voltage (min 58 V, max 66 V) is specified at 2 mA test current, with temperature coefficient of +0.4 mV/°C and junction-to-ambient thermal resistance of 416°C/W.
The device features low dynamic impedance (215 Ω max at IZT = 2 mA), tight leakage control (≤0.05 μA at VR = 43.4 V), and ultra-low capacitance (35 pF at 0 V, 1 MHz), enabling use in high-frequency voltage clamping and precision reference circuits where parasitic effects must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 58 V min / 62 V nom / 66 V max @ IZT = 2 mA - defines clamping threshold with ±5% tolerance for reliable overvoltage protection. |
| Power Dissipation (PD) | 300 mW @ TA = 25°C - supports continuous regulation in compact PCB layouts without forced cooling. |
| Zener Impedance (ZZT) | 215 Ω max @ IZT = 2 mA - ensures minimal voltage deviation under dynamic load transients. |
| Reverse Leakage (IR) | ≤0.05 μA @ VR = 43.4 V - guarantees negligible standby current in battery-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B62,115 (Nexperia) | Same 62 V nominal Zener, but 200 mW power rating and 400 Ω ZZT; SOD-323 package. | Limited to lower-energy transients; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification and higher surge margin. |
| SZMM3Z62VT1G (onsemi) | Identical electrical specs and package; adds SZ prefix denoting AEC-Q101 compliance and PPAP capability. | Required for Tier-1 automotive BOMs mandating traceable process controls. | Choose for production programs requiring automotive-grade documentation and change control. |

FAQ
What is the Zener voltage tolerance of MM3Z62VT1G?
The MM3Z62VT1G has a nominal Zener voltage of 62 V with a tolerance of ±5%, meaning the actual breakdown voltage falls between 58 V and 66 V when tested at 2 mA. This tolerance is guaranteed across the full operating temperature range of −65°C to +150°C and is verified per onsemi's production test flow.
Is MM3Z62VT1G suitable for automotive applications?
Yes, MM3Z62VT1G is AEC−Q101 qualified and PPAP capable, making it suitable for automotive applications such as infotainment power rail clamping and sensor interface protection. Its SOD−323 package, Class 3 ESD rating, and −65°C to +150°C junction temperature range meet stringent automotive reliability requirements.
What is the maximum Zener impedance of MM3Z62VT1G and at what test condition?
The maximum Zener impedance (ZZT) of MM3Z62VT1G is 215 Ω, measured at a Zener test current (IZT) of 2 mA and ambient temperature of 25°C. This value reflects dynamic resistance under small-signal AC conditions and directly impacts voltage regulation stability during load transients.
Does MM3Z62VT1G have lead-free construction?
Yes, MM3Z62VT1G is a Pb−free device with Sn-only plating on its leads, compliant with RoHS Directive 2011/65/EU. The package uses void-free transfer-molded plastic and meets UL 94 V−0 flammability rating, supporting environmentally conscious manufacturing and end-of-life compliance.
How does the capacitance of MM3Z62VT1G affect high-speed signal lines?
MM3Z62VT1G exhibits 35 pF typical capacitance at 0 V bias and 1 MHz, which minimizes loading on high-speed signal paths such as HDMI or USB differential pairs. This low capacitance prevents signal rise/fall time degradation and maintains eye diagram integrity in applications where the diode is used for ESD clamping adjacent to data lines.
