Product details
Overview
MM3Z15VT1GX from Nexperia is a 15 V ±5 % tolerance Zener diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, designed for precision voltage regulation in low-power analog and digital supply rails.
For engineers reviewing the MM3Z15VT1GX datasheet, MM3Z15VT1GX pinout, MM3Z15VT1GX application, or MM3Z15VT1GX equivalent, this device serves as a stable shunt reference in power management, overvoltage protection, and signal-level clamping circuits where compact size, tight voltage tolerance, and low differential resistance are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 15 V at IZ = 5 mA, exhibiting a differential resistance of ≤ 0.05 Ω and a temperature coefficient of +9.2 to +13.0 mV/K across its operating current range. Its low capacitance (99 pF at f = 1 MHz, VR = 0 V) supports high-frequency stability in feedback and clamping paths.
The device is characterized for junction temperatures up to 150 °C and ambient operation from −55 °C to +150 °C, with thermal resistance from junction to ambient of 415 K/W on standard FR4 PCB. It meets IEC 60134 absolute maximum ratings, including 200 mA forward current and 40 W surge capability under defined pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.84 V to 15.52 V at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Differential Resistance (rdiff) | ≤ 0.05 Ω - ensures minimal voltage shift under load current variation, critical for regulation accuracy |
| Temperature Coefficient (SZ) | +9.2 to +13.0 mV/K - quantifies voltage drift per degree Celsius rise, enabling thermal error budgeting |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets continuous DC power limit for thermal design on standard PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W (tp = 100 µs, square wave) - supports transient overvoltage suppression without failure |
| Reverse Current (IR) | ≤ 80 µA at VR = 11.0 V - confirms low leakage below knee voltage, essential for standby power integrity |
| Forward Voltage (VF) | 1.1 V at IF = 100 mA - specifies conduction loss when used in forward-biased protection or logic interface roles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B15 | Same 15 V nominal, ±5 % tolerance, but SOD323 package with 250 mW Ptot rating (vs. 300 mW) | Limited continuous power margin in thermally constrained layouts; identical clamping performance | Select when legacy BOM alignment or dual-sourcing with tighter thermal derating is required |
| MMBZ5245B | 15 V nominal, ±5 %, but SOT-23 package (larger footprint) and higher rdiff (15 Ω vs. ≤0.05 Ω) | Higher regulation error under dynamic load; less suitable for precision references | Prefer for designs already using SOT-23 footprints or where board space allows larger package |
Compared with BZX384-B15 and MMBZ5245B, MM3Z15VT1GX delivers superior regulation stability due to its ultra-low differential resistance and higher continuous power rating, making it optimal for space-constrained, high-accuracy shunt reference applications.

FAQ
What is the maximum continuous reverse current for stable Zener operation?
The MM3Z15VT1GX is specified for stable regulation at IZ = 5 mA, with maximum recommended continuous reverse current limited by thermal constraints: at 25 °C ambient, 300 mW power dissipation corresponds to ~20 mA (15 V × 20 mA = 300 mW). Operation above this requires derating per Rth(j-a) = 415 K/W to avoid exceeding 150 °C junction temperature.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a temperature coefficient of +9.2 to +13.0 mV/K, the Zener voltage increases by approximately 1.25 V to 1.8 V across a 125 K temperature span. For a 15 V nominal device, this yields a worst-case drift of ±6.25 % over full range-designers must include this in system-level error budgets for precision references.
Can MM3Z15VT1GX be used in forward-bias applications like LED biasing?
Yes: its forward voltage is 1.1 V at 100 mA, with 200 mA absolute maximum forward current. This makes it suitable for low-current forward applications such as optocoupler LED biasing or logic-level translation, provided current-limiting resistors are sized to stay within IF limits and thermal boundaries.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes-the SOD323 footprint complies with JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles. Nexperia provides validated reflow land patterns (Fig. 12) with 0.5 mm solder paste openings and 0.6 mm solder lands, ensuring reliable joint formation without tombstoning or voiding.
