Product details
Overview
MM5Z15VT5GF from Nexperia is a 15 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 0.05 Ω differential resistance at IZ = 10.5 mA and 9.2–13.0 mV/K temperature coefficient. It serves as a precision voltage reference or shunt regulator in low-power analog signal conditioning and power rail stabilization circuits.
For engineers reviewing the MM5Z15VT5GF datasheet, MM5Z15VT5GF pinout, MM5Z15VT5GF application, or MM5Z15VT5GF equivalent, this device is selected for stable 15 V regulation under low-current bias (IZ = 10.5 mA), tight tolerance requirements, and ultra-small PCB footprint constraints in portable and space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 15 V reference across its cathode-anode terminals. Its low 0.05 Ω dynamic resistance ensures minimal voltage deviation under load current variations up to 10.5 mA, while the 9.2–13.0 mV/K temperature coefficient defines predictable drift over −55 °C to +150 °C ambient range.
The device complies with IEC 60134 absolute maximum ratings, supports 200 mA forward current capability, and achieves 65 K/W junction-to-solder-point thermal resistance when mounted on FR4 with 35 mm² copper area - enabling reliable thermal performance in compact layouts without heatsinking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C15 | Same 15 V nominal, ±2 %, but SOD323 package (1.7 × 1.3 mm); 500 mW Ptot; rdiff = 0.15 Ω | Higher power handling but 2.5× larger footprint; less suitable for ultra-dense layouts | Select when higher continuous power margin is required and board space permits |
| MMSZ5245B | 15 V nominal, ±5 % tolerance; SOD123 package; 500 mW Ptot; rdiff = 17 Ω | Loose tolerance and high rdiff limit use to non-critical biasing, not precision references | Select only for cost-sensitive, non-precision applications where size is secondary |
Compared with BZX584C15 and MMSZ5245B, MM5Z15VT5GF delivers superior voltage accuracy and dynamic regulation stability in the smallest available footprint - making it optimal for space-constrained, high-precision analog designs where thermal and electrical performance must coexist.

FAQ
What is the maximum continuous reverse current for stable 15 V regulation?
The MM5Z15VT5GF maintains stable 15 V regulation at IZ = 10.5 mA, with a maximum recommended continuous reverse current of 100 mA to stay within its 300 mW power limit at 25 °C ambient. Exceeding this requires thermal derating per the 350 K/W junction-to-ambient resistance specification.
Can MM5Z15VT5GF replace a 1N4744A in existing designs?
No - the 1N4744A is a through-hole DO-41 device rated for 1 W, while MM5Z15VT5GF is an SMD SOD523 part rated for 300 mW. Direct replacement requires verifying thermal design, PCB layout compatibility, and power budget; the smaller package cannot dissipate equivalent energy without board-level thermal enhancements.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a specified SZ of 9.2–13.0 mV/K, the MM5Z15VT5GF exhibits approximately ±50 mV total drift over a 125 K temperature span - translating to ±0.33 % of 15 V. This is acceptable for non-critical references but requires compensation in metrology-grade applications.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes - the MM5Z15VT5GF's SOD523 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. The recommended footprint (Fig. 10 in datasheet) uses 0.5 mm pad width and 0.4 mm solder mask clearance to ensure reliable joint formation without tombstoning.
