Product details
Overview
MM5Z5V6T5GF from Nexperia is a 5.6 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 1.0 Ω typical differential resistance at IZ = 5 mA and −2.0 mV/K temperature coefficient at IZ = 5 mA, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the MM5Z5V6T5GF datasheet, MM5Z5V6T5GF pinout, MM5Z5V6T5GF application, or MM5Z5V6T5GF equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-sp) = 65 K/W), cathode-anode polarity marking, junction temperature limit (150 °C), and SOD523 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 5.6 V regulation across load and line variations. Its low 1.0 Ω differential resistance ensures minimal voltage deviation under dynamic current changes up to 200 mA forward/5 mA Zener test current.
The device features a −2.0 mV/K temperature coefficient near zero TC crossing, optimized for stable reference performance between 25 °C and 150 °C ambient. Thermal resistance from junction to solder point is 65 K/W, enabling reliable operation on FR4 PCBs with ~35 mm² copper area at the cathode tab.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.49 V to 5.71 V at IZ = 5 mA - defines tight 5.6 V nominal regulation window for precision biasing |
| Differential Resistance rdiff | 1.0 Ω max at IZ = 5 mA - ensures <10 mV output shift per 10 mA load change |
| Temperature Coefficient SZ | −2.0 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive references |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C - supports continuous operation in space-constrained SOD523 footprints |
| Non-repetitive Peak Reverse Power | 40 W (tp = 100 µs, square wave) - provides transient surge immunity in ESD-coupled signal paths |
| Reverse Current IR | 40 µA max at VR = 3.5 V - guarantees low leakage in standby-biased voltage clamp configurations |
| Junction-to-Solder-Point Rth(j-sp) | 65 K/W - allows direct thermal coupling to PCB copper for sustained 300 mW dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V6 | Same 5.6 V ±5 % tolerance, 300 mW rating, but SOD-323 package (larger footprint, higher Rth(j-a) = 400 K/W) | Less suitable for ultra-dense layouts; requires larger thermal pad for equivalent power handling | Select when legacy SOD-323 footprint compatibility is required over size optimization |
| MMSZ5232BT1G | 5.6 V ±5 %, 500 mW rating, SOD-123 package, higher rdiff = 10 Ω, wider TC = ±3.5 mV/K | Higher power capability but poorer regulation stability and thermal response | Prefer for higher-current clamping where 500 mW margin outweighs precision needs |
Compared with BZX584-C5V6 and MMSZ5232BT1G, MM5Z5V6T5GF delivers tighter voltage tolerance, lower differential resistance, and superior thermal coupling in the smallest available footprint-making it optimal for space-constrained, high-stability reference and clamp functions.

FAQ
What is the maximum continuous Zener current for MM5Z5V6T5GF at 25 °C ambient?
The device supports up to 53.6 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 300 mW and VZ = 5.6 V. Derating is required above 25 °C per the Rth(j-a) = 350 K/W curve; at 70 °C ambient, max continuous IZ drops to ~32 mA to maintain Tj ≤ 150 °C.
How is cathode polarity identified on the MM5Z5V6T5GF package?
The cathode is marked by a visible bar on the top surface of the SOD523 package, aligned with terminal 1 per the official Nexperia pinning diagram. This bar corresponds to the cathode (K) lead, while the unmarked end is the anode (A); orientation is confirmed in Figure 9 of the datasheet and matches standard SC-79 marking conventions.
Can MM5Z5V6T5GF be used in place of a 5.1 V Zener diode?
No-it is not a drop-in replacement for 5.1 V Zeners due to its specified 5.49 V to 5.71 V Zener voltage range. Substituting it for a 5.1 V part would raise the regulation threshold by ≥390 mV, potentially causing functional failure in circuits relying on precise 5.1 V clamping or biasing, such as USB 5 V bus monitoring or comparator reference inputs.
What reflow profile is recommended for MM5Z5V6T5GF soldering?
Nexperia specifies a standard lead-free reflow profile with peak temperature of 260 °C for ≤10 seconds, preheat ramp rate ≤3 °C/s, and time above 217 °C of 60–150 seconds. The recommended footprint (Figure 10) uses 0.5 mm pad width, 1.4 mm pad length, and 0.4 mm solder mask opening to ensure reliable joint formation without tombstoning in SOD523 geometry.
