Product details
Overview
MM3Z5V1T1GX from Nexperia is a 5.1 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, used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the MM3Z5V1T1GX datasheet, MM3Z5V1T1GX pinout, MM3Z5V1T1GX application, or MM3Z5V1T1GX equivalent, this device serves as a compact, thermally efficient voltage reference with low differential resistance (2.0 Ω at IZ = 5 mA), stable temperature coefficient (−2.7 mV/K), and verified performance across −55 °C to +150 °C ambient range.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 4.84 V to 5.37 V at 5 mA test current, exhibiting low dynamic impedance (2.0 Ω) and tight tolerance (±5 %). Its thermal resistance from junction to ambient is 415 K/W on FR4 PCB, enabling reliable operation under pulsed surge conditions up to 40 W (100 µs square wave).
The device features a cathode-anode two-terminal configuration with marking bar indicating cathode, optimized for space-constrained PCB layouts. Its capacitance is 300 pF at 0 V reverse bias (f = 1 MHz), supporting stable DC reference generation without high-frequency coupling concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.84 V to 5.37 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference rails |
| Tolerance | ±5 % - ensures predictable voltage accuracy across production lots without calibration |
| Differential Resistance (rdiff) | 2.0 Ω at IZ = 5 mA - minimizes output voltage shift under load variation |
| Temperature Coefficient (SZ) | −2.7 mV/K - enables stable reference over industrial temperature range (−55 °C to +150 °C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V1,115 (Nexperia) | Same 5.1 V rating and ±5 % tolerance, but in smaller SOD323 variant with tighter rdiff (1.5 Ω) and lower Ptot (250 mW) | Lower power handling limits use in higher-current reference paths | Select when board space is critical and average power remains ≤250 mW |
| 1N4733A (ON Semiconductor) | 5.1 V ±5 %, but in DO-35 through-hole package with higher Ptot (1 W) and rdiff (17 Ω) | Not suitable for SMT-only designs; higher impedance degrades regulation under load | Choose only for legacy through-hole prototyping or high-power linear regulator feedback |
Compared with BZX384-B5V1,115, MM3Z5V1T1GX offers higher power margin (300 mW vs. 250 mW); compared with 1N4733A, it delivers superior dynamic regulation (2.0 Ω vs. 17 Ω) in miniaturized SMT layouts.

FAQ
What is the maximum continuous forward current for MM3Z5V1T1GX?
The MM3Z5V1T1GX is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per datasheet limiting values. However, forward conduction is not its functional mode-forward voltage is specified at 1.1 V (IF = 100 mA) solely for characterization, not for sustained use.
Can MM3Z5V1T1GX be used in place of a 5 V LDO regulator?
No-it functions only as a shunt regulator, requiring an external current-limiting resistor and unable to source load current. Unlike an LDO, it cannot maintain regulation under variable load without significant power loss in the series resistor and lacks current-limiting or thermal shutdown features.
How does the −2.7 mV/K temperature coefficient affect long-term stability?
This negative coefficient means output voltage decreases by 2.7 mV per Kelvin rise in junction temperature. Over a 100 °C rise (e.g., from 25 °C to 125 °C), VZ drops ~270 mV-within its ±5 % band (±255 mV)-so system-level drift remains bounded and predictable for compensated designs.
Is the SOD323 package compatible with standard reflow profiles?
Yes-the SOD323 footprint matches IPC-7351B standards. Nexperia specifies reflow soldering with peak temperature ≤ 260 °C, 60-second duration above 217 °C, and ramp rates within JEDEC J-STD-020 limits; no special process adjustments are required for volume manufacturing.
