Product details
Overview
MM5Z33VT5GF from Nexperia is a 33 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 = 2 mA and 32.34–33.66 V nominal regulation range - used for precision voltage reference and overvoltage clamping in low-power analog signal conditioning circuits.
For engineers reviewing the MM5Z33VT5GF datasheet, MM5Z33VT5GF pinout, MM5Z33VT5GF application, or MM5Z33VT5GF equivalent, this device serves as a compact, thermally efficient voltage regulator diode for space-constrained PCBs requiring stable 33 V reference under transient surge conditions and low-temperature-coefficient operation.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 33 V reference across its cathode-anode terminals, with temperature coefficient of +27.4 to +33.4 mV/K at IZ = 2 mA and junction-to-solder-point thermal resistance of 65 K/W - enabling predictable regulation in ambient temperatures from −55 °C to +150 °C.
Its ultra-small SOD523 footprint supports high-density layouts, while the 0.05 Ω differential resistance ensures minimal voltage deviation under load variation, and the 325 µA reverse current at VR = 30 V confirms sharp knee characteristics suitable for precision clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 32.34 V to 33.66 V at IZ = 2 mA - defines precise regulation window for 33 V reference design |
| Tolerance | ±2 % - enables tight voltage margin control without post-production trimming |
| Differential resistance (rdiff) | 0.05 Ω at IZ = 2 mA - ensures <10 mV output shift per 200 mA load change |
| Total power dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 PCB with 35 mm² copper - sets continuous thermal limit for board-level layout |
| Non-repetitive peak reverse power (PZSM) | 40 W for tp = 100 µs square wave - supports ESD/surge protection in transient suppression circuits |
| Reverse current (IR) | 325 µA max at VR = 30 V - confirms low leakage below regulation threshold |
| Thermal resistance (Rth(j-sp)) | 65 K/W junction-to-solder-point - allows accurate thermal modeling from die to PCB copper |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package with 2 leads, 1.25 mm × 0.85 mm body, 0.65 mm height, and cathode band marking on terminal 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C33 | Same 33 V ±5 % tolerance, SOD523 package, but higher rdiff = 90 Ω and Ptot = 350 mW | Less precise regulation under load; suited for non-critical clamping only | Select when cost priority outweighs regulation accuracy and thermal performance |
| MMSZ5260B | 33 V ±5 %, SOD-123 package (larger), rdiff = 35 Ω, Ptot = 500 mW | Higher power handling but 2× PCB area; incompatible with ultra-dense layouts | Choose when board space permits and higher continuous power is required |
Compared with BZX584-C33 and MMSZ5260B, MM5Z33VT5GF delivers superior regulation stability (±2 % vs ±5 %), lowest dynamic impedance (0.05 Ω), and smallest footprint - making it optimal for precision, space-constrained, and thermally sensitive applications.

FAQ
What is the maximum continuous forward current for MM5Z33VT5GF?
The MM5Z33VT5GF is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per Table 5, but forward conduction is not part of its functional use case - it is specified only for handling accidental polarity reversals or test conditions.
Can MM5Z33VT5GF replace a 33 V Zener in an existing SOD-123 design?
No - MM5Z33VT5GF uses SOD523 (SC-79) package with 1.25 mm × 0.85 mm outline and different pad layout than SOD-123; direct replacement requires PCB redesign and solder footprint adjustment per Figure 10 in the datasheet.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 2 mA, the temperature coefficient is +27.4 to +33.4 mV/K, resulting in ~2.7 V total drift across 100 K span - meaning regulation shifts from ~32.3 V at −40 °C to ~35.0 V at +125 °C, requiring system-level compensation if sub-1 % accuracy is needed.
Is MM5Z33VT5GF suitable for automotive applications?
No - this device is not AEC-Q200 qualified, lacks automotive-grade screening, and is explicitly designated for industrial and consumer use; Nexperia states non-automotive qualified products are unsuitable for safety-critical or automotive equipment per Section 14 legal disclaimers.
