Product details
Overview
SZMM5Z7V5T5GF from Nexperia is a Zener voltage regulator diode in SOD523 (SC-79) package, designed for precision low-voltage regulation and reference functions in space-constrained PCBs. It delivers a nominal 7.5 V Zener voltage at 5 mA, with ±2 % tolerance, 1.0 Ω typical differential resistance, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the SZMM5Z7V5T5GF datasheet, SZMM5Z7V5T5GF pinout, SZMM5Z7V5T5GF application, or SZMM5Z7V5T5GF equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (Rth(j-sp) = 65 K/W), surge capability (40 W non-repetitive peak reverse power), and SOD523 footprint compatibility in high-density automotive and industrial power rails.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across variable load currents by conducting reverse current above its specified Zener breakdown threshold. Its low 1.0 Ω differential resistance ensures minimal voltage deviation under dynamic load changes.
Thermally optimized for surface-mount use on FR4 PCBs with ~35 mm² copper area at the cathode tab, it achieves Rth(j-a) = 350 K/W and Rth(j-sp) = 65 K/W - enabling reliable operation up to 150 °C junction temperature while supporting transient surge handling per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.35 V to 7.65 V at IZ = 5 mA - defines tight regulation window for 7.5 V reference applications |
| Differential Resistance (rdiff) | 1.0 Ω max at IZ = 5 mA - ensures <10 mV output shift per 10 mA load change |
| Temperature Coefficient (SZ) | +2.5 mV/K to +5.3 mV/K - enables predictable drift compensation in temperature-varying circuits |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports ESD/surge protection in automotive transients (ISO 7637-2 Pulse 1/2) |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets continuous DC regulation limit on standard FR4 layout |
| Reverse Current (IR) | ≤10 µA at VR = 5.0 V - guarantees low leakage in standby power domains |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - defines forward conduction loss during polarity-reversal fault conditions |
Pinout & Package
SZMM5Z7V5T5GF uses the SOD523 (SC-79) ultra-small flat-lead surface-mount package: 1.25 mm × 0.85 mm body, 0.65 mm height, cathode marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; primary heat path to PCB copper |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
| ±2 % Zener voltage tolerance | Reduces need for post-assembly trimming in 7.5 V reference designs for sensor biasing and ADC references |
| Low 1.0 Ω differential resistance | Maintains regulation stability across 1–10 mA load variations in battery-powered microcontroller supply monitors |
| Ultra-compact SOD523 footprint | Enables placement adjacent to IC power pins without compromising routing density in ADAS domain controllers |
| 65 K/W junction-to-solder-point thermal resistance | Supports localized thermal management via direct cathode copper pour, critical for sustained 200 mA surge events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C7V5 | Same 7.5 V nominal, ±2 %, but SOD323 package (larger); Rth(j-a) = 450 K/W; no AEC-Q101 qualification | Limited to commercial-grade consumer products; unsuitable for under-hood automotive use | Select only when board layout allows larger footprint and automotive qualification is not required |
| MMSZ5231BT1G | 7.5 V nominal, ±5 % tolerance; SOD-123 package; Ptot = 500 mW; no surge rating specified | Higher power dissipation but looser voltage accuracy; lacks defined transient robustness | Prefer for general-purpose regulation where cost outweighs precision and surge immunity |
Compared with BZX584C7V5 and MMSZ5231BT1G, SZMM5Z7V5T5GF uniquely combines automotive qualification, ultra-small SOD523 size, tight ±2 % tolerance, and documented 40 W surge capability - making it the sole choice for space-constrained, safety-critical 7.5 V reference nodes.

FAQ
What is the maximum continuous reverse current this Zener can handle at 7.5 V?
The device is rated for total power dissipation of 300 mW at 25 °C ambient. At 7.5 V, this corresponds to a maximum continuous reverse current of 40 mA (300 mW ÷ 7.5 V). Derating applies above 25 °C per the thermal resistance curve in the datasheet.
Can SZMM5Z7V5T5GF be used as a substitute for a 7.5 V bandgap reference in ADC applications?
Yes - its ±2 % tolerance, low 1.0 Ω differential resistance, and +2.5 to +5.3 mV/K temperature coefficient allow stable 7.5 V reference generation. However, unlike bandgaps, it exhibits inherent tempco drift; compensation circuitry may be needed for <0.1 % total error over temperature.
How does the SOD523 package affect thermal performance compared to SOD-123?
The SOD523's smaller size reduces thermal mass but improves solder-point thermal coupling: Rth(j-sp) = 65 K/W versus ~120 K/W for typical SOD-123 parts. This enables faster transient heat transfer to PCB copper, critical for surviving 40 W surge pulses without junction overheating.
Is the cathode marking consistent across all SZMM5Z series variants?
Yes - all SZMM5ZxxxT5G devices use identical SOD523 packaging with a single cathode bar marking on the top surface, aligned with Pin 1 per JEDEC MO-203-AB. The marking code 'E3' specifically identifies the 7.5 V variant, per Table 4 in the datasheet.
