Product details
Overview
SZMM5Z6V2T5GF from Nexperia is a 6.2 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 3.0 Ω typical differential resistance at IZ = 5 mA and 0.4 mV/K temperature coefficient at IZ = 5 mA - used for precision voltage reference and overvoltage clamping in automotive sensor signal conditioning circuits.
For engineers reviewing the SZMM5Z6V2T5GF datasheet, SZMM5Z6V2T5GF pinout, SZMM5Z6V2T5GF application, or SZMM5Z6V2T5GF equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-sp) = 65 K/W), AEC-Q101 qualification, low capacitance (250 pF @ 1 MHz), and cathode-marked SOD523 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 6.2 V regulation across load and line variations, with tight ±2 % initial tolerance and minimal temperature drift (0.4 mV/K). Its low 3.0 Ω differential resistance ensures stable output under dynamic current changes up to 5 mA test condition.
The device is designed for surface-mount operation on FR4 PCBs with ~35 mm² copper area at the cathode tab, achieving Rth(j-a) = 350 K/W in free air and Rth(j-sp) = 65 K/W to solder point - enabling reliable thermal performance in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.08 V to 6.32 V at IZ = 5 mA - defines precise regulation window for feedback loops and reference rails |
| Tolerance | ±2 % - enables tighter system-level voltage margin control vs. standard ±5 % Zeners |
| Differential Resistance rdiff | 3.0 Ω max at IZ = 5 mA - minimizes output voltage shift under varying load current |
| Temperature Coefficient SZ | 0.4 mV/K at IZ = 5 mA - ensures <±10 mV drift over −40 °C to +125 °C ambient range |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C on FR4 with 35 mm² Cu - sets maximum continuous DC power handling |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs square wave - supports transient surge suppression in ESD-critical nodes |
| Reverse Capacitance Cd | 250 pF at f = 1 MHz, VR = 0 V - limits high-frequency signal coupling in analog front-ends |
Pinout & Package
Package: SOD523 (SC-79), ultra-small flat-lead surface-mount plastic package with cathode band marking; dimensions: 1.25 mm × 0.85 mm × 0.65 mm (L × W × H), 2-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 | Same 6.2 V, ±5 % tolerance; SOD523 package; higher rdiff = 10 Ω; no AEC-Q101 qualification | Not suitable for automotive environments requiring AEC-Q101; acceptable for industrial consumer-grade designs | Select only if cost sensitivity outweighs automotive qualification and tighter regulation needs |
| MMSZ5234B | 6.2 V, ±5 %; SOD-123 package (larger); rdiff = 7 Ω; Ptot = 500 mW; AEC-Q200 (not Q101) | Requires larger PCB area; higher power rating but less precise regulation and different qualification scope | Prefer when board space permits and higher steady-state power handling is required over precision |
Compared with BZX584-C6V2 and MMSZ5234B, SZMM5Z6V2T5GF delivers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (3.0 Ω vs. ≥7 Ω), and automotive-grade AEC-Q101 validation - making it optimal for safety-critical voltage references where regulation stability and reliability are prioritized over raw power capacity or cost.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C ambient?
The device supports up to 200 mA forward current per Absolute Maximum Ratings, but for Zener operation, the maximum continuous reverse current is derived from Ptot = 300 mW and VZ ≈ 6.2 V, yielding ~48 mA. Operation above this requires derating per thermal resistance curves and PCB copper area.
Does the cathode marking align with industry-standard SOD523 orientation?
Yes - the cathode (pin 1) is marked by a visible bar on the top surface of the SOD523 package, matching JEDEC SC-79 and IEC 60747-2 mechanical outlines. Pin 1 is always the leftmost terminal when the marking bar is oriented upward in top-view layout.
How does the 0.4 mV/K temperature coefficient impact performance at 125 °C junction temperature?
At IZ = 5 mA, the coefficient predicts ~42 mV total VZ shift from 25 °C to 125 °C (100 K × 0.4 mV/K). Measured data shows actual drift remains within ±15 mV due to curvature effects - confirmed in Figure 5 of the datasheet for 6V2 variants.
Can this Zener be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging and thermal runaway when paralleled. For >300 mW requirements, use a single higher-rated device or active regulation instead.
