Product details
Overview
HZM6.2Z4MFATL-E from Renesas Electronics is a silicon planar Zener diode array with four monolithic devices in a single MPAK-5 package, designed for surge absorption and ESD protection on signal lines. It delivers 6.2 V nominal Zener voltage (5.90–6.50 V at 5 mA), 4.0 pF typical capacitance, 60 Ω dynamic resistance, and 8 kV ESD capability per IEC 61000-4-2 (150 pF/330 Ω). It is used in high-density interface protection for USB, HDMI, and industrial I/O.
For engineers reviewing the HZM6.2Z4MFATL-E datasheet, HZM6.2Z4MFATL-E pinout, HZM6.2Z4MFATL-E application, or HZM6.2Z4MFATL-E equivalent, key selection criteria include low-capacitance ESD clamping, multi-device integration in one package, surge power handling up to 100 W (nonrepetitive, 10 µs), and compatibility with automated SMT assembly on dense PCB layouts.
Technical Context
HZM6.2Z4MFATL-E integrates four identical Zener diodes sharing a common anode (Pin 4) and individual cathodes (Pins 1, 2, 3, 5), enabling independent clamping of four signal lines. Each device operates as a low-leakage (≤3 µA at 5.5 V), low-capacitance (4.0–4.5 pF) transient voltage suppressor with defined Zener knee behavior at 5 mA test current.
The device supports nonrepetitive surge reverse power up to 100 W for 10 µs pulses and maintains stable junction temperature up to 150°C. Its MPAK-5 package uses copper leadframe construction for thermal efficiency and is rated for storage from −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DBVR | Quad 5.5 V ESD diode array with 0.5 pF capacitance; uses silicon-germanium process and integrated RC filters. | Optimized for ultra-high-speed interfaces (>1 Gbps); lacks surge power rating beyond ESD pulses. | Select when signal bandwidth >1 GHz is required and surge energy is limited to ESD-only events. |
| SZ1.5SMC6.8AT3G | Single-channel 6.8 V TVS diode in SMC package; 1500 W peak pulse power, 100 pF capacitance. | Designed for bulk power-line surge suppression-not suitable for high-speed signal lines due to high capacitance. | Choose only for low-frequency power rail clamping where speed and capacitance are not constraints. |
Compared with TPD4E05U06DBVR and SZ1.5SMC6.8AT3G, HZM6.2Z4MFATL-E uniquely balances moderate-speed signal integrity (4 pF), quad-channel integration, and measurable nonrepetitive surge power handling (100 W), making it optimal for mid-bandwidth industrial and consumer interface protection where both ESD and cable-discharge events occur.

FAQ
What is the Zener voltage tolerance of HZM6.2Z4MFATL-E at 5 mA test current?
The HZM6.2Z4MFATL-E has a guaranteed Zener voltage range of 5.90 V to 6.50 V when tested at 5 mA DC with a 40 ms pulse. This ±4.8% tolerance ensures reliable clamping for 5 V logic systems while accommodating process variation across production lots. The specification applies per individual diode within the quad array, and all four devices are matched within this band.
Does HZM6.2Z4MFATL-E support bidirectional ESD protection?
Yes, HZM6.2Z4MFATL-E provides bidirectional ESD protection: each Zener diode conducts in reverse breakdown above 6.2 V and in forward conduction below −0.7 V, meeting IEC 61000-4-2 requirements for both contact and air discharge in forward and reverse polarity. The 8 kV rating is verified under both polarities using the 150 pF/330 Ω network.
Can HZM6.2Z4MFATL-E replace four discrete 1N4735A diodes in a design?
No-HZM6.2Z4MFATL-E is not a drop-in replacement for four discrete 1N4735A diodes. While both have ~6.2 V Zener voltage, the 1N4735A is a 1 W through-hole device with 500 pF capacitance and no ESD rating. HZM6.2Z4MFATL-E is a low-capacitance, quad-monolithic SMT device optimized for signal-line ESD, not power regulation. Its 200 mW total power rating and 4 pF capacitance serve fundamentally different use cases.
What is the thermal derating behavior of HZM6.2Z4MFATL-E above 25°C ambient?
HZM6.2Z4MFATL-E follows linear thermal derating: its 200 mW total power dissipation decreases by 1.6 mW/°C above 25°C ambient, reaching zero at 150°C junction temperature. On a standard 1.6 mm FR-4 PCB with 1.0 mm × 0.6 mm copper pad, maximum allowable ambient temperature is 62°C at full rated power-verified in Fig.2 of the official datasheet.
Is HZM6.2Z4MFATL-E compliant with RoHS and REACH regulations?
Yes, HZM6.2Z4MFATL-E is RoHS-compliant (lead-free termination, homogeneous material restriction) and REACH-conformant, as confirmed by Renesas Electronics' product change notifications and material declarations dated 2010 onward. The MPAK-5 package contains no intentionally added SVHC substances above threshold limits, and full compliance documentation is available upon request from Aetrix Electronics.
