Product details
Overview
HZM6.8Z4MFATL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 6.86 V (min) to 7.14 V (max) at 5 mA test current, dynamic resistance of 3.5 Ω max, and power dissipation rating of 200 mW in the MPAK surface-mount package.
For engineers reviewing the HZM6.8Z4MFATL-E datasheet, HZM6.8Z4MFATL-E pinout, HZM6.8Z4MFATL-E application, or HZM6.8Z4MFATL-E equivalent, this device serves as a compact, high-stability voltage reference for sensor biasing, power supply feedback loops, and overvoltage protection in space-constrained industrial and consumer electronics designs.
Technical Context
The HZM6.8Z4MFATL-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting reverse-biased zener breakdown. Its epitaxial planar structure ensures tight voltage tolerance and low temperature coefficient (±0.03 mV/°C typical near 6.8 V).
Designed for surface-mount assembly in high-density PCB layouts, it uses pulse-tested electrical characterization (Pw = 40 ms) per JEITA standard, with junction temperature limited to 150°C and storage range spanning –55°C to +150°C - enabling reliable operation in ambient temperatures up to 85°C at full rated power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.86 V min to 7.14 V max at IZ = 5 mA - defines stable regulation window for reference design |
| Dynamic Resistance (rd) | 3.5 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating |
| Reverse Current (IR) | 2 µA max at VR = 5 V - indicates leakage level critical for low-current bias networks |
| Junction Temperature (Tj) | 150°C max - defines upper thermal limit for reliability under sustained conduction |
| Package Type | MPAK (PLSP0003ZC-A) - 3-pin SMT package with NC, anode, cathode layout for automated placement |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A), 3-terminal surface-mount device with 1.0 mm × 1.3 mm footprint, 0.55 mm nominal terminal pitch, and 0.16 mm min lead thickness - optimized for reflow soldering and high-density PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal - must remain unconnected to avoid parasitic coupling or mechanical stress |
| 2 | Anode | Forward-biased terminal during normal operation; tied to lower potential side of regulated node |
| 3 | Cathode | Zener breakdown terminal; connected to higher potential side and output reference point |
Key Features
| Feature | Design Value |
|---|---|
| Grade B3 Zener Voltage Tolerance | ±2.1% (6.86–7.14 V @ 5 mA) - enables tighter reference accuracy than standard-grade Zeners |
| Low Dynamic Resistance | 3.5 Ω max - improves line/load regulation and reduces output ripple in feedback paths |
| MPAK Surface-Mount Package | 0.55 mm pin pitch, 1.0 × 1.3 mm body - supports fine-pitch automated assembly and board area savings |
| Temperature Coefficient | ±0.03 mV/°C near 6.8 V - minimizes drift over industrial temperature range (–40°C to +85°C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687T1G | Zener voltage 6.8 V ±5%, rd = 5 Ω max, SOD-123 package (2.7 × 1.6 mm) | Larger footprint and looser tolerance - suitable where board space and accuracy are less constrained | Select when cost sensitivity outweighs precision and miniaturization requirements |
| BZX84-C6V8 | Zener voltage 6.8 V ±5%, rd = 40 Ω max, SOT-23 package (3.0 × 1.4 mm) | Higher dynamic resistance degrades regulation under variable load - limits use to non-critical biasing | Choose only for legacy designs or non-precision applications with existing SOT-23 footprints |
Compared with MMSZ4687T1G and BZX84-C6V8, the HZM6.8Z4MFATL-E delivers superior voltage stability (±2.1% vs. ±5%), lower impedance (3.5 Ω vs. ≥5 Ω), and smaller MPAK footprint - making it optimal for next-generation compact, high-accuracy reference designs.

FAQ
What is the exact zener voltage range for HZM6.8Z4MFATL-E at 5 mA?
The HZM6.8Z4MFATL-E has a guaranteed zener voltage range of 6.86 V (minimum) to 7.14 V (maximum) when tested at IZ = 5 mA and Ta = 25°C. This corresponds to Grade B3 tolerance per the R07DS0358EJ0600 datasheet, and applies strictly to the HZM6.8Z4MFATL-E variant - not the broader HZM6.8N family.
Is HZM6.8Z4MFATL-E pin-compatible with other devices in the HZM-N series?
Yes - all HZM-N series diodes, including HZM6.8Z4MFATL-E, share identical MPAK (PLSP0003ZC-A) packaging and pinout: Pin 1 = NC, Pin 2 = Anode, Pin 3 = Cathode. This allows direct substitution within the same voltage grade without PCB redesign, provided thermal and electrical constraints are verified.
Does HZM6.8Z4MFATL-E require external heat sinking in standard operation?
No - the HZM6.8Z4MFATL-E is rated for 200 mW power dissipation at Ta = 25°C with no heatsink required. Derating begins above 25°C ambient per Fig.3 in the datasheet; at 85°C ambient, usable power drops to ~120 mW. Standard FR-4 PCB copper area provides sufficient thermal path for typical reference applications.
What does the "Z4M" suffix indicate in HZM6.8Z4MFATL-E?
The "Z4M" segment denotes Renesas' internal marking code for the HZM6.8N B3 grade variant - confirmed by Page 4 of R07DS0358EJ0600, where "HZM6.8N B3" maps to mark code "683". The "FATL-E" suffix specifies tape-and-reel packaging (TL), RoHS-compliant finish, and industrial-grade qualification.
Can HZM6.8Z4MFATL-E be used in automotive applications?
The HZM6.8Z4MFATL-E is classified as a "Standard" quality grade device per Renesas' quality policy (Page 6, Note 7), intended for industrial and consumer equipment - not automotive safety-critical systems. For AEC-Q200 qualified alternatives, consult Renesas' automotive-grade Zener portfolio separately.
