Product details
Overview
HZM27FATL-E from Renesas Electronics is a silicon epitaxial planar Zener diode array with four integrated surge-absorbing elements in a single MPAK-5 surface-mount package. It delivers 27 V nominal Zener voltage (25.1–28.9 V at 2 mA), 200 mW total power dissipation, and 30 kV ESD capability (per IEC 61000-4-2 equivalent test). It is used for transient voltage suppression in low-power signal lines of consumer electronics interfaces.
For engineers reviewing the HZM27FATL-E datasheet, HZM27FATL-E pinout, HZM27FATL-E application, or HZM27FATL-E equivalent, key selection criteria include its quad-cathode/anode configuration, 27 V clamping threshold, 70 Ω dynamic resistance, 2 µA reverse leakage at 21 V, and suitability for high-density PCB layouts requiring compact TVS protection without discrete arrays.
Technical Context
The HZM27FATL-E integrates four independent Zener diodes sharing a common anode terminal (Pin 4) and separate cathodes (Pins 1, 2, 3, 5), enabling multi-line bidirectional surge clamping in a single footprint. Its 27 V nominal breakdown voltage is specified under 40 ms pulsed conditions at 2 mA, with tight tolerance (±1.9 V) ensuring predictable clamping behavior across temperature.
Designed for surface-mount assembly on FR-4 PCBs with 1.6 mm thickness and copper foil, the device operates up to 150 °C junction temperature and supports storage from −55 °C to +150 °C. Its 27 pF capacitance at 0 V and 1 MHz makes it suitable for low-speed data lines where signal integrity must be preserved during transient events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based surge suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF27A (ON Semiconductor) | Single-channel 27 V TVS diode in SOD-123; no multi-element integration | Requires four discrete placements for same channel count; higher layout area | Select when board space permits discrete routing and lower per-device cost is prioritized |
| P6SMB27A (Littelfuse) | 600 W peak pulse power, DO-214AA package; higher surge capacity but larger footprint | Better suited for AC mains or high-energy transients; not optimized for high-density signal lines | Select when protecting higher-energy lines (e.g., 12 V sensor buses) where clamping speed and capacitance are secondary |
Compared with SMF27A and P6SMB27A, the HZM27FATL-E uniquely combines quad-channel integration, 27 pF low capacitance, and MPAK-5 miniaturization-making it optimal for space-constrained, multi-signal I/O protection where consistent 27 V clamping and ESD robustness are required.

FAQ
What is the Zener voltage tolerance of HZM27FATL-E at 2 mA test current?
The HZM27FATL-E has a Zener voltage range of 25.10 V to 28.90 V when measured at IZ = 2 mA with a 40 ms pulse. This ±1.9 V deviation from the nominal 27 V value ensures predictable clamping performance across production lots and operating temperatures, critical for reliable interface-level surge protection design.
How many independent Zener elements does HZM27FATL-E contain, and how are they configured?
The HZM27FATL-E contains four independent silicon epitaxial planar Zener diodes. Pins 1, 2, 3, and 5 serve as individual cathodes, while Pin 4 is the common anode. This configuration enables simultaneous protection of up to four signal lines referenced to a shared ground or supply rail without inter-channel coupling.
What is the maximum junction temperature rating for HZM27FATL-E, and how does it affect PCB layout?
The HZM27FATL-E supports a maximum junction temperature of 150 °C. To maintain reliability, PCB layout must ensure adequate copper pour and thermal relief around the MPAK-5 pads-especially under continuous 200 mW dissipation-and avoid placing heat-generating components nearby. The device's thermal derating curve (Fig.2) shows linear Pd reduction above 25 °C ambient.
Does HZM27FATL-E meet industry-standard ESD immunity requirements, and what test method applies?
Yes, the HZM27FATL-E achieves 30 kV ESD immunity per the Human Body Model (HBM) using C = 150 pF and R = 330 Ω, tested in both forward and reverse directions for 10 pulses. This exceeds IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) and qualifies the HZM27FATL-E for use in consumer electronics ports exposed to frequent handling.
Can HZM27FATL-E be used in automotive applications, and what quality grade does it carry?
The HZM27FATL-E is classified as a "Standard" quality grade device per Renesas documentation, intended for consumer and industrial applications-not automotive safety-critical systems. It is suitable for non-safety infotainment peripherals (e.g., keypad scan lines), but not for powertrain, ADAS, or chassis control modules requiring "High Quality" or "Specific" grade assurance.
