Product details
Overview
HZD6.2Z4KRF-P-E from Renesas Electronics is a silicon planar Zener diode engineered for ESD and surge protection on low-capacitance signal lines, with a nominal Zener voltage of 6.2 V (5.9–6.5 V at 5 mA), maximum capacitance of 4.0 pF, dynamic resistance ≤60 Ω, and ESD capability of 8 kV (IEC 61000-4-2, 150 pF/330 Ω). It is used in high-speed interface protection such as USB 2.0, HDMI, and LVDS data lines.
For engineers reviewing the HZD6.2Z4KRF-P-E datasheet, HZD6.2Z4KRF-P-E pinout, HZD6.2Z4KRF-P-E application, or HZD6.2Z4KRF-P-E equivalent, key selection criteria include low clamping voltage under transient stress, sub-4-pF junction capacitance for minimal signal distortion, 150 mW power dissipation limit, SFP package compatibility with fine-pitch PCB layouts, and verified 8 kV contact ESD robustness in both forward and reverse bias.
Technical Context
This device operates as a bidirectional transient voltage suppressor leveraging Zener breakdown in reverse bias and forward conduction during positive transients. Its 6.2 V nominal regulation voltage targets logic-level signal line protection where clamping must occur below IC absolute maximum ratings.
The SFP (Super small Flat Package) construction enables surface-mount integration into space-constrained interfaces, while its 4.0 pF capacitance ensures <0.1 dB insertion loss up to 500 MHz - critical for maintaining signal integrity in high-speed digital links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 5.9–6.5 V at IZ = 5 mA; clamps transients before downstream logic damage |
| Capacitance (C) | ≤4.0 pF at VR = 0 V, f = 1 MHz; preserves signal rise/fall times in >100 Mbps links |
| Dynamic resistance (rd) | ≤60 Ω at IZ = 5 mA; ensures stable clamping voltage under fast-rising surges |
| ESD capability | 8 kV per IEC 61000-4-2 (150 pF/330 Ω); withstands 10 pulses in both directions without IR degradation |
| Power dissipation (Pd) | 150 mW at Ta = 25°C; limits thermal stress during repetitive low-energy transients |
| Reverse current (IR) | ≤3 µA at VR = 5.5 V; avoids leakage-induced offset in precision analog inputs |

Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs against ESD events during hot-plug insertion. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 4.0 pF capacitance prevents eye diagram degradation; 6.2 V clamping avoids exceeding USB PHY's 6.5 V abs max rating. | Use Scenario: Shielding TMDS clock and data channels from electrostatic discharge in display interface cables. IC Role / Device Role: Low-capacitance Zener clamp on each TMDS pair, grounded via shortest possible trace. Use Value: Sub-4 pF loading maintains 165 MHz pixel clock integrity; 8 kV ESD rating exceeds HDMI compliance requirement. |
| LVDS Interface Receivers | Industrial Sensor Signal Conditioning |
Use Scenario: Guarding LVDS receiver inputs against field-induced transients in factory automation systems. IC Role / Device Role: Point-of-entry Zener clamp on differential input pins, referenced to common-mode voltage. Use Value: ≤60 Ω dynamic resistance ensures fast response to 1 ns rise-time transients; low leakage avoids DC offset errors. | Use Scenario: Protecting analog sensor outputs (e.g., 4–20 mA loop transmitters) from induced surges in harsh industrial environments. IC Role / Device Role: Reverse-biased Zener shunt across output-to-ground, sized for 150 mW non-repetitive surge handling. Use Value: 150 mW Pd supports short-duration transients per Fig.3; 150°C junction rating allows operation near heat-generating PLC modules. |
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 |
|---|---|---|---|
| NSZ6.2A2T5G | Same 6.2 V nominal Zener voltage, but higher capacitance (12 pF) and lower ESD rating (4 kV) | Less suitable for >100 Mbps interfaces due to higher C; acceptable for slower RS-485 or GPIO protection | Select only when board layout constraints allow larger capacitance or ESD threat level is lower |
| CM1213-04SO | Quad-channel TVS array with 6.8 V breakdown, 0.5 pF per channel, but requires 4-pin SOIC footprint | Offers multi-line protection in single package; incompatible with SFP space constraints | Choose when protecting ≥2 signal lines simultaneously and PCB area permits SOIC-8 |
Compared with NSZ6.2A2T5G and CM1213-04SO, HZD6.2Z4KRF-P-E uniquely balances ultra-low capacitance (4 pF), compact SFP size, and 8 kV ESD robustness - making it optimal for single-line, space-limited, high-speed interface protection where discrete placement and minimal parasitics are mandatory.

FAQ
What is the Zener voltage tolerance of HZD6.2Z4KRF-P-E?
The HZD6.2Z4KRF-P-E has a specified Zener voltage range of 5.9 V to 6.5 V at 5 mA test current, measured under 40 ms pulse conditions. This ±0.3 V tolerance ensures predictable clamping behavior across process variation and temperature, making HZD6.2Z4KRF-P-E suitable for protecting 3.3 V and 5 V logic interfaces without risking over-clamp or under-clamp failure modes.
Does HZD6.2Z4KRF-P-E meet IEC 61000-4-2 ESD standards?
Yes, HZD6.2Z4KRF-P-E is rated for 8 kV contact discharge per IEC 61000-4-2, tested with 150 pF capacitance and 330 Ω series resistance in both forward and reverse directions. The failure criterion - reverse current remaining ≤3 µA after 10 pulses at VR = 5.5 V - confirms robust post-ESD functionality, a key verification included in the official Renesas datasheet for HZD6.2Z4KRF-P-E.
What is the maximum operating temperature for HZD6.2Z4KRF-P-E?
HZD6.2Z4KRF-P-E supports a junction temperature range up to +150°C and storage temperatures from −55°C to +150°C. Its thermal design accommodates ambient operation near heat-generating components in industrial control panels, provided PCB copper area and airflow comply with the derating curve in Figure 2 of the HZD6.2Z4KRF-P-E datasheet.
Can HZD6.2Z4KRF-P-E be used in bidirectional signal paths?
Yes, HZD6.2Z4KRF-P-E functions bidirectionally: it clamps positive transients via forward conduction (anode-to-cathode) and negative transients via Zener breakdown (cathode-to-anode). Its symmetric 8 kV ESD rating in both polarities and low dynamic resistance make HZD6.2Z4KRF-P-E appropriate for AC-coupled or differential signal lines like USB D+/D− or LVDS pairs.
Is the SFP package of HZD6.2Z4KRF-P-E compatible with standard reflow profiles?
Yes, the SFP package of HZD6.2Z4KRF-P-E is qualified for standard lead-free reflow soldering per J-STD-020, with peak temperature up to 260°C. However, Renesas explicitly advises against hand-soldering with soldering irons due to mechanical stress risks - automated reflow is required to maintain long-term reliability of HZD6.2Z4KRF-P-E.
