Product details
Overview
HZM4.7NB2JTL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and power-supply reference circuits, with a nominal zener voltage of 4.7 V (B2 grade: 4.98–5.20 V), 10 µA maximum reverse current at 1.0 V, 130 Ω typical dynamic resistance at 5 mA, and 200 mW power dissipation in MPAK package - used in voltage regulation for sensor biasing, ADC references, and overvoltage protection.
For engineers reviewing the HZM4.7NB2JTL-E datasheet, HZM4.7NB2JTL-E pinout, HZM4.7NB2JTL-E application, or HZM4.7NB2JTL-E equivalent, key selection criteria include zener voltage tolerance (±4.3% for B2 grade), thermal coefficient (≈+0.02 mV/°C near 4.7 V), surface-mount compatibility, and pulse-tested reliability per R07DS0358EJ0600 Rev.6.00.
Technical Context
The HZM4.7NB2JTL-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting excess current to ground when input exceeds its zener threshold. Its epitaxial planar construction ensures tight voltage distribution and low noise performance.
It is characterized under pulsed test conditions (Pw = 40 ms) to minimize self-heating effects, with absolute maximum junction temperature rated at 150°C and storage range from –55°C to +150°C - enabling use in industrial ambient environments without derating below 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.98–5.20 V (B2 grade); defines stable regulation point for reference circuits requiring ±4.3% tolerance. |
| Test Current (IZ) | 5 mA; standard bias condition for measuring VZ and dynamic resistance - matches typical low-current reference design points. |
| Dynamic Resistance (rd) | 130 Ω max at 5 mA; determines output impedance and load regulation sensitivity in feedback paths. |
| Reverse Current (IR) | 10 µA max at VR = 1.0 V; indicates leakage level critical for battery-powered or high-impedance bias networks. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C; sets maximum continuous power handling before thermal derating begins. |
| Junction Temperature (Tj) | 150°C max; defines upper thermal limit for reliable long-term operation in enclosed or high-ambient designs. |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A, Renesas code MPAK(D)V) - ultra-small surface-mount outline measuring 2.7 × 1.35 × 0.95 mm (L × W × H), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or mechanical stress on die. |
| 2 | Anode | Input terminal for reverse-bias configuration; connects to lower-potential node in shunt regulation topology. |
| 3 | Cathode | Output/reference terminal; held at stabilized VZ above anode potential when conducting. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±4.3% (4.98–5.20 V), tighter than standard B-grade parts - improves accuracy in precision reference designs. |
| Pulsed characterization (40 ms) | Ensures stable VZ measurement without thermal drift - critical for production test repeatability and spec compliance. |
| MPAK surface-mount package | 0.95 mm height and 2.7 mm length enable placement in space-constrained modules like IoT sensor nodes and portable instrumentation. |
| Low dynamic resistance | 130 Ω max supports stable regulation under varying load currents up to ~10 mA - suitable for driving op-amp inputs or ADC references. |
Applications
| Industrial Sensor Biasing | ADC Reference Voltage Source |
|---|---|
|
Use Scenario: Providing stable excitation voltage to resistive bridge sensors (e.g., strain gauges, RTDs) in PLC analog input modules. IC Role / Device Role / Timing Role: Shunt voltage reference establishing fixed bias point independent of supply ripple or load variation. Use Value: Enables <1 LSB error in 12-bit ADC conversions by holding reference within ±0.5 mV over –40°C to +85°C ambient. |
Use Scenario: Generating precise 4.7 V reference for SAR ADCs in data acquisition systems with single-supply rails. IC Role / Device Role / Timing Role: Low-noise, low-drift voltage source replacing larger IC references where board space is constrained. Use Value: Delivers <0.02%/°C TC and <10 µA leakage - sufficient for 10-bit accuracy without trimming or calibration. |
| Overvoltage Clamp Protection | Microcontroller Reset Circuit |
|
Use Scenario: Clamping I/O line voltage during ESD transients or supply surges in automotive body control modules. IC Role / Device Role / Timing Role: Fast-acting shunt limiter diverting surge current away from sensitive CMOS inputs. Use Value: Responds within nanoseconds to 1 kV HBM events while limiting clamped voltage to ≤5.2 V - protecting 5 V tolerant GPIOs. |
Use Scenario: Generating clean, monotonic reset signal for Cortex-M0 microcontrollers during brown-out conditions. IC Role / Device Role / Timing Role: Threshold detector combined with RC delay network to hold reset until VCC stabilizes above 4.7 V. Use Value: Guarantees deterministic release at 4.98 V minimum - eliminating false resets caused by supply ripple near 5 V rail. |
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 |
|---|---|---|---|
| BZX84-C4V7LT1G | 4.7 V ±5% (±0.235 V), SOT-23 package, 350 mW Pd, 90 Ω rd | Higher power rating but larger footprint; better for higher-current clamping, less suited for ultra-dense layouts. | Select when >200 mW dissipation or lower dynamic resistance is required; verify PCB pad compatibility with SOT-23 vs. MPAK. |
| MMSZ4704T1G | 4.7 V ±5%, SOD-123 package, 500 mW Pd, 100 Ω rd, –55°C to +150°C rating | Larger thermal mass and higher power capability; less sensitive to trace heating in high-reliability industrial designs. | Prefer for extended temperature operation with margin or where JEDEC-standard SOD-123 footprint is already standardized in BOM. |
Compared with BZX84-C4V7LT1G and MMSZ4704T1G, the HZM4.7NB2JTL-E offers tighter voltage tolerance (±4.3% vs. ±5%), smaller MPAK footprint (2.7 × 1.35 mm vs. 2.9 × 1.3 mm SOT-23), and grade-specific binning - making it optimal for space-limited, high-accuracy analog reference roles where 200 mW suffices.

FAQ
What is the exact zener voltage range for HZM4.7NB2JTL-E?
The HZM4.7NB2JTL-E has a guaranteed zener voltage range of 4.98 V to 5.20 V at 5 mA test current, corresponding to its B2 grade designation per R07DS0358EJ0600 Rev.6.00. This ±4.3% tolerance is tighter than the standard B-grade (±5.3%) and enables improved accuracy in reference and regulation circuits where HZM4.7NB2JTL-E is deployed.
Is HZM4.7NB2JTL-E suitable for use in automotive applications?
HZM4.7NB2JTL-E is classified as a Standard-grade Renesas product, qualified for industrial and commercial applications including computers, office equipment, and test instrumentation - but not certified for automotive AEC-Q101 or "High Quality" transportation use. For automotive designs, HZM4.7NB2JTL-E requires additional system-level qualification; consult Renesas' official automotive product portfolio for AEC-compliant alternatives.
Does HZM4.7NB2JTL-E have a built-in temperature compensation circuit?
No, HZM4.7NB2JTL-E is a passive silicon Zener diode without active temperature compensation. Its zener voltage exhibits a positive temperature coefficient of approximately +0.02 mV/°C near 4.7 V, as shown in Figure 2 of the datasheet. System-level compensation (e.g., using complementary diodes or op-amp circuits) is required if <100 ppm/°C stability is needed - HZM4.7NB2JTL-E itself provides no internal compensation.
What does the 'B2' suffix mean in HZM4.7NB2JTL-E?
The 'B2' in HZM4.7NB2JTL-E denotes the zener voltage grade bin: B2 specifies a tighter 4.98–5.20 V range at 5 mA, distinct from B1 (4.84–5.04 V) and B3 (4.69–4.90 V). This binning allows designers to select HZM4.7NB2JTL-E when a specific mid-range 4.7 V stabilization point with ±4.3% tolerance is required - improving yield and reducing post-manufacturing calibration effort.
Can HZM4.7NB2JTL-E replace a 5.1 V Zener diode in an existing design?
No - HZM4.7NB2JTL-E is specified for 4.7 V nominal regulation (4.98–5.20 V), not 5.1 V. Substituting it for a 5.1 V part (e.g., HZM5.1NB3JTL-E) would shift the regulated voltage downward by ~300 mV, potentially causing undervoltage faults in reset circuits or inaccurate scaling in reference paths. Always match the target zener voltage grade and tolerance; HZM4.7NB2JTL-E must be used only where 4.7 V stabilization is explicitly required.
