Product details
Overview
HZM16NB1TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 16.94 V to 17.70 V at 5 mA test current, with dynamic resistance of 40 Ω max, power dissipation of 200 mW, and operates within –55°C to +150°C storage range.
For engineers reviewing the HZM16NB1TL-E datasheet, HZM16NB1TL-E pinout, HZM16NB1TL-E application, or HZM16NB1TL-E equivalent, key selection criteria include its B1-grade voltage tolerance (±2.2% typical), MPAK surface-mount package compatibility with high-density PCB layouts, thermal stability up to 150°C junction temperature, and suitability for voltage reference, overvoltage protection, and biasing in industrial sensor interfaces and power supply feedback loops.
Technical Context
The HZM16NB1TL-E employs a silicon epitaxial planar structure optimized for stable reverse-breakdown behavior under DC and pulsed conditions (Pw = 40 ms). Its zener voltage exhibits a positive temperature coefficient of approximately +0.06 mV/°C near 16 V, enabling predictable drift compensation in reference designs.
It functions exclusively in reverse-bias mode with defined anode–cathode polarity, requires no external biasing circuitry, and achieves regulation with minimal quiescent current-reverse leakage remains ≤2 μA at VR = 12.0 V, supporting ultra-low-power standby operation.
Key Specifications

IC Role / Device Role / Timing Role: Reverse-connected clamp between rail and ground, conducting only above 16.94 V threshold. Use Value: Fast turn-on (ns-scale response) and 200 mW power rating absorb repetitive 100 ns–1 μs transients without degradation. |
Use Scenario: Supervisory reset generation for 3.3 V microcontrollers powered from a 15 V intermediate rail via LDO. IC Role / Device Role / Timing Role: Forms precision undervoltage detection threshold by feeding divided rail voltage into comparator input. Use Value: Tight B1-grade VZ tolerance ensures repeatable reset assertion at 14.2–14.9 V, preventing spurious resets during brownout. |
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 (onsemi) | Zener voltage 16.7 V (±5%), 500 mW rating, SOD-123 package, 30 Ω rd | Higher power handling but larger footprint; less tight voltage tolerance | Preferred when higher surge energy absorption is required and board area permits SOD-123 |
| BZX84-C16LT1G (onsemi) | Zener voltage 16 V (±5%), 350 mW rating, SOT-23 package, 40 Ω rd, 3-pin with NC unused | Same pinout (NC-Anode-Cathode), identical MPAK-equivalent footprint, wider VZ tolerance | Suitable for cost-sensitive designs where ±5% regulation is acceptable and legacy SOT-23 tooling exists |
Compared with HZM16NB1TL-E, MMSZ4687T1G offers greater power margin but looser voltage accuracy and larger size, while BZX84-C16LT1G matches the 3-pin MPAK-compatible layout and dynamic resistance but trades B1-grade precision for broader tolerance and higher unit cost in volume.

FAQ
What is the exact zener voltage range specified for HZM16NB1TL-E?
The HZM16NB1TL-E has a guaranteed zener voltage range of 16.94 V to 17.70 V when tested at IZ = 5 mA and Ta = 25°C. This B1-grade specification reflects ±2.2% tolerance around the nominal 17.3 V center point, confirmed in Renesas' R07DS0358EJ0600 datasheet, page 3. The HZM16NB1TL-E is not rated for operation outside this validated range under standard test conditions.
Does HZM16NB1TL-E support bidirectional voltage clamping?
No, the HZM16NB1TL-E is a unidirectional Zener diode intended solely for reverse-bias voltage regulation. Its pinout (Pin 1 = NC, Pin 2 = Anode, Pin 3 = Cathode) and electrical characteristics-including reverse current limits and zener voltage definition-are specified only for cathode-positive biasing. Forward conduction is not characterized or guaranteed, and using HZM16NB1TL-E in forward mode may result in unpredictable performance or reliability risk.
What is the thermal resistance (RθJA) of HZM16NB1TL-E?
The datasheet does not specify junction-to-ambient thermal resistance (RθJA) for HZM16NB1TL-E. Instead, it provides a derating curve in Figure 3 showing power dissipation vs. ambient temperature, with full 200 mW allowed only at Ta ≤ 25°C and linear reduction to zero at ~150°C. For thermal design, engineers should apply the curve directly rather than assume a fixed RθJA value. This applies specifically to the HZM16NB1TL-E in its native MPAK package on standard FR-4 PCB.
Can HZM16NB1TL-E replace HZM16NB2TL-E in the same PCB layout?
Yes, HZM16NB1TL-E and HZM16NB2TL-E share identical MPAK package (PLSP0003ZC-A), pinout, and mechanical dimensions, allowing direct physical substitution. However, their zener voltage ranges differ: HZM16NB1TL-E is 16.94–17.70 V, while HZM16NB2TL-E is 17.56–18.35 V. Substitution affects regulation accuracy and must be verified against system-level voltage tolerance requirements before deployment. The HZM16NB1TL-E is not a drop-in functional replacement unless the higher-voltage band is acceptable.
Is HZM16NB1TL-E compliant with AEC-Q200 or automotive qualification standards?
No, the HZM16NB1TL-E is classified as a "Standard" quality grade device per Renesas' documentation (R07DS0358EJ0600, page 6), intended for computers, office equipment, industrial robots, and consumer electronics-not automotive or safety-critical applications. It is not qualified to AEC-Q200, and Renesas explicitly excludes transportation equipment (including automobiles) from its recommended use cases for this part. For automotive designs, engineers must select a designated "High Quality" or "Specific" grade alternative.
