Product details
Overview
P6SMB16AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 16 V standoff voltage (VWM = 13.6 V), 22.5 V clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform - deployed for overvoltage protection of MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB16AHM3_A/I datasheet, P6SMB16AHM3_A/I pinout, P6SMB16AHM3_A/I application, or P6SMB16AHM3_A/I equivalent, this part delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified clamping performance under repetitive surge conditions - critical for robust ESD and load-switch transient suppression in production-grade designs.
Technical Context
The P6SMB16AHM3_A/I operates as a unidirectional avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients and low incremental surge resistance. Its breakdown voltage is specified at 15.2–16.8 V (IT = 1.0 mA), with maximum reverse leakage of 1.0 μA at VWM = 13.6 V.
Thermally, it features RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C junction temperature. It is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and meets J-STD-020 MSL Level 1 with 260 °C reflow peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/52 | Same VWM (13.6 V), identical SMB package, but lower PPPM = 400 W and no AEC-Q101 qualification | Not suitable for automotive or high-reliability industrial use; limited to commercial-grade consumer products | Select only if cost sensitivity outweighs surge margin and qualification requirements |
| 1.5SMC16A | Higher package thermal resistance (RθJA ≈ 125 °C/W), same VBR range, but SMC (DO-214AB) footprint requires PCB redesign | Requires layout change; less suitable for space-constrained SMB layouts | Choose only when existing SMC footprint exists and thermal derating is acceptable |
Compared with SMAJ16A-E3/52 and 1.5SMC16A, the P6SMB16AHM3_A/I provides higher surge robustness (600 W vs. 400 W), automotive qualification, and drop-in compatibility with standard SMB land patterns - making it the preferred choice for mission-critical protection where reliability and layout continuity are mandatory.

FAQ
What is the clamping voltage of the P6SMB16AHM3_A/I at its rated peak pulse current?
The P6SMB16AHM3_A/I has a maximum clamping voltage (VC) of 22.5 V at IPPM = 26.7 A using the 10/1000 μs waveform. This value is measured under standardized test conditions with 0.2" × 0.2" copper pads and represents the upper limit of voltage imposed on the protected circuit during worst-case surge events. The P6SMB16AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the P6SMB16AHM3_A/I suitable for automotive applications?
Yes, the P6SMB16AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and "_B" revision code in its ordering designation. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and surge endurance validation per automotive standards. The P6SMB16AHM3_A/I is explicitly rated for under-hood and chassis-mounted use with TJ max = +150 °C and MSL Level 1 reflow compatibility.
What does the "HM3_A/I" suffix mean in P6SMB16AHM3_A/I?
The "HM3" denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification; "A" specifies the revision level per Vishay's internal documentation; "I" indicates packaging in 13-inch tape-and-reel format (3200 units per reel). This full suffix confirms the P6SMB16AHM3_A/I meets automotive-grade material, reliability, and logistics requirements - distinct from commercial-grade "E3" or "M3" variants.
How does the P6SMB16AHM3_A/I compare to bidirectional TVS diodes like P6SMB16CA?
The P6SMB16AHM3_A/I is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., power rails or single-ended signals), offering lower leakage (<1.0 μA at 13.6 V) and tighter VBR tolerance. In contrast, P6SMB16CA is bidirectional and suited for AC or floating lines (e.g., RS-485), but exhibits higher leakage and asymmetric clamping behavior. The P6SMB16AHM3_A/I cannot substitute for P6SMB16CA in AC-coupled applications without circuit redesign.
What thermal design guidance applies to the P6SMB16AHM3_A/I in high-power surge scenarios?
For reliable operation under repetitive 600 W surges, the P6SMB16AHM3_A/I must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the datasheet. Its RθJA = 100 °C/W assumes this layout; reducing pad area increases junction temperature rise and risks thermal runaway. Derating curves (Fig. 2) show >50% power reduction above 75 °C ambient - the P6SMB16AHM3_A/I requires careful thermal modeling in enclosed or high-ambient environments.
