It features a 16 V standoff voltage (VWM), 26.0 V clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMCJ16AHM3/H datasheet, SMCJ16AHM3/H pinout, SMCJ16AHM3/H application, or SMCJ16AHM3/H equivalent, this page delivers verified electrical specs, thermal behavior, AEC-Q101 qualification status, SMC package mechanical data, and real-world protection use cases - all aligned to Vishay Document #88394 (Rev. 09-Jan-2024).
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown above its reverse standoff voltage (VWM = 16 V), limiting transient voltages to ≤26.0 V while conducting up to 57.7 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for repeatable surge immunity in harsh environments.
Rated for -55 °C to +150 °C operating junction temperature, it meets JESD201 Class 2 whisker resistance and MSL Level 1 (260 °C reflow peak), with halogen-free, RoHS-compliant construction per suffix HM3. The cathode band denotes polarity; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin for protected circuitry. |
| VBR min/max | 17.8 V / 19.7 V at IT = 1.0 mA - precise breakdown threshold range ensuring consistent turn-on across production lots. |
| VC @ IPPM | 26.0 V at 57.7 A (10/1000 µs) - clamped voltage seen by downstream components during worst-case surge events. |
| PPPM | 1500 W - peak transient energy absorption capability under standardized surge waveform; enables robust ESD/Lightning-level protection. |
| ID @ VWM | 1.0 µA - ultra-low leakage current at rated standoff voltage, minimizing standby power loss in battery-powered systems. |
| TJ max | +150 °C - maximum junction temperature rating supporting operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 75 °C/W - thermal resistance from junction to ambient (on recommended 8 mm × 8 mm copper pads); informs heatsinking requirements. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode indicated by molded band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential rail in unidirectional TVS configuration. | Provides low-impedance path to reference during surge; must be routed with minimal inductance to preserve clamping speed. |
| Cathode | Current exit terminal in forward bias; marked by band; connected to protected line (e.g., power rail or signal trace). | Defines polarity-sensitive placement; reversal causes catastrophic failure under normal bias - mandatory orientation verification during layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias HAST, and mechanical shock - supports under-hood and ADAS module deployment. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without degradation when properly mounted on 8 mm × 8 mm copper pads. |
| Glass-passivated junction | Ensures stable VBR over lifetime and temperature; eliminates parameter drift due to moisture ingress or surface contamination. |
| MSL Level 1, 260 °C peak | Compatible with standard lead-free reflow profiles without pre-baking; reduces manufacturing complexity and cost. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V or 5 V logic interfaces where margin below absolute maximum ratings is tight. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-M3/86A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W), same VWM/VC specs. | Suitable only for lower-energy transients (IEC 61000-4-5 Level 2); not recommended for automotive load-dump or industrial 4 kV EFT. | Select when board space is constrained and surge threat level is moderate; verify thermal margin with derated IPPM. |
| SMCJ16AHE3_A/H | Identical electrical specs and SMC package, but RoHS-compliant commercial grade (not AEC-Q101 qualified); E3 suffix instead of HM3. | Lacks automotive qualification evidence; acceptable for industrial/commercial designs where AEC-Q101 is not mandated. | Choose for cost-sensitive non-automotive applications requiring same clamping performance without automotive validation overhead. |
Compared with SMCJ16AHM3/H, SMAJ16A-M3/86A trades surge capacity and thermal robustness for compact size, while SMCJ16AHE3_A/H matches performance but omits AEC-Q101 validation - making SMCJ16AHM3/H the sole choice when automotive qualification and full 1500 W surge handling are both required.

FAQ
What is the clamping voltage of SMCJ16AHM3/H and how is it measured?
The SMCJ16AHM3/H has a maximum clamping voltage (VC) of 26.0 V, measured at 57.7 A peak pulse current using the standardized 10/1000 µs double-exponential waveform per ANSI/IEEE C62.35. This value represents the upper limit voltage imposed on the protected circuit during surge events and is guaranteed across the full operating temperature range of -55 °C to +150 °C. The SMCJ16AHM3/H achieves this with low incremental surge resistance, ensuring predictable, repeatable protection behavior.
Is SMCJ16AHM3/H qualified for automotive applications?
Yes, the SMCJ16AHM3/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified version). It undergoes rigorous stress testing including temperature cycling, unbiased HAST, and mechanical shock per AEC-Q101 Rev D, making it suitable for under-hood engine control units, body electronics, and ADAS modules where reliability under thermal and vibration stress is mandatory. The SMCJ16AHM3/H datasheet explicitly references AEC-Q101 compliance in its mechanical data section.
What is the standoff voltage (VWM) and why does it matter for SMCJ16AHM3/H?
The SMCJ16AHM3/H has a reverse standoff voltage (VWM) of 16 V - the maximum continuous DC or RMS voltage the device can block without entering conduction. This parameter defines the operating margin between normal system voltage and clamping onset; for example, it safely protects a nominal 12 V automotive rail where transients may exceed 16 V. Exceeding VWM risks premature conduction and accelerated wear. The SMCJ16AHM3/H's 1.0 µA leakage at VWM ensures minimal impact on system power budget while maintaining tight voltage margin control.
How does the SMCJ16AHM3/H package affect thermal performance?
The SMCJ16AHM3/H uses the SMC (DO-214AB) package, which provides a thermal resistance of 75 °C/W (junction-to-ambient) when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This low RθJA enables reliable operation at full 1500 W surge rating without external heatsinking - critical for space-constrained automotive and industrial PCBs. The package also meets MSL Level 1 and supports lead-free reflow up to 260 °C, aligning with modern manufacturing requirements.
Can SMCJ16AHM3/H replace SMCJ16AHE3_A/H in an existing design?
Yes, the SMCJ16AHM3/H is a direct form-fit-function replacement for SMCJ16AHE3_A/H, sharing identical electrical specifications (VWM = 16 V, VC = 26.0 V, PPPM = 1500 W), SMC package dimensions, and pinout. The only differences are qualification status (HM3 adds AEC-Q101) and material composition (HM3 is halogen-free; HE3 is RoHS-compliant but not halogen-free). No PCB or layout changes are needed - the SMCJ16AHM3/H enhances reliability for automotive use while maintaining full compatibility with commercial-grade SMCJ16AHE3_A/H designs.
