Product details
Overview
SMCJ36AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with a 10/1000 μs waveform, 36 V standoff voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), and 58.1 V maximum clamping voltage (VC) at rated surge current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMCJ36AHM3_A/I datasheet, SMCJ36AHM3_A/I pinout, SMCJ36AHM3_A/I application, or SMCJ36AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown behavior, low incremental surge resistance enables effective energy absorption, and MSL Level 1 rating supports lead-free reflow up to 260 °C peak.
The SMCJ36AHM3_A/I is specified for single-pulse transient suppression per IEC 61000-4-5 and ANSI/IEEE C62.35 standards. Its thermal resistance (RθJA = 75 °C/W) and junction-to-lead resistance (RθJL = 15 °C/W) define derating above 25 °C ambient, and its 200 A IFSM rating supports robust handling of 8.3 ms half-sine surges.

|---|---|
Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp overvoltage before it reaches LDOs or microcontrollers. Use Value: Withstands 1500 W pulses and maintains clamping at ≤58.1 V, preventing damage to 3.3 V/5 V logic interfaces downstream of the SMCJ36AHM3_A/I. | Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) from ESD and inductive switching noise in factory automation sensors. IC Role / Device Role / Timing Role: Parallel-connected TVS referenced to local ground, absorbing sub-100 ns ESD events per IEC 61000-4-2 Level 4. Use Value: 1.0 μA leakage at 36 V ensures minimal impact on loop accuracy; 58.1 V VC limits voltage excursion during 8 kV contact discharge. |
| DC-DC Converter Input Stage | Telecom Power Interface |
Use Scenario: Safeguarding buck converter inputs against ISO 7637-2 Pulse 1 (inductive kickback) and Pulse 3a/b (switching noise) in vehicle infotainment systems. IC Role / Device Role / Timing Role: Primary transient suppressor upstream of input filter capacitors and controller ICs. Use Value: 25.8 A IPPM rating handles worst-case Pulse 1 energy; 40.0–44.2 V VBR aligns with 36 V nominal input while allowing margin for ripple and tolerance. | Use Scenario: Guarding PoE-powered equipment front-ends against lightning-induced surges on 48 V DC distribution lines. IC Role / Device Role / Timing Role: First-line clamping device on power feed, coordinated with upstream gas discharge tubes or MOVs. Use Value: 1500 W PPPM and 58.1 V VC enable coordination with secondary protection stages; SMC package allows high-density layout near connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHM3_A/I | Lower PPPM (600 W), same VWM/VBR/VC, SMB (DO-214AA) package (smaller footprint) | Reduced surge handling; suitable for lower-energy transients or space-constrained layouts | Select when board area is critical and peak surge energy is ≤600 W |
| SMCJ36AHE3_A/I | Same electrical specs, but commercial-grade (non-AEC-Q101), RoHS-compliant with brominated flame retardant | Lacks automotive qualification; intended for industrial/commercial use only | Select for cost-sensitive non-automotive designs where AEC-Q101 is not required |
Compared with SMBJ36AHM3_A/I and SMCJ36AHE3_A/I, the SMCJ36AHM3_A/I uniquely combines 1500 W surge capability, AEC-Q101 qualification, and halogen-free construction-making it the preferred choice for automotive power rail protection where reliability, regulatory compliance, and high-energy transient immunity are jointly required.

FAQ
What is the maximum clamping voltage of the SMCJ36AHM3_A/I under full-rated surge conditions?
The SMCJ36AHM3_A/I has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current (IPPM) of 25.8 A using a 10/1000 μs waveform. This value is measured at the device terminals and defines the highest voltage imposed on the protected circuit during a full 1500 W transient event. The SMCJ36AHM3_A/I maintains this clamping performance across its qualified operating temperature range.
Is the SMCJ36AHM3_A/I suitable for automotive applications?
Yes, the SMCJ36AHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" suffix and documented in Vishay's official datasheet revision 09-Jan-2024. It meets automotive reliability requirements including temperature cycling, highly accelerated life testing (HALT), and ESD immunity. The SMCJ36AHM3_A/I is explicitly recommended for under-hood ECUs, body control modules, and infotainment systems exposed to load dump and ISO 7637-2 transients.
How does the SMCJ36AHM3_A/I differ from the SMCJ36AHE3_A/I variant?
The SMCJ36AHM3_A/I and SMCJ36AHE3_A/I share identical electrical specifications (VWM = 36 V, VBR = 40.0–44.2 V, VC = 58.1 V, PPPM = 1500 W) and SMC package, but differ in qualification and material content: HM3 denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified; HE3 denotes RoHS-compliant and AEC-Q101-qualified but contains brominated flame retardants. The SMCJ36AHM3_A/I is required where halogen-free compliance is mandated.
What is the thermal resistance of the SMCJ36AHM3_A/I, and how does it affect layout design?
The SMCJ36AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, and junction-to-lead resistance (RθJL) of 15 °C/W. To maintain TJ ≤ 150 °C under sustained power dissipation, PCB layout must provide adequate copper area and minimize trace length to ground planes. Derating curves in Figure 2 of the datasheet guide thermal design above 25 °C ambient.
Can the SMCJ36AHM3_A/I be used in bidirectional configurations?
No, the SMCJ36AHM3_A/I is a unidirectional TVS diode, as confirmed by its "A" suffix (vs. "CA" for bidirectional variants like SMCJ36CA). Its cathode band marking and forward voltage drop (VF = 3.5 V at 100 A) confirm asymmetrical conduction. For bidirectional protection, use SMCJ36CA or equivalent; substituting SMCJ36AHM3_A/I in such circuits would result in unintended forward conduction and failure.
