Product details
Overview
SMCJ13AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed on DC power rails and I/O lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCJ13AHM3_A/I datasheet, SMCJ13AHM3_A/I pinout, SMCJ13AHM3_A/I application, or SMCJ13AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant construction (HM3 suffix), low incremental surge resistance, and verified clamping performance under repetitive transients per ISO 7637-2 and IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds the breakdown threshold (VBR = 14.4–15.9 V at 1 mA), it avalanches to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response (<1 ns), while the SMC package provides thermal robustness with RθJA = 75 °C/W and RθJL = 15 °C/W.
Rated for -55 °C to +150 °C operation, the SMCJ13AHM3_A/I supports high-reliability applications requiring MSL Level 1 handling (260 °C reflow peak) and JESD201 Class 2 whisker resistance. Its unidirectional polarity-marked by cathode band-enables integration into DC-biased signal or power paths without reverse conduction concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 13 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 21.5 V at 69.8 A (10/1000 µs) - Maximum voltage seen by protected circuit during worst-case surge; determines IC survivability. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 µs transients; validates compliance with IEC 61000-4-5 Level 4. |
| IPPM (Peak Pulse Current) | 69.8 A - Peak surge current the device safely clamps; directly relates to system-level surge generator capability. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with minimal derating. |
| Leakage (ID) | ≤1.0 µA at VWM - Ultra-low reverse leakage preserves battery life and avoids false triggers in low-power sensor nodes. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow). Cathode indicated by molded band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes shunt path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Halogen-free & RoHS-compliant (HM3) | Meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 1 halogen-free requirements. |
| Low clamping ratio (VC/VWM ≈ 1.65) | Minimizes overvoltage stress on downstream ICs compared to higher-ratio TVS devices. |
| Fast response time (<1 ns) | Ensures protection before transient-induced damage occurs in CMOS logic and microcontrollers. |
| MSL Level 1 rating | Enables standard SMT assembly without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Body Control Module (BCM) | Industrial CAN Transceiver Protection |
|---|---|
Use Scenario: Protecting 12 V supply input and LIN bus lines in BCM against load dump and inductive switching transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13AHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VC specs. | Not suitable for IEC 61000-4-5 Level 4; limited to consumer-grade or low-energy industrial transients. | Select when board space is constrained and surge threat level is ≤ 1 kV/0.5 J. |
| SMCJ13AHE3_A/I | Same SMC package and electrical specs, but RoHS-compliant commercial grade (E3), not halogen-free or AEC-Q101 qualified. | Lacks automotive qualification and halogen-free certification; unsuitable for Tier-1 automotive BOMs. | Select for cost-sensitive industrial applications where AEC-Q101 and halogen-free status are not mandated. |
Compared with SMAJ13AHE3_A/I and SMCJ13AHE3_A/I, the SMCJ13AHM3_A/I uniquely delivers full 1500 W surge capability in an AEC-Q101/halogen-free package-making it the only option among the three qualified for under-hood automotive deployment and high-reliability industrial systems requiring traceable green materials.

FAQ
What is the maximum clamping voltage of the SMCJ13AHM3_A/I under a 10/1000 µs surge?
The SMCJ13AHM3_A/I has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 69.8 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024 (Document Number: 88394). The SMCJ13AHM3_A/I maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C) with minimal drift.
Is the SMCJ13AHM3_A/I suitable for automotive applications?
Yes, the SMCJ13AHM3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HM3 suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It meets MSL Level 1 reflow requirements and is validated for temperature cycling, high-temperature reverse bias, and ESD robustness per the AEC-Q101 stress test plan. The SMCJ13AHM3_A/I is routinely deployed in body control modules, lighting drivers, and ADAS sensor interfaces where sustained reliability under thermal and electrical stress is critical.
How does the SMCJ13AHM3_A/I differ from the SMCJ13AHE3_A/I?
The SMCJ13AHM3_A/I and SMCJ13AHE3_A/I share identical electrical specifications (VWM, VBR, VC, PPPM) and SMC package, but differ in material compliance and qualification: the HM3 version is halogen-free and AEC-Q101 qualified, whereas the HE3 version is RoHS-compliant only (not halogen-free) and lacks automotive qualification. The SMCJ13AHM3_A/I is required for Tier-1 automotive designs, while the SMCJ13AHE3_A/I serves general industrial applications where those certifications are unnecessary.
What is the reverse leakage current of the SMCJ13AHM3_A/I at its standoff voltage?
The SMCJ13AHM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 13 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage is maintained across its full operating temperature range and ensures minimal power loss in battery-powered or always-on circuits. The SMCJ13AHM3_A/I achieves this performance through glass-passivated junction technology, which stabilizes leakage behavior over time and thermal cycling.
Can the SMCJ13AHM3_A/I be used in bidirectional configurations?
No-the SMCJ13AHM3_A/I is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SMCJ13CA). Using the SMCJ13AHM3_A/I in reverse-biased configurations risks permanent failure due to forward conduction during negative transients. Always verify polarity alignment during PCB layout; the SMCJ13AHM3_A/I must be oriented with the banded end toward the protected line and the anode to ground or reference potential.
