Product details
Overview
SMBJ16C-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMBJ16C-E3/5B datasheet, SMBJ16C-E3/5B pinout, SMBJ16C-E3/5B application, or SMBJ16C-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 100 °C/W), unidirectional polarity marking, and RoHS-compliant matte tin-plated terminals suitable for automated placement on consumer, industrial, and telecom PCBs.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (VBR min = 17.8 V, max = 19.7 V at 1.0 mA), it rapidly transitions from high-impedance to low-impedance state to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surge stress.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and exhibits low incremental surge resistance - critical for minimizing voltage overshoot during fast-rising transients such as ESD or inductive kickback in DC power rails and signal lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12–15 V DC systems. |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - Breakdown voltage range confirming reliable turn-on within specification; ensures consistent protection across production lots. |
| VC @ IPPM | 26.0 V at 23.1 A - Clamping voltage under standardized 10/1000 µs surge; limits voltage seen by protected circuit to ≤26 V during worst-case transient. |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 µs waveform; supports robust protection against IEC 61000-4-5 Level 3/4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating requirements above 25 °C ambient. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); validates survivability during accidental reverse-bias misapplication or fault conditions. |
| Polarity | Unidirectional - Cathode marked by band; blocks forward conduction until breakdown, enabling use in DC supply rail protection without rectification interference. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes clamping loop when transient exceeds VWM. |
| Cathode | High-side connection point | Marked with band; connects to protected line (e.g., 12 V rail or signal input); conducts avalanche current during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 surge immunity requirements for industrial and telecom equipment without external heat sinking. |
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics over temperature and lifetime, reducing parameter drift in harsh environments. |
| MSL Level 1 rating (260 °C peak) | Supports standard lead-free reflow profiles without moisture-induced failure, eliminating pre-bake requirement for SMT assembly. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental regulations; matte tin plating provides reliable solder wetting and intermetallic formation in high-volume manufacturing. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients (<1 ns rise time), improving protection effectiveness for CMOS logic and microcontroller I/O pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/5B | Same VWM (16 V), identical SMB package and pinout; differs only in marking code (no "C" suffix), indicating same unidirectional configuration. | No functional difference; SMBJ16A-E3/5B is the base designation - SMBJ16C-E3/5B reflects Vishay's internal revision or traceability coding. | Select SMBJ16C-E3/5B when traceability to latest revision (Revision: 09-Jan-2024) and documented compliance with J-STD-020 MSL Level 1 is required. |
| 1.5SMC16A | Same VWM (16 V), 600 W PPPM, but in larger SMC (DO-214AB) package; RθJA ≈ 50 °C/W vs. 100 °C/W for SMBJ16C-E3/5B. | Higher thermal mass allows higher sustained surge duty cycles; less suitable for space-constrained layouts where SMB footprint is mandatory. | Choose 1.5SMC16A only if board layout permits larger SMC package and improved thermal performance justifies added area and weight. |
Compared with SMBJ16A-E3/5B, SMBJ16C-E3/5B offers identical electrical and mechanical performance with enhanced revision control; versus 1.5SMC16A, it trades thermal capacity for compactness - making SMBJ16C-E3/5B optimal for high-density consumer and telecom designs where 0.2" × 0.2" pad area is constrained.

FAQ
What is the clamping voltage of SMBJ16C-E3/5B under a 10/1000 µs surge?
The SMBJ16C-E3/5B has a maximum clamping voltage (VC) of 26.0 V at 23.1 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and guarantees that protected circuits will not experience more than 26.0 V during specified surge events - a critical parameter for ensuring compatibility with 3.3 V, 5 V, and 12 V logic and power domains. The SMBJ16C-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ16C-E3/5B RoHS-compliant and lead-free?
Yes, SMBJ16C-E3/5B is RoHS-compliant and lead-free, as confirmed by the "E3" suffix in its ordering code. It uses matte tin-plated leads and meets JESD 201 Class 2 whisker resistance requirements. The molding compound complies with UL 94 V-0 flammability rating, and the device is qualified per J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C - making SMBJ16C-E3/5B fully compatible with modern lead-free SMT assembly processes.
How does SMBJ16C-E3/5B differ from bidirectional variants like SMBJ16CA?
SMBJ16C-E3/5B is unidirectional, meaning it conducts only in reverse bias above its breakdown voltage and blocks forward current up to 3.5 V (VF max at 50 A). In contrast, SMBJ16CA is bidirectional and symmetrical - conducting in both directions above ±16 V. This makes SMBJ16C-E3/5B ideal for DC power rail protection where polarity is fixed, while SMBJ16CA suits AC-coupled or floating signal lines. The SMBJ16C-E3/5B cathode band clearly identifies polarity, unlike the unmarked SMBJ16CA.
What is the maximum operating temperature for SMBJ16C-E3/5B?
The SMBJ16C-E3/5B has a maximum junction temperature (TJ max) of +150 °C and an operating junction and storage temperature range of -55 °C to +150 °C. Its thermal resistance is RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads, so derating is required above 25 °C ambient - for example, at 70 °C ambient, maximum power dissipation drops to ~2.5 W. This rating enables reliable operation in under-hood automotive, industrial motor drives, and enclosed telecom equipment where SMBJ16C-E3/5B is commonly deployed.
Can SMBJ16C-E3/5B be used in place of SMBJ16A-E3/5B?
Yes, SMBJ16C-E3/5B is functionally identical to SMBJ16A-E3/5B: both share the same VWM (16 V), VBR (17.8–19.7 V), VC (26.0 V), PPPM (600 W), and SMB (DO-214AA) package. The "C" suffix denotes a revision-controlled variant per Vishay's documentation (Revision: 09-Jan-2024), with no electrical or mechanical differences. Engineers may substitute SMBJ16C-E3/5B for SMBJ16A-E3/5B without layout or performance impact - and benefit from updated compliance documentation and traceability.
